Nexus 7 or Kindle Fire Which One Should You Buy

Nexus 7
Nexus 7 and the Kindle Fire are two hot and favorable android tablets at present,and most of people cannot decide to buy which one.My suggestion is buy the Nexus 7 unless youre a huge Amazon user. Then get the Fire.

There you go. No beating around the bush. Just a simple answer. Or is it?

Lets regroup for a second and really look at the question. The Kindle Fire is Amazons $199 7-inch Android-based Kindle device. Its WiFi-only. The Nexus 7 is Googles $199 7-inch Android device. Its also WiFi-only.

Now you can see why theres some level of confusion. The two devices are the same size and the same price. There are some differences, however.

Physical device

The Kindle Fire weights 2.6 ounces more than the Nexus 7. Its 14.6 ounces, while the Nexus 7 is 12 ounces. In a handheld device, 2 ounces is something youll notice.

More to the point, the Nexus 7 is a lot more machine for your $199. Its got a much faster CPU, a graphics processor, twice the RAM of the Kindle Fire, and (for an extra fifty bucks) can store twice as much as the Kindle Fire.

On raw horsey-power, the Nexus 7 gets the win.

Android OS

Although both devices are based on Android, youd be hard-pressed to notice Android on the Kindle Fire. The Kindle Fire is a Kindle first, with Android 2.3 running underneath, hidden from view.

On the other hand, the Nexus 7 is Googles current benchmark tablet, running Android 4.1 (otherwise known as Jelly Bean).

On Android compatibility, the Nexus 7 gets the win.

Software compatibility

Heres where things start getting interesting. Youd think the Nexus 7 would run more Android apps, but because its the first Jelly Bean product in a 7-inch tablet form, many Android apps (like Instagram) wont run because they check the version number. 4.1 is higher than many apps are comfortable with.

On the other hand, the Kindle Fire runs apps primarily from the Amazon app store. While you can side-load regular Android apps, theres some hoop jumping involved.

When it comes to software compatibility, at the time of writing, neither wins the top slot. Its a draw.

Gaming

There are quite a few nice, little games for the Kindle Fire. But the Nexus 7 has a built-in Tegra 3 T30L graphics processing unit. Almost, without a doubt, and especially since the system also has twice the RAM, the Nexus 7 will be the better gaming machine.

Nexus 7 gets the win.

Security

This one is interesting. Android security is somewhat problematic, especially if you decide to download apps from secondary app stores. Apps purchased through Amazon have a much higher chance of being safe. In fact, the entire Kindle experience is tied into your Amazon account, and is secured by Amazons relatively strong attention to detail.

For security, the Kindle Fire gets the win.

Media

Heres where Amazon takes the lead from Google. Amazon has a rich media experience, and also provides a substantial library of free movies and TV shows to Prime customers. Google Play isnt nearly as good. Jason Perlow also pointed out that only actual Kindle devices (not just those devices running Kindle software, like an iPhone), can take things out from the Kindle Lending Library. So if you want to read best-sellers for free, the Fire is your best bet.

On the other hand, the Nexus 7 will play that media better, because it has substantially more power and a higher-resolution display.

Well call this a draw.

Which should you get?

Without a doubt, the Kindle Fire is a Kindle, while the Nexus 7 is an Android tablet. If you want a Kindle more than you want an Android tablet, then you might be happier with the Kindle Fire. Likewise, if you want to stay out of the morass that is the Android ecosystem and just want to stay in the welcoming, comforting arms of Amazon, youll be happier with the Kindle Fire.

Kindle FireOn the other hand, if you want a powerful, inexpensive, solidly designed pure Android tablet, the Nexus 7 is a no-brainer.

My wife and I have two iPads and two Kindle Fires at home. Im honestly thinking about selling my Kindle Fire and getting a Nexus 7 to replace it. If you do decide to sell your Kindle Fire, make sure you remember to decommission it before you sell it. Otherwise, the device has access to your entire Amazon account.

Hmmm...maybe the Kindle Fire isnt that secure, after all.

Yahoo Mail users Mandatory Use New Interface


November of 2012 yesterday, rumors began circulating about a Yahoo email user interface to be similar to Gmail. And about a month rumors emerged, Yahoo officially announced Yahoo Mail with a new look. Since that Yahoo gave option to the user to choose whether they want a new interface or keep the classic look. Now starting from June 3, every Yahoo! Mail user would not want to move to the new interface. For users who did not want to upgrade, they must stop using the service entirely or use it via IMAP, but still there is no option to go back to the classic interface. 

The new interface has a service agreement terms and privacy policy which must be approved by new users if they want to continue using this service.

Top 50 OOPs Interview Questions and Answers

OOPS Interview Questions and Answers

Also Read: Top 50 Common Job Interview Questions and answers


1. What is OOPS?

OOPS is abbreviated as Object Oriented Programming system in which programs are considered as a collection of objects. Each object is nothing but an instance of a class.

2. Write basic concepts of OOPS?

Following are the concepts of OOPS and are as follows:.
Abstraction.
Encapsulation.
Inheritance.
Polymorphism.


3. What is a class?

A class is simply a representation of a type of object. It is the blueprint/ plan/ template that describe the details of an object.


4. What is an object?

Object is termed as an instance of a class, and it has its own state, behavior and identity.


5. What is Encapsulation?

Encapsulation is an attribute of an object, and it contains all data which is hidden. That hidden data can be restricted to the members of that class.

Levels are Public,Protected, Private, Internal and Protected Internal.


6. What is Polymorphism?

Polymorphism is nothing butassigning behavior or value in a subclass to something that was already declared in the main class. Simply, polymorphism takes more than one form.


7. What is Inheritance?

Inheritance is a concept where one class shares the structure and behavior defined in another class. Ifinheritance applied on one class is called Single Inheritance, and if it depends on multiple classes, then it is called multiple Inheritance.


8. What are manipulators?

Manipulators are the functions which can be used in conjunction with the insertion (<<) and extraction (>>) operators on an object. Examples are endl and setw.


9. Define a constructor?

Constructor is a method used to initialize the state of an object, and it gets invoked at the time of object creation. Rules forconstructor are:.
Constructor Name should be same asclass name.
Constructor must have no return type.


10. Define Destructor?

Destructor is a method which is automatically called when the object ismade ofscope or destroyed. Destructor name is also same asclass name but with the tilde symbol before the name.


11. What is Inline function?

Inline function is a technique used by the compilers and instructs to insert complete body of the function wherever that function is used in the program source code.


12. What is avirtual function?

Virtual function is a member function ofclass and its functionality can be overridden in its derived class. This function can be implemented by using a keyword called virtual, and it can be given during function declaration.


Virtual function can be achieved in C++, and it can be achieved in C Languageby using function pointers or pointers to function.


13. What isfriend function?

Friend function is a friend of a class that is allowed to access to Public, private or protected data in that same class. If the function is defined outside the class cannot access such information.

Friend can be declared anywhere in the class declaration, and it cannot be affected by access control keywords like private, public or protected.


14. What is function overloading?

Function overloading is defined as a normal function, but it has the ability to perform different tasks. It allowscreation of several methods with the same name which differ from each other by type of input and output of the function.

Example
void add(int& a, int& b);
void add(double& a, double& b);
void add(struct bob& a, struct bob& b);


15. What is operator overloading?

Operator overloading is a function where different operators are applied and depends on the arguments. Operator,-,* can be used to pass through the function , and it has their own precedence to execute.

Example:
class complex {
double real, imag;

public:
complex(double r, double i) :
real(r), imag(i) {}
complex operator+(complex a, complex b);
complex operator*(complex a, complex b);
complex& operator=(complex a, complex b);
}

a=1.2, b=6


16. What is an abstract class?

An abstract class is a class which cannot be instantiated. Creation of an object is not possible withabstract class , but it can be inherited. An abstract class can contain only Abstract method.


17. What is a ternary operator?

Ternary operator is said to be an operator which takes three arguments. Arguments and results are of different data types , and it is depends on the function. Ternary operator is also called asconditional operator.


18. What is the use of finalize method?

Finalize method helps to perform cleanup operations on the resources which are not currently used. Finalize method is protected , and it is accessible only through this class or by a derived class.


19. What are different types of arguments?

A parameter is a variable used during the declaration of the function or subroutine and arguments are passed to the function , and it should match with the parameter defined. There are two types of Arguments.
Call by Value – Value passed will get modified only inside the function , and it returns the same value whatever it is passed it into the function.
Call by Reference – Value passed will get modified in both inside and outside the functions and it returns the same or different value.


20. What is super keyword?


Super keyword is used to invoke overridden method which overrides one of its superclass methods. This keyword allows to access overridden methods and also to access hidden members of the superclass.

It also forwards a call from a constructor to a constructor in the superclass.


21. What is method overriding?

Method overriding is a feature that allows sub class to provide implementation of a method that is already defined in the main class. This will overrides the implementation in the superclass by providing the same method name, same parameter and same return type.


22. What is an interface?

An interface is a collection of abstract method. If the class implements an inheritance, and then thereby inherits all the abstract methods of an interface.


23. What is exception handling?

Exception is an event that occurs during the execution of a program. Exceptions can be of any type – Run time exception, Error exceptions. Those exceptions are handled properly through exception handling mechanism like try, catch and throw keywords.


24. What are tokens?

Token is recognized by a compiler and it cannot be broken down into component elements. Keywords, identifiers, constants, string literals and operators are examples of tokens.

Even punctuation characters are also considered as tokens – Brackets, Commas, Braces and Parentheses.


25. Difference between overloading and overriding?

Overloading is static binding whereas Overriding is dynamic binding. Overloading is nothing but the same method with different arguments , and it may or may not return the same value in the same class itself.

Overriding is the same method names with same arguments and return types associates with the class and its child class.


26. Difference between class and an object?

An object is an instance of a class. Objects hold any information , but classes don’t have any information. Definition of properties and functions can be done at class and can be used by the object.

Class can have sub-classes, and an object doesn’t have sub-objects.


27. What is an abstraction?

Abstraction is a good feature of OOPS , and it shows only the necessary details to the client of an object. Means, it shows only necessary details for an object, not the inner details of an object. Example – When you want to switch On television, it not necessary to show all the functions of TV. Whatever is required to switch on TV will be showed by using abstract class.


28. What are access modifiers?

Access modifiers determine the scope of the method or variables that can be accessed from other various objects or classes. There are 5 types of access modifiers , and they are as follows:.
Private.
Protected.
Public.
Friend.
Protected Friend.


29. What is sealed modifiers?

Sealed modifiers are the access modifiers where it cannot be inherited by the methods. Sealed modifiers can also be applied to properties, events and methods. This modifier cannot be applied to static members.


30. How can we call the base method without creating an instance?

Yes, it is possible to call the base method without creating an instance. And that method should be,.

Static method.
Doing inheritance from that class.-Use Base Keyword from derived class.


31. What is the difference between new and override?

The new modifier instructs the compiler to use the new implementation instead of the base class function. Whereas, Override modifier helps to override the base class function.


32. What are the various types of constructors?

There are three various types of constructors , and they are as follows:.

- Default Constructor – With no parameters.

- Parametric Constructor – With Parameters. Create a new instance of a class and also passing arguments simultaneously.

- Copy Constructor – Which creates a new object as a copy of an existing object.


33. What is early and late binding?

Early binding refers to assignment of values to variables during design time whereas late binding refers to assignment of values to variables during run time.


34. What is ‘this’ pointer?

THIS pointer refers to the current object of a class. THIS keyword is used as a pointer which differentiates between the current object with the global object. Basically, it refers to the current object.


35. What is the difference between structure and a class?

Structure default access type is public , but class access type is private. A structure is used for grouping data whereas class can be used for grouping data and methods.
Structures are exclusively used for dataand it doesn’t require strict validation , but classes are used to encapsulates and inherit data which requires strict validation.


36. What is the default access modifier in a class?

The default access modifier of a class is Private by default.


37. What is pure virtual function?

A pure virtual function is a function which can be overridden in the derived classbut cannot be defined. A virtual function can be declared as Pure by using the operator =0.

Example -.

Virtual void function1() // Virtual, Not pure
Virtual void function2() = 0 //Pure virtual


38. What are all the operators that cannot be overloaded?

Following are the operators that cannot be overloaded -.
Scope Resolution (:: )
Member Selection (.)
Member selection through a pointer to function (.*)


39. What is dynamic or run time polymorphism?

Dynamic or Run time polymorphism is also known as method overriding in which call to an overridden function is resolved during run time, not at the compile time. It means having two or more methods with the same name,same signature but with different implementation.


40. Do we require parameter for constructors?

No, we do not require parameter for constructors.


41. What is a copy constructor?

This is a special constructor for creating a new object as a copy of an existing object. There will be always only on copy constructor that can be either defined by the user or the system.


42. What does the keyword virtual represented in the method definition?

It means, we can override the method.


43. Whether static method can use non static members?

False.


44. What arebase class, sub class and super class?

Base class is the most generalized class , and it is said to be a root class.

Sub class is a class that inherits from one or more base classes.

Super class is the parent class from which another class inherits.


45. What is static and dynamic binding?

Binding is nothing but the association of a name with the class. Static binding is a binding in which name can be associated with the class during compilation time , and it is also called as early Binding.

Dynamic binding is a binding in which name can be associated with the class during execution time , and it is also called as Late Binding.


46. How many instances can be created for an abstract class?

Zero instances will be created for an abstract class.


47. Which keyword can be used for overloading?

Operator keyword is used for overloading.


48. What is the default access specifier in a class definition?

Nexus 10 vs iPad 4 vs Surface RT vs Kindle Fire HD 8.9 
My Opinion
In terms of weight, the Kindle Fire HD 8.9 takes this category as the lightest, but in terms of mobility, the revamped iPad 4 is the winner. And if you are Amazon fans,maybe you want to get the Amazon Kindle Fire HD 8.9 for its attractive Amazon service.

The Windows RT boasts a quad-core processor, promising better performance than most its rivals. It’s also ripe with Microsoft Office capabilities, so those who are very familiar with using Microsoft Office for productivity will surely enjoy using the RT.


iPad 4 will also be hot with its A6X processor for Apple fans and others. If you consider of the price,then Kindle Fire HD 8.9 and Nexus 10 will be your options.


Whatever, just make a wise choice.

How to Download Free Music for Android Phone or Android Tablet


get free music for Android
Video and music surely play an important role in entertainment on Android smartphones and tablets. I have written the article on free downloading YouTube on Android a few days ago, so how to download free music for Android or how to get free music for Android? Here I would like to share 3 best ways to get free music to Android phone or Android tablet.

1.Get free hot music without Virus via PC 
When we download things from the web, the thing we may be worried about is if it is safe. So, I just want to suggest you to record the music from the music streaming website with an audio recording tool on PC. Fresh, isn’t it? And you can just find your favorite music on the Internet and then record it and transfer it to your Android. Not complicated to get free hot music.

As for the audio recording tool, I really want you to try this music recorder. The tool can record hot audio and music going with album cover and other song tags. The source can be from computer streaming audio, many famous online music website like YouTube, AOL Music, Last.fm, etc, Mic, and other built-in input audio stream. You can use Task Scheduler to take control of the recording project. Also, it can act as a great music player for your PC. Operation is very simple and you can do it according to the guide on its website.

Strongly Recommend: Now only $9.95 for this cool music recording tool.

2.Use free Android apps to download free music for Android
Of course, there are some free Android apps letting us download free music on Android. But note that free music may be something kind of old and unpopular. Then all you need to do is download a free music downloading app, install and launch it, and finally search and download music.

For free music downloading app for Android, I would like to suggest Download free music MP3 App and MP3 Music Download Pro. Download Free music MP3 app is very simple but useful in searching and downloading millions of free music and MP3s from public search engine. MP3 Music Download Pro offers the similar service like Download Free music MP3 app, but the music can be downloaded with lyric and Album cover. The highlight of MP3 Pro is you can cut the songs you downloaded and set them as ringtones.

3.Go to Website to download free music for Android
Indeed, there are some websites which offers the free music, and benefiting from the technology, our Android smartphones and tablets can download free music from the website just like PC. You can check these safe and legal websites: Amazon, ccmixter, last.fm, freemusicarchive and more. Note that, these free music are probably not the hot music or the music on the radio.

So, what’s your choice?
