    Question and Answer




1. What is JAVA?

Java is the object-oriented high-level and secure programming language with high performance, Multithreaded, and portable programming language which is platform-independent.

2. Who developed JAVA and when?

in June 1991 James Gosling developed it.

3. What are the differences between C++ and Java?

4. What do you mean by JVM (Java virtual machine)?

JVM is a virtual machine that allows the computer to run the Java program. JVM acts like a run-time engine which calls the main method present in the Java code. The Java code is totally compiled by JVM to convert it into Bytecode which is machine independent.

5. What is the difference between JDK, JRE, and JVM?

JVM: It is an abstract machine which provides the runtime environment to execute Java bytecode. It specifies the working of Java Virtual Machine and Oracle as well as some other companies provided its implementation. Its implementation is known as JRE.

JRE: JRE stands for Java Runtime Environment. It is the implementation of JVM. The JRE is a set of software tools which are used to develop Java applications and also to provide the runtime environment for it. It contains a set of libraries + other files that JVM uses at runtime.

JDK: JDK is an acronym for Java Development Kit. It is a software development environment which is used to develop Java applications and applets. It contains JRE + development tools.

6. What is JIT (Just-In-Time) compiler?

(JIT) compiler is used to improve the performance. JIT compiles parts of the bytecode that have similar functionality at the same time, and hence reduces the amount of time needed for compilation.

7. What do you mean by the term platform?

A platform is the hardware or software environment in which execution of a piece of software takes place. There are two types of platforms: software-based and hardware-based. Java provides the software-based platform

8. Is Java platform independent?

Yes. Java is a platform independent language. We can write java code on one platform and run it on another platform. For e.g. we can write and compile the code on windows and can run the generated bytecode on Linux or any other supported platform.

9. How many types of memory areas are allocated by JVM?

Many types:

1. Class(Method) Area: It stores per-class structures such as the runtime constant field, method data, and the code for methods.

2. Heap: It is the runtime data area in which an objects is assigned the memory.

3. Stack: It holds local variables and partial results, and plays a part in method invocation and return. Each thread has a private JVM stack which is created at the time of thread. A new frame is created each time a method is invoked and destroyed when its method invocation completes.

4. Program Counter Register: PC (program counter) register contains the address of the Java virtual machine instruction which is currently executed.

5. Native Method Stack: It contains all the native methods which are used in the creation of an application.

10. gives Java its 'write once and run anywhere' nature?

Java compiler converts the Java programs into the class file (i.e.Byte Code) which is the intermediate language between source code and machine code. This bytecode is not platform dependent and can be executed on any computer

11. Is Empty.java file name a valid source file name?

Yes, Java allows to save our java file by .java only, we need to compile it by javac .java and run by java classname Let's take a simple example:
//save by .java only
class A{
public static void main(String args[]){
System.out.println("Hello java");
}
}
It will be compile by javac .java
It will run by java A


12. ) Explain public static void main(String args[])

public : It is an identifier which allows a Class, Method, Field to be accessible from anywhere.

static : static is a keyword which tells that this method can be accessed without creating the instance of the class.

void this main method returns no value.

main It is the name of the method from where a program initially starts.

String args[]: The args is an array of String type. This contains the command line arguments that we can pass while running the program.

13. What is javac ?

The javac is a compiler that compiles the source code of a program and generates bytecode.

14. What are the various access specifiers for Java classes?

The types of access specifiers for classes are:
1. Public : Class, Method, Field is accessible from anywhere.

2. Protected: Method, Field can be accessed from the same class to which they belong or from the sub-classes, and from the class of same package, but not from outside.

3. Default: Method, Field, class can be accessed only from the same package and not from outside of it's native package.

4. Private: Method, Field can be accessed from the same class to which they belong.

15. What is the base class of all classes?

In Java, among all the classes, java.lang.Object is the base class (super class).

16. What is a wrapper class in Java?

A wrapper class is a class that converts the primitive data type to the objects of their respective classes. For example, int is a primitive data type which is converted into its object class as Integer by the wrapper class.

17. What is Unicode?

Unicode defines a fully international character set that can represent all of the characters found in human languages or world’s writing system. Java uses Unicode to represent the characters.

18. What is the purpose of static methods and variables?

The static methods or variables are shared among all the objects of the class. The static is the part of the class and not of the object. The static variables not need to create the object. Therefore, static is used in the case, where we need to define variables or methods which are common to all the objects of the class.

19. What are Java Packages?

In Java, package is a collection of classes and interfaces which relates to each other as they are bundled together.
