every one say that java is independent language.we have develop some java program to understand how java is platform independent.
public class Add{
public static void main(String []ar){
int a=10;
int b=20;
int a=a+b;
}
}
save the above program by Add.java
to run this program first we have to compile the program by using javac Add.java.after compile the program it generates Add.class file.Generally .class file contains javainstructions.we can not run the .class file directly on to the processor.so in this we require some virtual machine.so we have to instal jvm.To give the .class file input to the jvm.The jvm converts java instructions into the processor dependent instructions.so jvm is a dependent language.Wiothout jvm we will not able to run our java program.so in this way we say that java is independent language.
