What is .class File and Bytecode

• At the point when Java source document is gathered by Java compiler, it is changed over into Java class record with .class augmentation.
• The Java class document contains Java bytecode (exceptionally advanced arrangement of directions) which is executed by Java Virtual Machine (JVM).
• .class document contains images and each bytecode guidance is put away into one byte precisely.
• .class document of each class is independently put away. Its name is same as class name in the source record.
• A Java program can have any number of classes. On the off chance that beneath program is accumulated, at that point, two .class documents will be made with name A.class and B.class.

class A
{


public static void main(String…s)


{


System.out.println(“A”);


}


}





class B
{


public static void main(String…s)


{


System.out.println(“B”);


}


}

• A .class document can be executed on any working framework; we simply need JVM of that working framework. This makes Java machine free.
