When a class file gets created in Java? |
|
Answer» The JAVA CLASS file has a .class extension and contains the Java bytecode. This class file can be executed by the Java Virtual Machine. The Java class file is created as a result of successful compilation by the Java compiler from the .java file. Each class in the .java file is compiled into a separate class file if the .java file has more than one class. A program that demonstrates the creation of a class file in Java is given as FOLLOWS: class A { A() { System.out.println("This is class A"); } } class B { B() { System.out.println("This is class B"); } } public class Demo { public static void main(String[] args) { A obj1 = new A(); B OBJ2 = new B(); } }The output of the above program is as follows: This is class A This is class BAfter the above program is compiled successfully, there are 3 class files created in the corresponding folder as there are 3 CLASSES in the .java file. These class files are A.class, B.class and Demo.class. |
