Write a Java program to demonstrate use of 'final' keyword.
Source Code
class A {
void show() {
System.out.println("Inside A");
}
}
class B extends A {
final double PI = 3.14;
int x = 10;
void show() {
System.out.println("Inside B");
x = 20;
System.out.println("x = " + x);
System.out.println("PI = " + PI);
}
public static void main(String args[]) {
B objB = new B();
objB.show();
A objA = new A();
objA.show();
}
}
Output
Inside B
x = 20
PI = 3.14
Inside A
