The source code to create an abstract class with a final method is given below. The given program is compiled and executed successfully.

// Java program to create an abstract class 
// with a final method

abstract class AbsClass {
  final void MyFun() {

  }
}

class Sample extends AbsClass {

}

public class Main {
  public static void main(String[] args) {
    AbsClass abs = new Sample();
    abs.MyFun();
  }
}

Output

MyFun() called

Explanation

In the above program, we created an abstract class AbsClass with a final method. Then we will inherit the AbsClass into the Sample class.

The Main class contains a method main(). The main() method is the entry point for the program, here we created a reference of AbsClass and initialized it with the reference of Sample class. Then we called MyFun() method using the reference of AbsClass.
