Problem statement

In this program, we will create an abstract class with a non-abstract method. Then we will inherit the abstract class into another class.

Java program to create an abstract class without any abstract method

The source code to create an abstract class without any abstract method is given below. The given program is compiled and executed successfully.

// Java program to create an abstract class 
// without any abstract method

abstract class AbsClass {
  void MyFun() {
    System.out.println("MyFun() called");
  }
}

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 non-abstract 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.
