public class SubClass extends SuperClass{
    public static void main(String args[]){
        SubClass subClass=new SubClass();
        subClass.display();
        subClass.display(10);
    }
    int x;
    void display(){
        System.out.println("inside display() of SubClass");
    }
    void display(int x){
        this.x=x;;
        System.out.println("inside display("+x+") of SubClass");
    }
}

class  SuperClass{
    int x;
    void display(){
        System.out.println("inside display() of SuperClass");
    }
    void display(int x){
        this.x=x;;
        System.out.println("inside display("+x+") of SuperClass");
    }
}


Output:
inside display() of SubClass
inside display(10) of SubClass
