Answer 1

Super at Constructer level

    class SuperClass
{
    int num=10;
    public void display()
    {
        System.out.println("Superclass display method");
    }
}
class SubClass extends SuperClass
{
    int num=20;

    public void display()
    {
        System.out.println("the value of subclass variable name:"+num);
        System.out.println("Subclass display method");
    }
        public void Mymethod()
        {
            super.display();
            System.out.println("the value of superclass variable name:"+super.num);
        }
        public static void main(String[] args)
        {
            SubClass obj=new SubClass();
            obj.Mymethod();
            obj.display();
        }
}
