    Default Re: keyword super in java

    There are so many uses of super keyword.
    Used to refer immediate parent class instance variable.
    Used to invoke parent class constructor.

    class Parent{  
    Parent(){
    System.out.println("In Parent class constructor");
    }  
    }
     
    class Child extends Parent{  
    Child (){  
    super();//will invoke parent class constructor    
    }  
    public static void main(String args[]){  
    Child child =new Child ();  
    }  
    }

    and as it refer to immediate parent class instance variable so it also used to call a method of parent class.

    super.ParentClassMethod();
