Hints 
They are three purpose to use super keyword.

1. To call super class constructors from sub class constructors.
    super();
    super(10,20);

2. To access super class member variables. This is not accessible by sub class If sub class has the same variable name otherwise super.
   super.variable_name = 10;

3. To call super class methods. This is not accessible by sub class If sub class has the same method name which is in super class.
   super.display();
Example
class Cricket {
    int runs;
    int over;
    
    public Cricket(){
        over = 99;
    }
    
    public void display(){
        System.out.println("Runs: "+runs+";Over: "+over);
    }
}

class CricketCounter extends Cricket{
    public CricketCounter(){
        super();
    }
    public void display(){
        super.runs = 82;
        super.display();
    }
}

class Solution {
