Java Method Overriding | HackerRank Solution

Hello coders, today we are going to solve Java Method Overriding HackerRank Solution.

Java Method Overriding

Contents

Problem

When a subclass inherits from a superclass, it also inherits its methods; however, it can also override the superclass methods (as well as declare and implement new ones). Consider the following Sports class:

class Sports{
    String getName(){
        return "Generic Sports";
    }
    void getNumberOfTeamMembers(){
        System.out.println( "Each team has n players in " + getName() );
    }
}

Next, we create a Soccer class that inherits from the Sports class. We can override the getName method and return a different, subclass-specific string:

class Soccer extends Sports{
    @Override
    String getName(){
        return "Soccer Class";
    }
}

Note : When overriding a method, you should precede it with the @Override annotation. The parameter(s) and return type of an overridden method must be exactly the same as those of the method inherited from the supertype.

Task

Complete the code in your editor by writing an overridden getNumberOfTeamMembers method that prints the same statement as the superclass’ getNumberOfTeamMembers method, except that it replaces with (the number of players on a Soccer team).

Output Format

When executed, your completed code should print the following:

 Generic Sports
 Each team has n players in Generic Sports
 Soccer Class
 Each team has 11 players in Soccer Class

Solution – Java Method Overriding

import java.util.*;
class Sports{

    String getName(){
        return "Generic Sports";
    }
  
    void getNumberOfTeamMembers(){
        System.out.println( "Each team has n players in " + getName() );
    }
}

class Soccer extends Sports{
    @Override
    String getName(){
        return "Soccer Class";
    }

    // Write your overridden getNumberOfTeamMembers method here
    @Override
void getNumberOfTeamMembers () {
       System.out.println( "Each team has 11 players in " + getName() );
}

}

public class Solution{
	
    public static void main(String []args){
        Sports c1 = new Sports();
        Soccer c2 = new Soccer();
        System.out.println(c1.getName());
        c1.getNumberOfTeamMembers();
        System.out.println(c2.getName());
        c2.getNumberOfTeamMembers();
	}
}
