Java Method Overriding HackerRank Solution

Hello Programmers, In this post, you will know how to solve the Java Method Overriding HackerRank Solution. This problem is a part of the HackerRank Java Programming Series.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Java Method Overriding HackerRank Solution

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

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