Overriding in Java with an simple code

The specialties of Overriding

1. @Override annotation needed. 

2. The parameter(s) and return type must be the same as an inherited from its superclass. 

3. Super keyword needs to refer to a parent class.

4. Final methods, private methods and Static methods cannot be overridden.

5. a method overriding can only be written in a subclass, not in the same class.

Example Code

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 // annotation
    String getName(){ // The same parameter
        return "Soccer Class"; // The same return type
    }
    @Override
    void getNumberOfTeamMembers(){
        System.out.println("Each team has 11 players in " + getName() );
    }
}
