Answer to Question #258549 in Java | JSP | JSF for liza

Question

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. 

Answer 1

SOLUTION FOR THE ABOVE QUESTION

In this problem we will modify the getNumberOfTeamMembers() function to take a value n of int type as a parameter representing the number of team members of a given team.

Inside the main method, We will instantiate an object of the soccer class and prompt the user for to enter the number of team members and display then display the number of players in each team of the given sports name given by the overridden getName() function of the soccer class
