Sum of GPA

[hoangx87]

Instruction:

Write StudentStatisticCalculator.java
An interface with two methods:
getName(), which returns a String
computeStatistic(Student[] students), which returns a double

You'll write 4 classes that implement the StudentStatisticCacluator interface,
to find the sum, min, max, and average gpa in the student array passed to printStatistic.



public interface StudentStatisticCalculator{


public String getName();


public double computeStatistic(Student[] students);


}





public class SumGpa implements StudentStatisticCalculator {

String name;


public SumGpa(){
}

public String getName(){
return name;
}

public double computeStatistic(Student[] students){
return 1;
}


public static void main(String args[]){
SumGpa s=new SumGpa();


}



}

I was wondering if I am missing something, and I would like to know what would i have to do to get the sum of the gpa.

Why did you make this new thread for the same basic question?

[hoangx87]

i guess it was a different question now.

I posted something in the previous thread. While this is compilable and runnable what happens when you call compute? Does it produce the sum of the argument array?
