returning values

[Graham Robinson]

I have it so it will return 1 value, but if i need to take it more than one value in my class how would i do it?

The example here should take the grades of 4 students, to find the average but i don't know how to take it more than one, here's some code.

/*
 * StudentV2.java
 *
 * 
 */
 
public class StudentV2{
 
private int theCWGrade;
private int theExamGrade;
private String theStudentName;
private int theCWAverage;
private int theExamAverage;
 

public StudentV2(){
theStudentName = "John Doe";
theExamGrade = 0;
theCWGrade = 0;
theExamAverage = 0;
theCWAverage = 0;
 

}
 
public StudentV2(String name, int examGrade, int cwGrade, int cwAverage, int examAverage, boolean pass){
theStudentName = name;
theExamGrade = examGrade;
theCWGrade = cwGrade;
theCWAverage = cwAverage;
theExamAverage = examAverage;
 
}
 
public void setName(String name){
theStudentName = name;
}
 
public void setExamGrade(int grade){
theExamGrade = grade;
}
 
public void setCWGrade(int grade){
theCWGrade = grade;
}
 
public void setCWAverage(int average){
theCWAverage = average;
}
 
public void setExamAverage(int average){
theExamAverage = average;
}
 

public String getName(){
return theStudentName;
}
 
public int getExamGrade(){
return theExamGrade;
}
 
public int getCWGrade(){
return theCWGrade;
}
 
[B]public int CWAverage(){
return (getCWGrade() / 4);
}
 
public int ExamAverage(){
return (getExamGrade() / 4);[/B]
}
 
public double overallGrade(){
return (0.4*getCWGrade() + 0.6*getExamGrade());
}
 
public boolean moduleResult(){
return ((overallGrade()>=3.0) && (getCWGrade()>=2) && (getExamGrade()>=2));
 

}
}

this is link to a file called marks, where the grades of four students are entered using an array.

Cheers.

I'm not clear about your question.

If you are asking if you can return more than one value from a method, you can't.

If you want multiple values from a method, you should encapsulate them in a class definition and return an instance of that class.

Your English is difficult to understand (perhaps you could get someone who speaks better English to write your post) but I think you are asking how to find the average grade of a group of students. An instance of StudentV2 represents *one* student, so I don't think it makes sense for such an object to know the average of four students. You could define a class, say StudentCohort, that holds a collection of students. If you ask a cohort for its average, it will find that out by asking each individual for its grade, then doing the math.
