Hi,

the common way would be to pass the lists into the function and only have
them filled by the function like:

public static void getStudentResults( int studentId, List scores, List
subjects ) {
...
}

You could as well return a List[] or a List of Lists, or you can also create
a StudentResult object having subject and score as member and return a list
of StudentResults like:

public static List<StudentResult> getStudentResults( int studentId ) {
....
}

public class StudentResult {
String score;
String subject;
}

As you can see there are some possibilities. Which you take is more or less
a matter of personal taste and of course the design of your application.

Best regards,
Jan

I have a query regarding a static method. Is it possible to return
multiple objects from the method?

e.g. method getStudentResults below has got 2 Lists and a boolean. How
do I pass them back to the calling method?

public static List getStudentResults(int studentId)
{
    List scores = getScores(studentId); // need to pass back
    List subjects = getSubjects(studentId); // need to pass back
    boolean isQualified = true; // need to pass back

    return scores;
}
