I have two erros which I have tried everything to fix them

C:\Documents and Settings\java:14: array required, but java.lang.String found
        ID[count] = ID;
          ^
C:\Documents and Settings\java:15: array required, but int found
        mark[count] = mark;

heres the code

class Module
 {
     String[] ID = new String[10];
      int[] score = new int[10];

    int setID(String ID, int mark, int count){
        //id, mark and count get passed from the main method
        ID[count] = ID;
        score[count] = mark;


       }

Would you mind posting the full code in the code brackets so I can get a feel for what your trying to do?

heres the main method then

import javax.swing.*;


public class Test{
/** Main method */
public static void main(String[] args) {


for(int count = 0;count<10;count++){
String ID = JOptionPane.showInputDialog(null,
"Enter the Students ID",
"Programming 2",
JOptionPane.QUESTION_MESSAGE);


String num = JOptionPane.showInputDialog(null,
"Enter the Students score",
"Programming 2",
JOptionPane.QUESTION_MESSAGE);


int mark = Integer.parseInt(num);



Module withData = new Module(ID, mark, count);


System.out.println("Student data   = "+ withData.setID());



}

The elements of ID, mark or whatever have to be of the same type as what those arrays are...

String[] ID = new String[12];

int[] mark = new int[12];
