Heres whats going on, I need a program for class that...

1. asks for number of students.
2. give an input box for their name.
3. give an input box for student score.
4. repeat steps 3 and 4 as many times as inputed in step 1.
5. show the students scores in highest to lowest order with the average.
6. must check for errors.
7. if a number is put where a letter should be or vise versa it must be caught until user quits or enters right response.

now here is where I stand and I will be standing for a long time because I just don't know how to get all that to work. He said something about "arrays" but did not say much about them. I am lost and need much o help here

Code:

 	import javax.swing.*;
 
 public class kthLab3
 {
 	
 	public static void main(String [] args)
 	{
 		progra();
 		System.exit(0);
 	}
 	
 	public static void progra()
 	{	
 		intro();
 		numberOf();	
 	}
 
 	public static void intro()
 	{
 		JOptionPane.showMessageDialog(null, "This program will take a given number of students and show you the user their scores from highest to lowest with the class average.");
 	}
 	
 	public static void numberOf()
 	{
 		String response;
 		
 		response = JOptionPane.showInputDialog("Enter number of students.");
 		
 		if (response == null){JOptionPane.showMessageDialog(null, "You have chose to quit using the program.");
			System.exit (0);}
 	
 		else 
	    	{response = JOptionPane.showInputDialog 
	    	("Please enter a number.");}
 	
 		response = JOptionPane.showInputDialog("What is the students name?");
