Help with program! (Beginner)

Question

Here is what I'm trying to do:
lo : Smallest. Write a program that allows a user to enter a series of positive integers with a -99 to signal the end of the series. The program should then display the smallest of the numbers in the series. Do not use a bogus value for the smallest to begin the program. Use the first value in the data list (if any) to initialize your smallest. This program must have only one programmer-defined method other than main which outputs user directions to the console about how the program works (and that -99 is to be used to end the input). Note that an empty list is possible and should not confuse your program! After displaying directions to the console, use GUI for the remaining input and output. Try out your program on the following lists:
10, 3, 8, 2, -99 (lo = 2)
-99 (ouput should be: "no numbers, no lo")
4, 6, 1, 106, 22, -99 (lo = 1)
So far, I've established that...
loop, probably do/while
get input from user, input
if input != "-99",
set list[i] (array) = input
if input == "-99"
set list[i] = input (makes it easy to terminate your loop through the array and to tell if it is otherwise emtpy)
sort through array, comparing two elements of the array, keep lowest and compare to next available, till -99 found
print as necessary
- This is what my friend has told me so far, but I'm not sure what he means by 'set list[i] (array) = unput.
Please help! Either respond here or my screen name (AIM) is Bionix12

Here's what I've got so far:
import javax.swing.JOptionPane;
public class IO {
     public static void main(String[]args){
          String dataString =
          JOptionPane.showInputDialog(null,
          "Enter an int value",
          "IO",
          JOptionPane.QUESTION_MESSAGE);
          int data = Integer.parseInt(dataString);
          int min = data;          
          do {
               dataString = JOptionPane.showInputDialog(null,
               "Enter an int value: \n (the program exits if the input is -99)",
               "IO",
               JOptionPane.QUESTION_MESSAGE);
               data = Integer.parseInt(dataString);
                    if (data != -99 && data > min){
                    min = data
          while (number != -99) {
               JOptionPane.showMessageDialog(null,
               "The min value is " + data,
               "IO",
               JOptionPane.INFORMATION_MESSAGE);
}
