    Default Can anyone help me finish creating a GUI for my program

    Hi, I am doing a program for class, heres what it asks to give you a background information- Use a one-dimensional array to solve the following problem: Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if it's not a duplicate of a number already read. Provide for the "worst case" in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value. Use a GUI with a textfield to enter each value and a text area to display the unique values. - here is what I have so far,
    FIRST CLASS-

    public class Numbs
    {
       public static void main( String[] args )
         {
           Numbers obj = new Numbers();
           obj.getNumbers();
         } 
    }
    SECOND CLASS-
    public class Numbers 
    {
    public void getNumbers() {
      Scanner input = new Scanner(System.in);
        int[] array = new int[5];
     
        int count = 0;
        int entered = 0;
        int num = 0;
     
        while (entered < array.length) 
            {
            System.out.println("Enter numbers: ");
            num = input.nextInt();
     
            if ((num >= 10) && (num <= 100)) {
                boolean containsNumber = false;
                entered++;
     
                for (int i = 0; i < array.length; i++) 
                {  
                if (array[i] == num)       
     
                containsNumber = true;
                }  
     
                if (!containsNumber) 
                {
                array[count] = num;
     
                count++;
                }
     
                else
     
                System.out.printf(" has already been entered\n", num);
     
                      }
     
              else
               System.out.println("numbers must range between 10 and 100");
     
     
            for (int i =0;  i< entered; i++) {
     
            System.out.print(array[i] + " ");
            }
     
                                      System.out.println();
        } 
    } 
    public void createGUI()
    {
            setDefaultCloseOperation(EXIT_ON_CLOSE);
            Container window = getContentPane();
            window.setLayout(new BorderLayout());
     
            controlPanel = new JPanel();
            controlPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
     
            textArea = new JTextArea();
            textArea.setBackground(Color.white);
     
    }
     
     public static void main(String args[])
        {
            UserInterface myApplication = new UserInterface();
        }
    }
    -Now the problem I am having is creating the GUI, everything works except for that and here it is saying cannont find symbol (EXIT_ON_CLOSE) and other than that I believe my GUI class is not finished, any help would be appreciated.

    Is this all of your code? There are quite a few errors.. For starters, you haven't imported anything.

    You need to do some more reading on creating a GUI - Lesson: Using Swing Components (The Java™ Tutorials > Creating a GUI With JFC/Swing)
    Please use [highlight=Java] code [/highlight] tags when posting your code.

    Atleast start creating the GUI in a way so that we could help you finishing your GUI :-)

    Default Re: Can anyone help me finish creating a GUI for my program

    this is my GUI for no duplication of one dimensional array ( in JaVa)
    i need you guys help and hint in order to complete the GUI
    basically on the JLabel the 5 numbers will be entered by the user
    JtextField will display the 5 numbers to the user and after hitting enter it will also display 5
    unique array numbers that is not the same as what the user entered.

    Display the complete set
    of unique values input after the user enters
    each new value.
    i Use a GUI with a text field to enter each value and a text area to display to numbers

    how to display the unique values?


    import javax.swing.*;

    public class GUI extends JFrame implements ActionListener{
     
    private JPanel panel, bottomPanel;

    private JButton btn1;     //add final button
    private JTextArea txaResults;    //display numbers

    // basically takes all the information and puts it into a grid format

    my other program class is my one dimensional array


    /** this is the main objective:

    * One dimensional array to set up the amount of numbers and return the average.
    * Use a one-dimensional array to solve the
    *following problem: Write an application
    *that inputs five numbers, each between 10
    *and 100, inclusive. As each number is read,
    *display it only if it's not a duplicate of a
    *number already read. Provide for the
    *"worst case" in which all five numbers are
    *different. Use the smallest possible array to
    *solve this problem. Display the complete set
    *of unique values input after the user enters
    *each new value.Use a GUI with a text field to enter each
    *value and a text area to display the unique values.

    basically my code should be displaying a non duplicate array to the user
    after he enters 5 numbers in a one dimensional array. the numbers each between 10 and 100 inclusively
    i think i need a binary search or a search, then maybe 2 loops
