    Default need numbers to output onto a new line

    hay guy...I'm having trouble with some code using an applet. I'm outputting a messgae asking a user to ener 4 number. When the numbers are entered and the user selects ok. An inforamtion messgae of the numbers entered will appear on the screen...now i have that part done but what if i want the numbers to be entered into a new line. In c++ you just enter \n. This doesn't work in this case.
    Example:
    user entered 1234
    I want 1
    2
    3
    4
    to be outputed on my information box

    */import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
     
    /**
    *
    * 
    */
    public class NewJApplet extends javax.swing.JApplet {
     
    String number1;
     
     
    /** Creates a new instance of NewJApplet */
    public NewJApplet() {
    number1=JOptionPane.showInputDialog(null,"Please Enter Four Digits.",
    JOptionPane.QUESTION_MESSAGE); 
     
    JOptionPane.showMessageDialog(null,"The numbers you typed are.\n"+ number1+"\n"); 
     
    }
     
    }


    Any help would be great!!

    hi . first please put your codes on highlight tags >> [highlight=java] code [/highlight]

    you cant print those individualy EACH line.. because your String object(Variable) is a WHOLE string.
    so when you enter, say, 1234 , the number1 does not contain individual strings.. its a one whole intact STRING
    , when you wrote this statement >
    "The Numbers you typed are. "\n" + number1 + "\n",
    its like your telling java ok print a NewLine("\n) and print the values of number1 and print another NewLine "\n"
    you need to get each one of it.. and assign it individually into another STRING object and adding a new line

    ill provide the logic of the loop for you .
    for (int x = 0; x <= number1.length() - 1; x++) {
     
            eachNumber = eachNumber + ("" + "\n" + number1.charAt(x));
     
        }

    where eachNumber increments everytime it gets the value on your STRING Object number1 and adds a "\n" which is a new line, now go ahead how are you goint to print all the value of eachNumber object.

    sorry for bad english .. im a bit tired
