This is a help section. Not a do-it-for-you-so-that-you-don't-have-to-and-will-never-learn-that-way section. Adding listeners is quite easy =)

ok fair enough, could you help me out with a few links or examples to using the math.random function. i am using netbeans. my instructor said i must use textpad...but he still lives in the prehistoric age.

i basically need to implement, math.random then generate random numbers in individual text fields, the user with the highest value wins.

im a technician/network engineer..not a coder.

You change a text fields value using the .setText(<string>) method. As for a random, do you want it to be in a range, or just some number?

thnx for the help :-)

i want it to do a math.random of values between 0(or)1 and 50 (so in essence a range of int's) then print them to indivdual boxes...is there a way i can link multiple objects to work on one array, so i can tell it

math.random (init function of random numbers)
while
(print text to (textboxset1.setText(math.random output));

cuz it will be a b**ch if i have to code for each individual box.

i am using net beans as my builder...then copy paste to textpad to see if it will run.

ok here is screen shot of my app (for some reason it wont display the pic..here is direct code to pic)

Code:
http://i272.photobucket.com/albums/jj191/EldHawke/applet.jpg




and here is my code
Code:
public class applet extends java.applet.Applet {
    
    /** Initializes the applet appplet */

            });

Use an ArrayList
You can add all the text boxes into an ArrayList and then use a loop to accomplish your task.
