(adsbygoogle = window.adsbygoogle || []).push({}); So after I got the GUI figured out, I decided to clean my computer a 'lil, by organization. So I installed the JDK 7, JFK 2.0 SDK, the JRE, and Eclipse on my flash drive. In doing so, I deleted my prior project without backing it up. Starting from scratch I figured "I'll make a new one. Gotta practice anyways." So I did, and now I can't get any of the buttons or text areas on the form. I've added them and the panels they've been added to. I'll list the code below and see if you guys can help.
I have kept it quite organized and neat which will allow me to add quite a bit more in the future if I want to, all thanks to multiple classes.

Main.java (Can't run without a main class can ya?)

    

public class Main {





    public static void main(String[] args) {

        // Create class objects

        Generate genObj = new Generate();

        GUI gui = new GUI();





        // Initialize the GUI

        gui.GUI();

        // Print out generated number by calling the "Generate" class

        System.out.println(Integer.toString(genObj.genRan()));

    }





}

Generate.java (Contains all the stuff having to do with generating the number

    

import java.util.Random;





public class Generate {





    public int genRan() {

        // Create Random variable "rand"

        Random rand = new Random();

        // Assign "result" the value of "rand" to the next generated integer

        int result = rand.nextInt();





        // Generate the number and print it out 

        for (int i = 0; i <= 0; i++) {

            result = rand.nextInt();

            System.out.println("Working...\nNumber generated.");

        }

        return result;

    }

}

And last but not least: GUI.java (Contains all the GUI stuff)

    

import javax.swing.*;

import java.awt.*;





public class GUI {





    private static final String TITLE = "Randomized Number";

    private static final int WIDTH = 400;

    private static final int HEIGHT = 300;

    private final String INSIDETITLE = "Testing";

    private final String genNumLabel = "Generated Number: ";

    

    

    public void GUI() {

        // Class objects

        Generate genObj = new Generate();

        

        // Frame options

        JFrame frame = new JFrame(TITLE);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.setSize(WIDTH, HEIGHT);

        frame.setLocationRelativeTo(null);

        frame.setResizable(false);

        frame.setVisible(true);





        // Initialize the buttons.

        JButton btnGen = new JButton("Generate");

        JButton btnExit = new JButton("EXIT");

        JButton btnCopy = new JButton("Copy");





        // Initialize the text areas.

        JTextArea generatedNum = new JTextArea(genNumLabel);

        JLabel theTitle = new JLabel(INSIDETITLE);





        // Initialize panels

        JPanel textArea = new JPanel();

        JPanel btnsArea = new JPanel();





        // Panel options





        // Add the components to the panels

        textArea.add(generatedNum);

        textArea.add(theTitle);





        btnsArea.add(btnGen);

        btnsArea.add(btnExit);

        btnsArea.add(btnCopy);





        // Add the panels to the frame

        frame.add(textArea);

        frame.add(btnsArea);

    }

}

PS. I'm getting more proficient in Java so don't hesitate to ask for help from me, even though I'm asking you for help right now.
PPS. I've also decided to stick with Java and learn it all the way through to adulthood. I think it'll be a good career choice for me, considering I LOVE Java and plan to possibly get a job in which I get to use it all day err'day.

Just add:

    frame.setVisible(true);

At the very bottom of your GUI method for your GUI class.

Oh, and you're still missing some button functionality.

Oh and off the GUI lines, I don't understand your "generate script", you seem to have a loop that would never even start. :p

All you need is this to have the same functionality & return.

    

public class Generate {

    public int genRan() {

        //Create Random variable "rand"

        Random rand = new Random();

		//Assign value

		int result = rand.nextInt();

		//Return

        return result;

    }

}

Or he could simply do:

    

public class Generate {

    public int genRan() {

        return new Random().nextInt();

    }

}

/facepalm on my part.

Or he could just not have it as a return in the first place, nothing is good enough for you is it. :\

Hey hey hey now. Gotta give the guy credit. He is really good at this and what's wrong with showing me something different?

And I know I'm missing stuff. I just wanted to get the current stuff done before moving on.

I'm friends with the guy (He's only 15) and he means well (By that I mean we're admins together. Dead forum, but still.). I love reading his tutorials and receiving his help. He's really a great programmer who has more knowledge than most (including me, I'm quite stupid). I just think that he takes things a bit further than us. He has a bigger interest in computer science than a lot of other people I've met. I really don't think he's intentionally being arrogant, but there's nothing wrong with flaunting his knowledge. He takes things more seriously too, which can get a wee bit annoying (not British). Just listen to him and accept what has been given to you. Think about how nooby we'd all be if there weren't people like him posting tutorials and correcting you.

Here's my full and honest opinion. I'm really trying to avoid conflict.

He's just trying to help. I honestly love the detail he gives. Here's an example: If your playing Football (American style, duh), and your only told what you've done wrong and how to fix it, you don't know the reasoning behind it. Coach "Go tackle that guy" Me *runs and tackles too high* Coach "Wrong. Hit 'em low at the legs" Me *runs and tackles legs* Coach "Know why that works? Knocking his legs out form underneath him prevents him from running. Meaning he gets less yards than when you hit 'em too high" What I'm saying is, you learn more behind it so you can understand how it works better. This is the way ADD's like me learn.

You make a good point there...
