Thread: Adding 100 single digit numbers to a Text Field

Ok so I have been trying to figure this out with no luck whatsoever, I have tried multiple website, irc channel to no avail.

The problem is I cant find a way to recursivly add random generated numbers to a Text Field.

The script is going to be a 100 digit random number generator, this is what I currently have so far, any help would be greatly appreciated.

import java.util.Random;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JButton;
 
public class RandomNumber extends JFrame implements ActionListener {
 
	public JTextField textField;
	public JButton btnGenerate = new JButton("Generate");
 
	public String numbers = null;
	Random randomGenerator;
 
	public static void main(String[] args) {
		RandomNumber app = new RandomNumber();
	}
 
	public RandomNumber() {
		super("Number Generator");
		setSize(400, 120);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		getContentPane().setLayout(null);
 
		textField = new JTextField();
		textField.setBounds(10, 11, 364, 20);
		getContentPane().add(textField);
 
		btnGenerate.setBounds(150, 42, 100, 23);
		getContentPane().add(btnGenerate);
		btnGenerate.addActionListener(this);
 
		setVisible(true);
	}
 
	public void actionPerformed(ActionEvent e) {
		if (e.getSource() == btnGenerate) {
			for (int x = 0; x < 100; x++) {
				int num = randomGenerator.nextInt(10);
				//this is were I'm having troubles
			}
		}
	}
}

I solved it

import java.util.Random;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JButton;
 
public class RandomNumber extends JFrame implements ActionListener {
 
	public JTextField textField;
	public JButton btnGenerate = new JButton("Generate");
	int rndoutcome = 0;
	public String numbers;
	Random randomGenerator;
 
	public static void main(String[] args) {
		RandomNumber app = new RandomNumber();
	}
 
	public RandomNumber() {
		super("Number Generator");
		setSize(400, 112);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		getContentPane().setLayout(null);
 
		textField = new JTextField();
		textField.setBounds(10, 11, 364, 20);
		getContentPane().add(textField);
 
		btnGenerate.setBounds(150, 42, 100, 23);
		getContentPane().add(btnGenerate);
		btnGenerate.addActionListener(this);
 
		setVisible(true);
	}
 
	public void actionPerformed(ActionEvent e) {
		if (e.getSource() == btnGenerate) {
			textField.setText(null);
			for (int x = 0; x <= 100; x++) {
				try {
					rndoutcome = (int) (Math.random() * 10);
					numbers = (textField.getText());
					textField.setText(numbers + rndoutcome);
				} catch (NullPointerException a) {
					System.out.println(a.getMessage());
				}
			}
		}
	}
