Button size doesn't work.

[rokit boy]

My code:

package org.tests.Test1;

import javax.swing.*;
//import java.awt.*; 
import java.awt.Dimension;
import java.awt.event.*;

public class Test extends JFrame implements ActionListener{
	
	public Test(){
		setDefaultLookAndFeelDecorated(true);
		setSize(600,400);
		setTitle("Admin Controls");
		JButton startButton = new JButton("Start");
		startButton.setPreferredSize(new Dimension(40,40));
		startButton.addActionListener(this);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		setVisible(true);
		add(startButton);
	}
	
	public static void main(String args[]) {
		String password;
		password = JOptionPane.showInputDialog(null, "Password: ","Admin Conrol",JOptionPane.PLAIN_MESSAGE);
		if (password.equals("hi")) {
			new Test();
		} else {
			JOptionPane.showMessageDialog(null, "Wrong Password", "ERROR", JOptionPane.ERROR_MESSAGE);
		}
	}

	public void actionPerformed(ActionEvent e) {
		System.out.print("Hi");
	}
	

}

I'm a noob in Java so bare with me if there is any noobish mistakes, everytime I load up the frame, the button fills the whole screen!
Any help?

Go through Lesson: Laying Out Components Within a Container (The Java™ Tutorials > Creating a GUI With JFC/Swing) The default layout for a JFrame's contentPane is a BorderLayout.

Heck, go through the whole shebang or you're forever going to be asking here. Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

Thanks for the links, I chose the layout null and it worked! Thanks!

That's a very bad approach. You may get away with it for a layout with just a few components, run on only one computer, but it's better that you learn to use layouts effectively sooner rather than later.

If you're smart, then you'll move on sooner rather than "one day".

I'm not smart :P
I do know lua, Batch, C++ and python plus learning Java, but I guess the three apart from C++ and Java are pretty much useless.
