Thread: Java Swing

So I just began learning java last week and am starting to learn swing and GUI creation today when I ran into a problem. The below code worked for a while and then suddenly the panels stopped displaying and I can't seem to figure out why. Currently when you run the script it displays an empty box in the center of the screen. Was hoping some of you experts could help a beginner out as it seems like such a simple task...


GUI.java:

package Armory;
 
import java.awt.GridLayout;
import java.awt.Dimension;
import java.awt.GraphicsEnvironment;
import java.awt.Point;
 
import javax.swing.BorderFactory;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.SwingConstants;
 
public class GUI extends JFrame {	
	public static void informationGUI() {
		// Set up frames/panels and center frame.
		JFrame frame = new JFrame("Character Information");
		JPanel container = new JPanel();
		JPanel cPanel = new JPanel();
		JPanel sPanel = new JPanel();
		JPanel bPanel= new JPanel();
		Point center = GraphicsEnvironment.getLocalGraphicsEnvironment().getCenterPoint();
		int width = 400;
		int height = 150;
		frame.setBounds(center.x - width / 2, center.y - height / 2, width, height);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setResizable(false);	
 
		// Set up all labels/buttons/text fields.
		JLabel cName = new JLabel("Character Name:", SwingConstants.RIGHT);
		JLabel cServer = new JLabel("Character Server:", SwingConstants.RIGHT);
		cName.setPreferredSize(new Dimension(115,20));
		cServer.setPreferredSize(new Dimension(115, 20));		
		JTextField cNameTF = new JTextField(15);
		JTextField cServerTF = new JTextField(15);
		JButton retrieve = new JButton("Retrieve");
		JButton cancel = new JButton("Cancel");
 
		// Add labels/Text Fields to cPanel
		cPanel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
		cPanel.add(cName);		
		cPanel.add(cNameTF);
 
		// Add labels/Text Fields to sPanel
		sPanel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
		sPanel.add(cServer);
		sPanel.add(cServerTF);
 
		// Add buttons to bPanel
		bPanel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
		bPanel.add(retrieve);
		bPanel.add(cancel);
 
		// Add all panels to main container panel and display frame.
		container.setLayout(new BoxLayout(container, BoxLayout.Y_AXIS));
		container.add(cPanel);
		container.add(sPanel);
		container.add(bPanel);
		frame.setVisible(true);
	}
}

Entry.java

package Armory;
 
public class Entry {
	public static void main(String args[]) {
		new GUI();
		GUI.informationGUI();
	}
}

Thanks for taking the time to look at this for me.

Thank you for the quick response.

a) great information, works like a charm.
b) whoops ;p Only gui I've ever created was in C# with the VB IDE so not use to having to add all these panels and then listeners and actions and so forth...


Again thank you for your help.
