Here is my code:

Code:

package GUI;

import java.awt.event.*;
import javax.swing.*;
import Core.Glass;
import GUI.*;
public class Actions implements ActionListener {
	
	public void actionPerformed(ActionEvent e) {
		
		Build build = new Build();
		
		String actionCommand = e.getActionCommand();
		
		String word = build.JTF.getText();
		if (actionCommand.equals("Enter")) {
			JOptionPane.showMessageDialog(null, word);
		}

	}
}

I don't see anything wrong with it, how come i can't see my code? Maybe it's thinking JTF is a method? That shouldn't be, when JTF is the textfield and it's grabbing text from it.

Here is my build class:

Code:


package GUI;

import java.awt.*;
import javax.swing.*;
import GUI.*;
import Core.Glass;
public class Build extends JFrame {
	
	private final int width = 250;
	private final int height = 350;
	JPanel panel1 = new JPanel();
	JButton button1 = new JButton();
	JLabel label1 = new JLabel();
	JTextField JTF = new JTextField();
	
	/**
	 * Creats a new JFrame.
	 */
	 
	public void newFrame() {
		
		// Sets the windows title.
		setTitle("TEST");
		
		// Sets the windows size.
		setSize(width,height);
		
		// Sets the windows default closing operation.
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		// Sets the window default layout.
	//	setBorderLayout(new BorderFactory())
	
		// Calls buildPanel Method.
		buildPanel();
		
		
		
		// Sets the window visible.
		setVisible(true);
				// JLabel.
		label1 = new JLabel("Please enter in your name");
		
		// JTextField.
		JTF = new JTextField(10);
		
		// JButton.
		button1 = new JButton("Enter");
		button1.addActionListener(new Actions());
		
		// JPanel.
		panel1 = new JPanel();
		
		// Adds components to JPanel.
		panel1.add(label1);
		panel1.add(JTF);
		panel1.add(button1);
		add(panel1);
	}
	
	/**
	 * Builds the components for the JFrame.
	 */
	 
	public void buildPanel() {
		

	}
	
}

I put everything into one method just to test, I know it's sloppy.

lolol, how do you except it to show when the parentComponent is set to null?

set the parentComponent to the instance of Build:

Code:

if (actionCommand.equals("Enter"))
    JOptionPane.showMessageDialog(build, word);

you have to declare JOptionPane as null.

no you dont.
you have to pass the parent component, which in this case is your 'build' frame..

Just means that it's independent, it doesn't need a parent component.

Code:

package GUI;

import javax.swing.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

public class Frame extends JFrame {
    JPanel panel1 = new JPanel();
    JButton button1 = new JButton();
    JLabel label1 = new JLabel();
    JTextField JTF = new JTextField();

    public static void main(String[] args) {
        new Frame().setVisible(true);
    }
    public Frame() {

        final int width = 250;
        final int height = 350;

        // Sets the windows title.
        setTitle("TEST");

        // Sets the windows size.
        setSize(width,height);

        // Sets the windows default closing operation.
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // Sets the window default layout.
        //	setBorderLayout(new BorderFactory())

        // JLabel.
        label1 = new JLabel("Please enter in your name");

        // JTextField.
        JTF = new JTextField(10);

        // JButton.
        button1 = new JButton("Enter");
        button1.addActionListener(new ActionHandler());

        // JPanel.
        panel1 = new JPanel();

        // Adds components to JPanel.
        panel1.add(label1);
        panel1.add(JTF);
        panel1.add(button1);
        add(panel1);
    }
    class ActionHandler implements ActionListener {

        public void actionPerformed(ActionEvent e) {

            String actionCommand = e.getActionCommand();

            String word = JTF.getText();
            if (actionCommand.equals("Enter")) {
                JOptionPane.showMessageDialog(null, word);
            }
        }
    }
}

Fixed.
It's not tested but I know it will work.
