How to create a GUI in Java [closed]

Question

I have used Java for some time, but I have never created a GUI - always CLI. How does one create a GUI in Java? Can you suggest a good tutorial/reference?

I'm looking to create a simple GUI that has two long text areas and some buttons.

Answer 1

Here's a simple example

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextArea;

public class Foo{

  public static void main(String[] args) {

    JFrame f = new JFrame("A JFrame");
    f.setSize(250, 250);
    f.setLocation(300,200);
    final JTextArea textArea = new JTextArea(10, 40);
    f.getContentPane().add(BorderLayout.CENTER, textArea);
    final JButton button = new JButton("Click Me");
    f.getContentPane().add(BorderLayout.SOUTH, button);
    button.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            textArea.append("Button was clicked\n");

        }
    });

    f.setVisible(true);

  }

}
