Java UI#

1. 创建一个Java类#

package fhc;

import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                JFrame jFrame = new MainFrame("Hello");
                jFrame.setSize(640, 480);
                jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                jFrame.setVisible(true);


            }
        });

    }

}

2.创建一个UI类继承自JFrame#

package fhc;

import javax.swing.JFrame;
import javax.swing.JButton;
import java.awt.BorderLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

public class MainFrame extends JFrame {

    /**
     * 
     */
    private static final long serialVersionUID = -4989400973301541581L;

    public MainFrame(String title){
        super(title);

        JButton btnNewButton = new JButton("Start");
        btnNewButton.setBounds(79, 107, 63, 65);
        btnNewButton.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                System.out.println("Start");
            }
        });
        getContentPane().setLayout(null);
        getContentPane().add(btnNewButton);

        JButton btnStop = new JButton("Stop");
        btnStop.setBounds(188, 107, 57, 65);
        btnStop.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                System.out.println("Stop");
            }
        });
        getContentPane().add(btnStop);
    }

}

3. 结果如下#
