第六次java作业

1、制作一个如图所示的界面（使用FlowLayout布局），不要求实现功能。（图略）

程序如下：

package WindowBuilder;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.EmptyBorder;
import java.util.Date;
import java.awt.Window.Type;
import java.awt.Dialog.ModalExclusionType;

public class MyClock extends JFrame {

    private JPanel contentPane;
    private JTextField textField;
    private JTextField textField_1;
    private JTextField textField_2;
    private JTextField textField_3;
    private JTextField textField_4;
    private JTextField textField_5;
    Date date=new Date();
    String s1=String.format("%tH", date);
    String s2=String.format("%tM", date);
    String s3=String.format("%tS", date);
    public static void main(String[] args) 
    {
        EventQueue.invokeLater(new Runnable() 
        {
            public void run() {
                try {
                    MyClock frame = new MyClock();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    /**
     * Create the frame.
     */
    public MyClock() {
        setBackground(Color.GREEN);
        setAlwaysOnTop(true);
        setModalExclusionType(ModalExclusionType.TOOLKIT_EXCLUDE);
        setType(Type.UTILITY);
        setForeground(Color.GREEN);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 359, 337);
        contentPane = new JPanel();
        contentPane.setForeground(Color.GREEN);
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));
        
        JLabel label = new JLabel("\u5F53\u524D\u65F6\u95F4\uFF1A");
        contentPane.add(label);
        
        textField = new JTextField();
        textField.setEditable(false);
        textField.setHorizontalAlignment(SwingConstants.CENTER);
        contentPane.add(textField); 
        textField.setColumns(5);
        textField.setText(s1);
        
        JLabel label_1 = new JLabel("\u65F6");
        contentPane.add(label_1);
        
        textField_1 = new JTextField();
        textField_1.setEditable(false);
        textField_1.setHorizontalAlignment(SwingConstants.CENTER);
        contentPane.add(textField_1);
        textField_1.setColumns(5);
        textField_1.setText(s2);
        
        JLabel label_2 = new JLabel("\u5206");
        contentPane.add(label_2);
        
        textField_2 = new JTextField();
        textField_2.setEditable(false);
        textField_2.setHorizontalAlignment(SwingConstants.CENTER);
        contentPane.add(textField_2);
        textField_2.setColumns(5);
        textField_2.setText(s3);
        
        JLabel label_3 = new JLabel("\u79D2");
        contentPane.add(label_3);
        
        JLabel label_5 = new JLabel("\u95F9\u949F\u65F6\u95F4\uFF1A");
        contentPane.add(label_5);
        
        textField_3 = new JTextField();
        contentPane.add(textField_3);
        textField_3.setColumns(5);
        
        JLabel label_6 = new JLabel("\u65F6");
        contentPane.add(label_6);
        
        textField_4 = new JTextField();
        contentPane.add(textField_4);
        textField_4.setColumns(5);
        
        JLabel label_7 = new JLabel("\u5206");
        contentPane.add(label_7);
        
        textField_5 = new JTextField();
        contentPane.add(textField_5);
        textField_5.setColumns(5);
        
        JLabel label_8 = new JLabel("\u79D2");
        contentPane.add(label_8);
        
        JLabel label_9 = new JLabel("\u95F9\u949F\u8BBE\u7F6E\uFF1A");
        contentPane.add(label_9);
        
        JButton button = new JButton("\u5F00");
        contentPane.add(button);
        
        JButton button_1 = new JButton("\u5173");
        contentPane.add(button_1);
        
        JLabel label_4 = new JLabel("");
        contentPane.add(label_4);
    }

}

运行结果如下：

2、设计一个用标签、文本行与按钮来登录的界面（用GridLayout布局方式）。如图所示。（图略）

程序如下：

package WindowBuilder;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.EmptyBorder;

public class Identfiant extends JFrame {

    private JPanel contentPane;
    private JTextField textField;
    private JPasswordField passwordField;
    public static void main(String[] args) 
    {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    Identfiant frame = new Identfiant();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }
    public Identfiant() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(new GridLayout(2, 1, 0, 0));
        
        JPanel panel = new JPanel();
        contentPane.add(panel);
        panel.setLayout(new GridLayout(2, 2, 0, 0));
        
        JLabel label = new JLabel("\u7528\u6237\u540D\uFF1A");
        label.setHorizontalAlignment(SwingConstants.CENTER);
        panel.add(label);
        
        textField = new JTextField();
        panel.add(textField);
        textField.setColumns(10);
        
        JLabel label_1 = new JLabel("\u53E3\u4EE4\uFF1A");
        label_1.setHorizontalAlignment(SwingConstants.CENTER);
        panel.add(label_1);
        
        passwordField = new JPasswordField();
        panel.add(passwordField);
        
        JPanel panel_1 = new JPanel();
        contentPane.add(panel_1);
        panel_1.setLayout(null);
        
        JButton button = new JButton("\u786E\u5B9A");
        button.setBounds(0, 55, 207, 61);
        panel_1.add(button);
        
        JButton button_1 = new JButton("\u53D6\u6D88");
        button_1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
            }
        });
        button_1.setBounds(217, 56, 197, 60);
        panel_1.add(button_1);
    }

}

运行结果如下：
