Java JFrame视图

绝地灬酷狼 2022-04-13 11:49 279阅读 0赞

这是我用java+可视化工具(Eclipse)写的，具体底层不再解释，代码直接演示使用方法

将此段代码放置在main中

  1. JFrame jframe = new JFrame("MD5加密工具");//里面是名字
  2. jframe.getContentPane().add(new JavaMD5());//添加视图
  3. jframe.setSize(460, 450);// 窗口大小
  4. jframe.setResizable(false);//设置为不可调整大小
  5. jframe.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);//设置关闭方式
  6. jframe.setVisible(true);//设置为显示

下面是一些视图

  1. public class JavaMD5 extends JPanel {
  2.     /**
  3.      * 
  4.      */
  5.     private static final long serialVersionUID = 1L;
  6.     private JTextField textField;
  7.     private static TextArea textArea;
  8.     private static JComboBox comboBox;
  10.     /**
  11.      * Create the panel.
  12.      */
  13.     public JavaMD5() {
  14.         setBackground(UIManager.getColor("CheckBox.light"));
  15.         setLayout(null);
  17.         JLabel lblMd = new JLabel("MD5\u52A0\u5BC6\u5DE5\u5177");
  18.         lblMd.setForeground(new Color(0, 0, 0));
  19.         lblMd.setFont(new Font("微软雅黑", Font.PLAIN, 14));
  20.         lblMd.setBounds(191, 10, 131, 15);
  21.         add(lblMd);
  23.         JLabel label = new JLabel("\u8F93\u5165\u52A0\u5BC6\u6587\u672C:");
  24.         label.setForeground(new Color(0, 0, 0));
  25.         label.setFont(new Font("微软雅黑", Font.PLAIN, 12));
  26.         label.setBounds(32, 48, 84, 32);
  27.         add(label);
  29.         textField = new JTextField();
  30.         textField.setEditable(false);
  31.         textField.setBounds(126, 276, 282, 26);
  32.         add(textField);
  33.         textField.setColumns(10);
  35.         JButton button = new JButton("\u52A0\u5BC6");
  36.         button.addActionListener(new ActionListener() {
  37.             public void actionPerformed(ActionEvent arg0) {
  38.                 // 加密事件
  39.                 String original = textArea.getText();
  41.                 if ((original.trim()).length() > 0) {

  43.                         MessageDigest md5 = MessageDigest.getInstance("MD5");
  44.                         md5.update(original.getBytes("utf-8"));
