1.创建一个随机点名的类

  public class ProcessRandomName {

          JFrame rFrame;

          JLabel name;

          JButton btn;

          Random rd;

          ArrayList<String> nameList = new ArrayList<>();

          public ProcessRandomName() {

              rFrame = new JFrame("随机点名");

              name = new JLabel();

              btn = new JButton("开始点名");

              rd = new Random();

          }

          public void init() {

              SetName(nameList);

              JLabel jLabel = new JLabel("随机点名器");

              jLabel.setHorizontalAlignment(0);

              jLabel.setFont(new Font("开始点名了", 0, 35));

              name.setHorizontalAlignment(0);

              btn.addActionListener(new ActionListener() {

                  final ProcessRandomName this$0;

                  public void actionPerformed(ActionEvent paramActionEvent) {

                      String curindex = getRandomName();

                      name.setText(curindex);

                      name.setFont(new Font(curindex, 0, 35));

                      name.setForeground(Color.red);

                  }

                  {

                      this$0 = ProcessRandomName.this;

      //                super();

                  }

              });

              Container p = rFrame.getContentPane();

              p.setLayout(new BorderLayout(3, 1));

              p.add(jLabel, "North");

              p.add(name, "Center");

              p.add(btn, "South");

      //        p.setBackground(Color.black);

              rFrame.pack();

              rFrame.setVisible(true);

              rFrame.setSize(300,300);

              rFrame.setDefaultCloseOperation(0);

              rFrame.setResizable(true);

              rFrame.setLocationRelativeTo(null);

              rFrame.addWindowListener(new WindowListener() {

                  @Override

                  public void windowOpened(WindowEvent paramWindowEvent) {

                      paramWindowEvent.getComponent();

                      rFrame.isShowing();

                  }

                  @Override

                  public void windowIconified(WindowEvent paramWindowEvent) {

                      // TODO Auto-generated method stub

                  }

                  @Override

                  public void windowDeiconified(WindowEvent paramWindowEvent) {

                      // TODO Auto-generated method stub

                  }

                  @Override

                  public void windowDeactivated(WindowEvent paramWindowEvent) {

                      // TODO Auto-generated method stub

                  }

                  @Override

                  public void windowClosing(WindowEvent paramWindowEvent) {

                      System.exit(0);

                  }

                  @Override

                  public void windowClosed(WindowEvent paramWindowEvent) {

                      // TODO Auto-generated method stub

                  }

                  @Override

                  public void windowActivated(WindowEvent paramWindowEvent) {

                      // TODO Auto-generated method stub

                  }

              });

          }

          public void SetName(ArrayList<String> nameList) {

              nameList.add("张三");

              nameList.add("李四");

              nameList.add("王五");

              nameList.add("代雪");

          }

          public String getRandomName() {

              int index = 1;

              index = rd.nextInt(nameList.size());

              String nameIndex= nameList.get(index);

              return nameIndex;

          }

      }

2.创建一个运行的类

 public static void main(String[] args) {

         ProcessRandomName test =  new ProcessRandomName();

         test.init();

  }

简单的做了以上两个步骤Ctrl+C，Ctrl+V就能创建一个随机点名的小程序，如果想要生成一个可运行的exe文件，请点击我！
