1.创建一个随机点名的类

  1  public class ProcessRandomName {
  2      
  3          JFrame rFrame;
  4          JLabel name;
  5          JButton btn;
  6          Random rd;
  7      
  8          ArrayList<String> nameList = new ArrayList<>();
  9      
 10          public ProcessRandomName() {
 11              rFrame = new JFrame("随机点名");
 12              name = new JLabel();
 13              btn = new JButton("开始点名");
 14              rd = new Random();
 15          }
 16      
 17          public void init() {
 18              SetName(nameList);
 19              JLabel jLabel = new JLabel("随机点名器");
 20              jLabel.setHorizontalAlignment(0);
 21              jLabel.setFont(new Font("开始点名了", 0, 35));
 22              
 23              name.setHorizontalAlignment(0);
 24              btn.addActionListener(new ActionListener() {
 25      
 26                  final ProcessRandomName this$0;
 27      
 28                  public void actionPerformed(ActionEvent paramActionEvent) {
 29                      String curindex = getRandomName();
 30                      name.setText(curindex);
 31                      name.setFont(new Font(curindex, 0, 35));
 32                      name.setForeground(Color.red);
 33                  }
 34      
 35                  {
 36                      this$0 = ProcessRandomName.this;
 37      //                super();
 38                  }
 39              });
 40      
 41              Container p = rFrame.getContentPane();
 42              p.setLayout(new BorderLayout(3, 1));
 43              p.add(jLabel, "North");
 44              p.add(name, "Center");
 45              p.add(btn, "South");
 46      //        p.setBackground(Color.black);
 47              
 48              rFrame.pack();
 49              rFrame.setVisible(true);
 50              rFrame.setSize(300,300);
 51              rFrame.setDefaultCloseOperation(0);
 52              rFrame.setResizable(true);
 53              rFrame.setLocationRelativeTo(null);
 54              rFrame.addWindowListener(new WindowListener() {
 55                  
 56                  @Override
 57                  public void windowOpened(WindowEvent paramWindowEvent) {
 58                      paramWindowEvent.getComponent();
 59                      rFrame.isShowing();
 60                  }
 61                  
 62                  @Override
 63                  public void windowIconified(WindowEvent paramWindowEvent) {
 64                      // TODO Auto-generated method stub
 65                      
 66                  }
 67                  
 68                  @Override
 69                  public void windowDeiconified(WindowEvent paramWindowEvent) {
 70                      // TODO Auto-generated method stub
 71                      
 72                  }
 73                  
 74                  @Override
 75                  public void windowDeactivated(WindowEvent paramWindowEvent) {
 76                      // TODO Auto-generated method stub
 77                      
 78                  }
 79                  
 80                  @Override
 81                  public void windowClosing(WindowEvent paramWindowEvent) {
 82                      System.exit(0);
 83                  }
 84                  
 85                  @Override
 86                  public void windowClosed(WindowEvent paramWindowEvent) {
 87                      // TODO Auto-generated method stub
 88                      
 89                  }
 90                  
 91                  @Override
 92                  public void windowActivated(WindowEvent paramWindowEvent) {
 93                      // TODO Auto-generated method stub
 94                      
 95                  }
 96              });
 97          }
 98      
 99          public void SetName(ArrayList<String> nameList) {
100              nameList.add("张三");
101              nameList.add("李四");
102              nameList.add("王五");
103              nameList.add("代雪");
104     
105          }
106      
107          public String getRandomName() {
108              int index = 1;
109              index = rd.nextInt(nameList.size());
110              String nameIndex= nameList.get(index);
111              return nameIndex;
112          }
113      }

 

 

2.创建一个运行的类

1 public static void main(String[] args) {
2         ProcessRandomName test =  new ProcessRandomName();
3         test.init();
4         
5  }

 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！
