 3         Student s1 = new Student("张三", "001", 0);
 4         Student s2 = new Student("李四", "002", 1);
 5         Student s3 = new Student("王五", "003", 0);

 7         Vector<Object> row1 = new Vector<Object>();
 8         row1.add(s1.getName());
 9         row1.add(s1.getNumber());
10         row1.add(s1.getAbsentTimes());
11 
12         Vector<Object> row2 = new Vector<Object>();
13         row2.add(s2.getName());
14         row2.add(s2.getNumber());
15         row2.add(s2.getAbsentTimes());
16 
17         Vector<Vector<Object>> studentData = new Vector<Vector<Object>>();
18         Vector<String> columnNames = new Vector<String>();
19 
20         studentData.add(row1);
21         studentData.add(row2);
22 
23         columnNames.add("姓名");
24         columnNames.add("编号");
25         columnNames.add("缺考次数");
26 
27         JTable table = new JTable(studentData, columnNames);
28 
29         JFrame f = new JFrame();
30 
31         JScrollPane scrollPane = new JScrollPane(table);
32         f.getContentPane().add(scrollPane, BorderLayout.CENTER);
33         f.setVisible(true);
34         f.setSize(500, 500);
35         f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
