这是我的代码:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Test{
static CardLayout cardLayout;
static JPanel card = new JPanel();
public static void main(String[] args) {
JFrame frame = new JFrame("AddressBook");
JPanel contentPane = (JPanel)frame.getContentPane();
card.setLayout(cardLayout = new CardLayout());
JPanel cardTop = new JPanel();
DefaultTableModel model = new DefaultTableModel();
model.addColumn("Name");
model.addColumn("Number");
String[] John = {"John", "1234"};
model.addRow(John);
String[] Beth = {"Beth", "4444"};
model.addRow(John);
JTable table = new JTable(model);
JScrollPane jsp = new JScrollPane(table);
cardTop.add(jsp);
card.add("Card Top", cardTop);
contentPane.add(card);
frame.setVisible(true);
frame.setSize(507, 191);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
}
}
当我尝试编译时,它说它无法识别 DefaultTableModel。此外,上面的代码是我的主要代码的一部分,我确信我已经导入了正确的库。
这是错误:
Test.java:15: error: cannot find symbol
DefaultTableModel model = new DefaultTableModel();
^
symbol: class DefaultTableModel
location: class Test
Test.java:15: error: cannot find symbol
DefaultTableModel model = new DefaultTableModel();
^
symbol: class DefaultTableModel
location: class Test
2 errors
请帮忙?
