Question

我正在使用Swing开发酒店预订应用程序。

我有一个JTable行的房间列表。如果我点击任何一行，那么如果用户为特定日期预订了该房间，则所选房间将进入预订。之后如果有人试图为相同的日期预订同一个房间，它必须显示警告信息或如何从表中隐藏该行？

import javax.swing.*;
/**

 * @author ssn
 */
public class Reservation extends javax.swing.JFrame {

    /**
     * Creates new form Reservation
     */
    public Reservation() {
        initComponents();
    }
    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
     */
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {

        jPanel2 = new javax.swing.JPanel();
        jPanel1 = new javax.swing.JPanel();
        jLabel2 = new javax.swing.JLabel();
        jLabel3 = new javax.swing.JLabel();
        jLabel4 = new javax.swing.JLabel();
        RentPerDay = new javax.swing.JTextField();
        BedType = new javax.swing.JTextField();
        RoomNo = new javax.swing.JTextField();
        RoomType = new javax.swing.JTextField();
        jLabel5 = new javax.swing.JLabel();
        jLabel6 = new javax.swing.JLabel();
        jLabel7 = new javax.swing.JLabel();
        jLabel8 = new javax.swing.JLabel();
        jLabel9 = new javax.swing.JLabel();
        jLabel10 = new javax.swing.JLabel();
        jLabel11 = new javax.swing.JLabel();
        jButton1 = new javax.swing.JButton();
        jLabel12 = new javax.swing.JLabel();
        jLabel13 = new javax.swing.JLabel();
        jLabel14 = new javax.swing.JLabel();
        jLabel15 = new javax.swing.JLabel();
        jLabel16 = new javax.swing.JLabel();
        jLabel17 = new javax.swing.JLabel();
        jButton2 = new javax.swing.JButton();
        jTextField1 = new javax.swing.JTextField();
        jTextField2 = new javax.swing.JTextField();
        jTextField3 = new javax.swing.JTextField();
        jTextField7 = new javax.swing.JTextField();
        jTextField8 = new javax.swing.JTextField();
        jTextField9 = new javax.swing.JTextField();
        NoOfdays = new javax.swing.JTextField();
        jTextField11 = new javax.swing.JTextField();
        jComboBox1 = new javax.swing.JComboBox<>();
        jComboBox2 = new javax.swing.JComboBox<>();
        jComboBox3 = new javax.swing.JComboBox<>();
        jLabel1 = new javax.swing.JLabel();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jPanel2.setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

        jPanel1.setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

        jLabel2.setText("RESERVATION OF ROOM");
        jPanel1.add(jLabel2, new org.netbeans.lib.awtextra.AbsoluteConstraints(0, 0, 800, 20));

你不关心编码，只是分享我是怎么做的

在JTable使用中为行选择创建侦听器：

yourJTable.getSelectionModel().addListSelectionListener(e -> {
     public void valueChanged(ListSelectionEvent e) {
          ListSelectionModel lsm = (ListSelectionModel) e.getSource();
     }
});

在此听众中，您可以检查是否已预订选定的房间并将其发送至预订。

要隐藏JTable行，您应按照in the tutorial所述使用过滤。

如果选择其中一行，如何在JTable中显示其他行？
