单击按钮时如何将数组添加到Jtable java

Question

我有一个包含地址的数组，地址的第 1 行和第 2 行。

我想在单击 btn 时将数组添加到 Jtable。我已经阅读了文档，但我仍然没有得到它，请帮助我。

import java.awt.event.*;
import java.awt.EventQueue;

import javax.swing.*;

public class Driver extends Family {

    private JFrame f;
    private JPanel p;

    JButton btn1 = new JButton("Business Shipping");
    JButton btn2 = new JButton("Family Shipping");

    JLabel lbl1 = new JLabel("Business Name:");
    JLabel lbl2 = new JLabel("URL:");
    JLabel lbl3 = new JLabel("Professional Name");
    JLabel lbl4 = new JLabel("First Name:");
    JLabel lbl5 = new JLabel("Last Name:");
    JLabel lbl6 = new JLabel("Email:");
    JLabel lbl7 = new JLabel("Phone:");
    JLabel lbl8 = new JLabel("Relationship:");
    JLabel lbl9 = new JLabel("Answer Call:");

    JTextField jt1 = new JTextField(businessName);
    JTextField jt2 = new JTextField(website);
    JTextField jt3 = new JTextField (toString());
    JTextField jt4 = new JTextField(First());
    JTextField jt5 = new JTextField(Last());
    JTextField jt6 = new JTextField(Email());
    JTextField jt7 = new JTextField(Phone());
    JTextField jt8 = new JTextField(Relationship());
    String txt = Boolean.toString(AnswerCall(Relationship()));//converting boolean to string value
    JTextField jt9 = new JTextField(txt);
    JTable tbl1 = new JTable();



    public Driver () {      
        gui();      
    }
      btn1.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                btn1MouseClicked(evt);
                tbl1.setText(ShippingLabel(sl));                
            }
        });

    public void gui() { 
        f = new JFrame("Address Book");     
        p = new JPanel();   
        f.add(p);
        p.setLayout(null);

        p.add(btn1);
        p.add(btn2);

        p.add(tbl1);

        lbl8.setLocation(27, 160);
        lbl9.setLocation(27, 180);

        btn1.setLocation(27, 200);
        btn2.setLocation(27, 220);

        jt1.setLocation(223, 20);
        jt2.setLocation(223, 40);
        jt3.setLocation(223, 60);
        jt4.setLocation(223, 80);

        tbl1.setLocation(223, 200);


        lbl1.setSize(230, 20);
        lbl2.setSize(230, 20);
        lbl3.setSize(230, 20);
        lbl4.setSize(230, 20);
        lbl5.setSize(230, 20);
        lbl6.setSize(230, 20);

        lbl8.setSize(230, 20);
        lbl9.setSize(230, 20);

        btn1.setSize(150, 20);
        btn2.setSize(150, 20);

        jt1.setSize(230, 20);
        jt2.setSize(230, 20);
        jt3.setSize(230, 20);
        jt4.setSize(230, 20);
        jt5.setSize(230, 20);
        jt6.setSize(230, 20);
        jt7.setSize(230, 20);
        jt8.setSize(230, 20);
        jt9.setSize(230, 20);
        tbl1.setSize(1, 1);


        // pack the frame for better cross platform support
        f.pack();
        // Make it visible
        f.setVisible(true);
        f.setSize(600,500); // default size is 0,0
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    } // End of Gui Method

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
           public void run() {
                new Driver();

           }
        });
    } // End main Method

       } // End class Driver

数组 在地址类中

    public void ShippingLabel(String[]args) {
  Object [][] sl = {{"555 Hello Ln", "Capital, TX 77777"}};
    }

在主类中

  btn1.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                btn1MouseClicked(evt);
                tbl1.setText(ShippingLabel(sl[0]));

            }
        });

Answer 1

使用DefaultTableModel 在JTable 中添加新行

示例代码：

• 这里的表有 4 个现有行

• 单击按钮时会添加一个新行

  Object data[][] = { { "111Hello Ln", "Capital", "TX 77777" },
      { "222 Hello Ln", "Capital", "TX 77777" },
      { "333 Hello Ln", "Capital", "TX 77777" },
      { "444 Hello Ln", "Capital", "TX 77777" } };
  String col[] = { "Name", "Capital", "TX" };
  
  final DefaultTableModel model = new DefaultTableModel(data, col);
  final JTable table = new JTable(model);
  
   ....
  
  btn1.addMouseListener(new java.awt.event.MouseAdapter() {
      public void mouseClicked(java.awt.event.MouseEvent evt) {
          btn1MouseClicked(evt);
  
          Object [][] sl = {{"555 Hello Ln", "Capital", "TX 77777"}};
          model.addRow(ShippingLabel(sl[0]));
  
      }
  });
