我試圖根據用戶輸入的內容添加一個新行到我的JTable，並重復多次用戶註冊。例如，假設用戶在registerTF中輸入了「Susie」，對於lengthTF輸入了「11:00」，對於IDTF輸入了「60」。我可以在examInfo.java中以行的形式添加到我的JTable中，但沒有問題，但我該如何重複執行，因此下一次運行Registration.java時，在這些字段中輸入的所有內容都將放入一個全新的行中我的JTable。在任何人問起之前，不，這不是我爲家庭成員做的家庭作業。向JTable添加一個新行
這裏是我的Registration.java代碼：
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Registration extends JFrame{
private static final int WIDTH = 400;
private static final int HEIGHT = 300;
private JLabel registerL, lengthL, IDL;
private JTextField registerTF, lengthTF, IDTF;
private JButton registerB, exitB;
//Button handlers:
private CalculateButtonHandler cbHandler;
private ExitButtonHandler ebHandler;
public Registration(){
registerL = new JLabel("Enter Name: ", SwingConstants.RIGHT);
lengthL = new JLabel("Enter Registration: ", SwingConstants.RIGHT);
IDL = new JLabel("Length of exam: ", SwingConstants.RIGHT);
registerTF = new JTextField(10);
lengthTF = new JTextField(10);
IDTF = new JTextField(10);
//Specify handlers for each button and add (register) ActionListeners to each button.
registerB = new JButton("Register");
cbHandler = new CalculateButtonHandler();
registerB.addActionListener(cbHandler);
exitB = new JButton("Exit");
ebHandler = new ExitButtonHandler();
exitB.addActionListener(ebHandler);
setTitle("Registration");
Container pane = getContentPane();
pane.setLayout(new GridLayout(4, 2));
//Add things to the pane in the order you want them to appear (left to right, top to bottom
pane.add(registerL);
pane.add(registerTF);
pane.add(lengthL);
pane.add(lengthTF);
pane.add(IDL);
pane.add(IDTF);
pane.add(registerB);
pane.add(exitB);
setSize(WIDTH, HEIGHT);
setVisible(true);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
private class CalculateButtonHandler implements ActionListener{
public void actionPerformed(ActionEvent e){
}
}
public class ExitButtonHandler implements ActionListener{
public void actionPerformed(ActionEvent e){
System.exit(0);
}
}
public static void main(String[] args){
Registration rectObj = new Registration();
}
}
這是我examInfo.java代碼在我的JTable的是：
import java.util. Arrays;
import java.util.Vector;
import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class examInfo {
public static void main(String agrs[]){
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Vector<String> rowOne = new Vector<String>();
rowOne.addElement("Row1-Column1");
rowOne.addElement("Row1-Column2");
rowOne.addElement("Row1-Column3");
Vector<String> rowTwo = new Vector<String>();
rowTwo.addElement("Row2-Column1");
rowTwo.addElement("Row2-Column2");
rowTwo.addElement("Row2-Column3");
Vector<Vector> rowData = new Vector<Vector>();
rowData.addElement(rowOne);
rowData.addElement(rowTwo);
Vector<String> columnNames = new Vector<String>();
columnNames.addElement("Time");
columnNames.addElement("Length");
columnNames.addElement("ID");
JTable table = new JTable(rowData, columnNames);
table.setValueAt("11:00 Wed", 0, 0);
JScrollPane scrollPane = new JScrollPane(table);
frame.add(scrollPane, BorderLayout.CENTER);
frame.setSize(300, 150);
frame.setVisible(true);
}
}
