让我分两部分来解决我的问题。
JTextfiled的JTable中获取价值？姓名和年龄应该从JTextfield jbutton1行动中回溯，点击jbutton2 Jtable的所有数据都应存储在SQL DB中。
以下是我的代码：
package tablefilterdemo;
public class Tableinputhroughtextbox extends javax.swing.JFrame {
public Tableinputhroughtextbox() {
initComponents();

jScrollPane1.setViewportView(jTable1);

1）如何从JTable中的文本字段中检索值？
我猜你的意思是JTextField？请注意拼写，因为编程是一项精确的练习，所以你不能在编码或问题上马虎。
您可以通过getText()方法获得教程告诉您的文本。请看看here。
2）所有数据如何在数据库中一次性存储？
请澄清你的问题。如果您正在寻找如何使用Java数据库，请查看here。有关如何使用JTable和表模型，请查看here。我建议您将数据库代码与Swing代码分开，以帮助简化调试和编码。
编辑1 关于将JTable与数据库一起使用，在这个问题上已经发布了大量的答案，你可以在这个网站上搜索这些答案。这不是一件小事，需要你做一些研究。例如，请查看以下链接：
编辑2 你在评论中提问：
好吧让我们坚持一个问题。在上面的代码中我创建了2个JTexfield和Button.Now在这里我想要那些检索到的数据如何在Jtable中显示？
如果您希望将两个JTextField中的数据放在JTable的一行中，请考虑执行以下操作：
Vector<String>或String数组，将两个字符串放入Vector或数组中，然后在DefaultTableModel变量上调用addRow(rowData)。这假定向量或数组名为rowData。addRow(...)方法，并且您可能会传入一个包含两个数据的自定义类的对象。如果你走这条路线，确保你的addRow(...)方法调用正确的fireTableXXX(...)方法，这里它将是fireTableRowsInserted(int firstRow, int lastRow)。但最重要的是，请务必阅读我上面链接的JTable教程，否则我的答案对你没有意义。
编辑3 例如，使用DefaultTableModel：
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.KeyEvent;
import java.util.Vector;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
@SuppressWarnings("serial")
public class MyTableEg extends JPanel {
private static final String[] COLUMNS = {"Column A", "Column B"};
private DefaultTableModel model = new DefaultTableModel(COLUMNS, 0);
private JTable table = new JTable(model);
private JTextField fieldA = new JTextField(10);
private JTextField fieldB = new JTextField(10);
private JButton button = new JButton(new ButtonAction("Add Data", KeyEvent.VK_A));
public MyTableEg() {
JPanel topPanel = new JPanel();
topPanel.add(fieldA);
topPanel.add(fieldB);
topPanel.add(button);
setLayout(new BorderLayout());
add(topPanel, BorderLayout.NORTH);
add(new JScrollPane(table), BorderLayout.CENTER);
}
private class ButtonAction extends AbstractAction {
public ButtonAction(String name, int mnemonic) {
super(name);
putValue(MNEMONIC_KEY, mnemonic);
}
@Override
public void actionPerformed(ActionEvent evt) {
// ***** here's the important bit of code
Vector<String> rowData = new Vector<String>(); // create a row Vector
rowData.add(fieldA.getText()); // fill it with data from JTextFields
rowData.add(fieldB.getText());
model.addRow(rowData); // and add to table model
}
}
private static void createAndShowGui() {
JFrame frame = new JFrame("MyTableEg");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(new MyTableEg());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
//I guess you already got value into your JTextField
//Here I'm getting only two column into my JTable, you can take as many as you need
jbutton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
//TODO Auto-generated method stub
DefaultTableModel model=(DefaultTableModel) table.getModel();
try
{
String s1,s2;
s1=tfield1.getText();
s2=tfield2.getText();
model.addRow(new Object[] {s1,s2});
}
catch(Exception ae){
ae.printStackTrace();
}
}
});
它可能有帮助:)
