從指定表格中提取值

我想單擊按鈕save來提取值。從JTextField和JTable行和列中提取值。只需要一個大概的想法如何提取並保存不同變量的值。我想在按鈕保存下執行這些保存操作。從指定表格中提取值

除了調用textField.getText()，你可以獲得一個參考你的表的模型，並使用getValueAt()在值迭代：

JButton save = new JButton("Save"); 
save.addActionListener(new ActionListener() { 
    @Override 
    public void actionPerformed(ActionEvent e) { 
     System.out.println(textField.getText()); 
     TableModel model = table.getModel(); 
     for (int r = 0; r < model.getRowCount(); r++) { 
      for (int c = 0; c < model.getColumnCount(); c++) { 
       System.out.print(model.getValueAt(r, c) + " "); 
      } 
      System.out.println(); 
     } 
    } 
});

從JTextField中可以調用getText方法來獲取文本框的內容的形式String，如：

String myString = textField.getText();

和來自JTable的單元格？ – Asdakamessoy

我不知道JTable。，對不起 – Abubakkar

從JTable使用getValueAt方法來檢索值。

從JTextField使用textField.getText()通過@Abu
