獲取JTable中的選定行

Question

我有一個JTable，如下圖所示。當單擊行時，我希望它顯示所有選定的行值。

viewMovie

public class viewMovie extends javax.swing.JFrame { 

     public viewMovie() throws Exception { 
      initComponents(); 
      populateJTable(); 
     } 

     // create a methode to populate data Into JTable from Mysql database And Displaying Picture 

     public void populateJTable() throws Exception{ 
      MyQuery mq = new MyQuery(); 
      ArrayList<Movie> list = mq.BindTable(); 
      String[] columnName = {"Title","Date","Time","Price","Hall","Description","Image"}; 
      Object[][] rows = new Object[list.size()][8]; 
      for(int i = 0; i < list.size(); i++){ 
       //rows[i][0] = list.get(i).getID(); 
       rows[i][0] = list.get(i).getTitle(); 
       rows[i][1] = list.get(i).getDate(); 
       rows[i][2] = list.get(i).getTime(); 
       rows[i][3] = list.get(i).getPrice(); 
       rows[i][4] = list.get(i).getHall(); 
       rows[i][5] = list.get(i).getDescription(); 

       if(list.get(i).getImage() != null){ 

       ImageIcon image = new ImageIcon(new ImageIcon(list.get(i).getImage()).getImage() 
       .getScaledInstance(150, 120, Image.SCALE_SMOOTH)); 

       rows[i][6] = image; 
       } 
       else{ 
        rows[i][6] = null; 
       }  
      } 

      TheModel model = new TheModel(rows, columnName); 
      jTable1.setModel(model); 
      jTable1.setRowHeight(120); 
      jTable1.getColumnModel().getColumn(5).setPreferredWidth(150); 
     }

      jTable1.setModel(new javax.swing.table.DefaultTableModel(

       new String [] {

當我點擊一個細胞，它假設顯示所有行的值，但只顯示單元格的值。

Answer 1

一種選擇是打印所選行的數據向量：

DefaultTableModel model = (DefaultTableModel)jTable1.getModel(); 
System.out.println(model.getDataVector().get(selectedRowIndex)); 

或者你可以陸續打印單排的單元格的值：

TableModel model = jTable1.getModel(); 
for(int i = 0; i < model.getColumnCount(); i++){ 
    if(i > 0){ 
     System.out.println(", "); 
    } 
    System.out.println(model.getValueAt(selectedRowIndex, selectedColumnIndex)); 
} 
System.out.println(); 

Answer 2

不是一個答案（jhead的給你示例代碼），只是一個很長的評論。

當點擊一行，

一個適當的圖形用戶界面的設計應工作無論用戶使用鼠標或鍵盤來選擇一行。所以你應該使用ListSelectionListener。有關更多信息和示例，請參閱How to Write a ListSelectionListener的Swing教程部分。本教程使用JList，但對於JTable也是如此。

另外，如果選擇了多個行呢？

我希望它顯示所有選定的行值。

這是什麼意思？所有數據已經​​顯示在表格中。
