通过单击鼠标获取JTable的特定单元格的值

Question

I have a JTable and Given such codes:

jTable.addMouseListener(new MouseAdapter(){
               public void mouseClicked(MouseEvent e){

                   System.out.println(jTable.getRowCount());
                   System.out.println(jTable.getModel().getValueAt(jTable.getRowCount(), 0));
               }
           });

If I click on a certain row, like in the picture above, I clicked the second row, how can I get that row's content?(How to get the Canada)?

Answer 1

Personally, I use the Mouse Clicked event. You could try something like this inside your event method:

private void myTableMouseClicked(java.awt.event.MouseEvent evt) {                                          
    int row = this.myTable.getSelectedRow();
    int column = this.myTable.getSelectedColumn();
    this.myTable.getValueAt(selectedRow, selectedColumn);
} 

Be aware that the getValueAt method returns an Object. You probably will need to cast the Object returned into the object it is supposed to be. And also you could have a global variable that's going to have the value returned by getValueAt for using it as you need.

I hope it helps.
