如何从JTable 1到JTable 2获取值？

Question

I have no idea how to pass a value from jtable1 to jtable2 . For an example, When I double-click the row from jtable1 , and it will display the same value at jtable2 . Any idea? I think hard for a long time, and I can't solve the problem.

Answer 1

If you want to transfer value from one jTable to another jTable within the same JFrame, in the mouse click event of jTable1 give

    jTable2.setValueAt(jTable1.getValueAt(0, 0).toString(), 0, 0);

    jTable2.setValueAt(jTable1.getValueAt(0, 1).toString(), 0, 1);

    jTable2.setValueAt(jTable1.getValueAt(0, 2).toString(), 0, 2);

Hope this will resolve your problem...

Study the tutorial section How to Use Tables: User Selections and learn how to How to Write a List Selection Listener . In your jtable1 listener, you can update the TableModel of jtable2 to display any related data.
