Java JTable Click Event In Netbeans

Java JTable Code -  Java JTable Click Event Using NetBeans .

                                                                           


In this java Tutorial we will see How To Use A JTable Mouse Clicked In Java Using NetBeans
To Display The Selected Row Columns Sum .


*Java Courses Java Complete Course
                            Java Swing Course





- in the mouse click we will get the row selected and get the sum  of the row columns and display it in JOptionPane :

    private void jTable_ClickMouseClicked(java.awt.event.MouseEvent evt) {                                          
       // get the selected row
       int index = jTable_Click.getSelectedRow();

       TableModel model = jTable_Click.getModel();

       int value1 = Integer.parseInt(model.getValueAt(index, 0).toString());
       int value2 = Integer.parseInt(model.getValueAt(index, 1).toString());
       int value3 = Integer.parseInt(model.getValueAt(index, 2).toString());
       int value4 = Integer.parseInt(model.getValueAt(index, 3).toString());
       
       int sum = value1+value2+value3+value4;
       
        JOptionPane.showMessageDialog(null, "Sum = "+sum);
    }
