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 .
- 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);
}
