abstract:


Code:
if (e.getSource() == btnPay){
int sum  = 0;
for (int i=0; i < pickedCars.length; i++){
     sum = (int)(sum+pickedCars.getValue());                      txfTotalPrice.setText(" " + sum);
     }
   

   I am trying to write a simple shopping cart but I need some help in coding the payment button, which should display the SUM value of the items listed in array.The program is compiling but I am getting some errors msgs at the console like these:  at java.awt.EventDispatchThread.pumpEventsForHierarch y(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)
