Java APIs

I have a GUI program which appears to work for all test cases. Basically what it does is prints out data from a linked list allowing the user to traverse the list with Next and Previous buttons which call a list iterator next/previous method call, and then display the current item in the list. The original problem arose when dealing with alternating calls to next and previous, which since list iterator does not have a current pointer, returned the same element ad infinitum. I modified the method to check for alternating button presses, and it seems to work, except for cases where there are two elements in the list. In this case it still works, printing the correct element, but it also prints to the command line an Exception in Thread AWT...NoSuchElementException. My question is, is there any way to tell the program to not print out this stack trace and just keep running quietly through the Exception?
