When you ran the
java program, did you pass it any parameters? In this example, the args[] variable represents parameters passed on the command line.
While it is possible to add the parameters to TextPad and SunONE, I would suggest just using a Command Prompt; it makes it easier to change the parameters.
Try:
"java MonthName 1"
as your command line and see if youstill get the error.
