My best guess to your problem is that you have not installed a JDK (Java
Development Kit), but is running on a plain JRE (Java Runtime Environment).

Take a look on the system requirements and tutorial for how to install and
configure Robocode here:

I have found the reason for this . I had already installed JDK before i
installed Robocode . The point is that i edited the name of the method
thinking it doesnt affect the program (because when i tested , i found the
robot still ran , but didnt recognize he doesn't shoot the target , how
careless i am :P) . Thank you anyway , thanks for posting the advise for me
:)
