Java Core, Level 4, Lesson 8
Resolved
CodeGym security exception. You are performing a forbidden or potentially dangerous operation.Hey girls and guys, I can't find the problem here. There are 10 exceptions in my list. According to the recommendation (in the title) I seem to invoke an unhealthy exception. Does anybody know which it could be? best regards Mathis

Games, Level 0, Lesson 2
Resolved
Fourth task is failing. Can somebody please explain why?Final task is failing with the following error: The onKeyPress(Key) method must call the gameOver() method and do nothing else, if the canUserMove() method returns false. Recommendation from your mentor: Be sure that the gameOver() method is called if the canUserMove() method returns false.

Java Core, Level 9, Lesson 5

What are they asking for? ACSII numbers do not match with their output example.I don't get what they are asking for here. It makes no sense. An ordinal number is a positional number. ACSII numbers are not really positional, but if that is what we are looking at none of the results they give make any sense.

Hey guys I almost got this one.It prints out the way the example is shown but then the program terminates. How do I get it to not terminate? I'm not sure if that's part of the task because it doesn't specify but everything seems fine when I run it.
