Thank you both very much I made the changes both of you suggested and it worked. Thank You!!!

Ok, thanks, i'll try do something.

As for the problem, you have a private inner class called 'wait' (why doesn't it start with a capital? I'm it was mentioned to you in a previous discussion that Java classes should start with a capital) only has a constructor that takes no parameters (line 722): <Code Omitted> You are then trying to create a new instance of this inner class, eg on line 573: <Code Omitted> ... but you are passing a parameter ('null'). Same again on line 612 (the line numbers you gave in your post above seem to be wrong) a

You can be quite sure (provided you did not make any changes to it) that the Counter class code is okay -- that the problem you are experiencing is not due to its code. Usually, when people have a problem similar to what this appears to be, the problem is in their World subclass. Post its code.

Never mind, I figured it out. :)

Show the code of the Counter class and the code in your world class where you create and add it into the world.

figured that out too. anyway thanks for the help

Super_Hippo, thank you, everything works

"noticed" -- how? "doesn't contain any value" -- do you mean 'null'? "failure" -- was an exception thrown -- and if so, what did it say? Is this something that is found out before or after the 'shuffle' method is executed? If you are getting a NullPointerException error, posting its output and indicating which line the error occu

Thank you very much!

Ah, OK, I canSee. Many thanks!!!

First, create a simple functional counter. Then, work on its image. If you have a specific issue in either step, post the code you tried and explain the issue. After those steps, you can work on having a specific actor use an instance of the class.

Thank you davmac, thats so logic.. I'm a amateur, thats why i have noobie codes xDD

danpost, thank you! Got it working.
