i download a stratege and compile it,but get a message like this :

01:18:10 The public type MA6_Play must be defined in its own file
01:18:10 ^^^^^^^^
01:18:10 public class MA6_Play implements IStrategy {
01:18:10 1. ERROR in C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\jfxide\tmp\compile\201007MA6_Play.java (at line 7)
01:18:10 ----------

java class and file names should match.
