Exception in thread “main” java.lang.OutOfMemoryError: Java heap space
Java, Programming January 15th, 2007When this exception occurs, it means java runs out of memory.
You can increase memory(heap size) by run java including these parameters:
-Xms[initial heap size] -Xmx[maximum heap size]
For example, set initial heap size to 128m and maximum to 256m.
java -Xms128m -Xmx256m
In NetBeans, simply goes to Project Properties –> Run.
Then you can add these parameters in VM Options.

I’m not sure on JCreator but there must be a setting similar to NetBeans that let you add argument when execute java.exe commmand.
