Without seeing the code you've designed erroneously (which appears to be Class1.java, line 203), my best guess is that you've tried to create an array with a size larger than the RAM will allow you to.

If you're looking for a place to check in a stack, the first place to look (in my experience) is at the highest "at" line that is your own file--in this case, Class1.java:203.

Hi.. but I also got different error message below:

That could've been caused by the same StringBuilder eating up (nearly) all the memory; when something else needs a bit of memory and it isn't available the same OutOfMemory error is thrown.

kind regards,

Jos
