Java Heap Space
I use the BlueJ editor. I'm sorry if any of you are unfamilar with BlueJ, but please try to help
I'm not sure why I have this error but now it says this:
java.lang.OutOfMemoryError: Java heap space
I looked up what the error is on the internet. I saw how to increase the heap size my changing the bluej.defs file, so I did that. It still gives me the same error and I don't know how to fix it. One source said that when you run the file, you should specify this as arguments -Xms1024m -Xmx1024m, but I'm not sure exactly how to use it because all it says is variable is that variable Xms1024m can't be found.

The error message is indicating that the application is using more memory than is allocated for the JVM. Could be that the application is very big or that a memory leak could be happening. Since I am not familiar with BlueJ, and its overheads, my approach would be to compile and run in the standard way from a command line and then see if the error appears. If so, then increase the allocated memory incrementally from the defaults by using -Xms?m -Xmx?m as arguments to the run command.-Xm32?m -Xmx128m are the defaults, then try perhaps -Xms128m -Xmx256m for starters.
I use to get this same error using BlueJ. What I did (and it worked) is I used the command prompt to locate the folder containing the program. My main class was called Driver, this command made it work perfectly:java -Xmx1024m DriverGive it a shot.
