Exception in thread "main"

[robert22]

I am getting the error: Exception in thread "main" java.lang.OutOf MemoryError: Java heap space.

Use the -xms and -xmx flags to allocate more memory.

[robert22]

okay i will try that.

[dev7060]

The default memory is usually 64m. So I believe -Xmx256m would work well. More options to control memory use can be viewed by the java -X command.

java.lang.OutOf MemoryError exception can also be thrown by native library code when a native allocation can't be satisfied. Following are the various cases when the OutOfMemory error might occur:

1) Due to Java Heap Space
2) When the GC Overhead limit exceeded
3) Permgen space is thrown
4) Metadata is allocated in native memory. if metaspace for class metadata is exhausted
5) Requested array size exceeds VM limit
