Memory heap error

[Jesus Angeles]

Hi,

I am getting this below.

    Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
        at java.util.ArrayList.<init>(ArrayList.java:112)
        at java.util.ArrayList.<init>(ArrayList.java:119)

The program needs lots of memory.

Is it possible to increase the heap memory for my program?

This can have two reasons:

* Your Java application has a memory leak. There are tools like YourKit Java Profiler that help you to identify such leaks.
* Your Java application really needs a lot of memory (more than 128 MB by default!). In this case the Java heap size can be increased using the following runtime parameters:

java -Xms<initial heap size> -Xmx<maximum heap size>

Defaults are:

java -Xms32m -Xmx128m

Increase Java Heap Size

Thank you Ryan.
