It is possible to increase heap size allocated by the Java Virtual Machine (JVM) by using command line options.

-Xms        set initial Java heap size
-Xmx        set maximum Java heap size
-Xss        set java thread stack size

If you are using the tomcat server, you can change the heap size by going to Eclipse/Run/Run Configuration and select Apache Tomcat/your_server_name/Arguments and under VM arguments section use the following:

-XX:MaxPermSize=256m
-Xms256m -Xmx512M

If you are not using any server, you can type the following on the command line before you run your code:

java -Xms64m -Xmx256m HelloWorld
