Following are few options available to change Heap Size.

1 -Xms<size>        set initial Java heap size
2 -Xmx<size>        set maximum Java heap size
3 -Xss<size>        set java thread stack size

For example, you can set minimum heap to 64 MB and maximum heap 256 MB for a Java program HelloWorld.

java -Xms64m -Xmx256m HelloWorld
