How to increase the heap space size -is there any parameter to pass to JVM

Question

I created a memory buffering module which can be use to buffer log records and write to hard disk.disk writing is done by a separate thread so the main application won't be delayed. and memory for new errors are allocated dynamically. when i test this it gave this exception Exception in thread "Thread-62" java.lang.OutOfMemoryError: Java heap space then I test 100,000 of log records at a time and sleep the thread for 1 second to let the garbage collector do its job this works fine. but when i increase the log records count further it gave the above error. so i want to know whether is there a way to give the heap memory size to the VM as a parameter before running it.
