Question: I am writing a Java application for system with small memory.

To make it reliable I would like to monitor memory size in my program and try to decrease program activity to enable Garbage Collector do its job before all memory will be consumed. When enough memory will be available program must continue the job.

How can I info about free memory in my Java application?

Answer: Your idea to design long time running program for an extreme environment is excellent! Smile

Use Runtime.totalMemory() - you get the total amount of memory in the Java virtual machine. This value varies all the time, depending on the host environment. Note that the amount of memory required to hold an object of any given type may be implementation-dependent...

and

Runtime.freeMemory() - you get info about free memory in the Java Virtual Machine. Calling the gc method may result in increasing the value returned by freeMemory.
