monitoring - How to dynamically monitor Java heap size?

Question

I am trying to monitor the java heap size dynamically. Does anybody know how to get the maximium memory used in the process of running a piece of codes? Does the Runtime.maxMemory() do the trick? Thanks

Answer 1

maxMemory() returns the maximum amount of memory that java will use. So That will not get you what you want. totalMemory() is what you are looking for though. See The docs
