I'm not sure if you're going to get exactly what you want, but maybe in one of the classes MemoryMXBean or MemoryPoolMXBean .

Instances of these classes can be obtained with the help of class ManagementFactory . example:

MemoryMXBean memory = ManagementFactory.getMemoryMXBean();

If it is to 'monitor' the process, there are the jconsole or jvisualvm commands that come together with the JDK to monitor the virtual machines - they provide various graphics including memory usage. JDK also offers a variety of instruments .

Another possibility is to use the -verbose:gc (and -XX:+PrintGCDetails ) option on the command line. Additionally -Xloggc:filename to write to a file. I used GCViewer to analyze these logs, very interesting (a few years ago).
