I know this question is a frequently one, however I checked some solutions from this site, but it seems like it didn’t work for me.

So, I have written a small java program, and I want to know how much memory it consumes at different execution moments. I tried Runtime.getRuntime.total() and Runtime.getRuntime.free(), but I’m getting the (almost) same results each time.

I am not interested in how much memory is there available or used by the entire JVM, I want to know specifically for my java process.

    this will get you how much heap memory your process has used.

    MemoryUsage heapMemoryUsage = ManagementFactory.getMemoryMXBean().getHeapMemoryUsage();
heapMemoryUsage.getUsed();

    you can also get all your memory pools and iterate through them to determine other memory usage

    List<MemoryPoolMXBean> memoryPoolMXBeans = ManagementFactory.getMemoryPoolMXBeans()

    you could also use jvisualvm to interrogate your application.
