    Try the jAWTRobot library as I think that has a get physical memory size method.

    You could find it yourself applying the proper method for the OS your program is running on.
    Windows: use "wmic" (eg. wmic MEMORYCHIP get BankLabel,DeviceLocator,Capacity,Tag)
    Linux: use "dmidecode" (eg. dmidecode -t 17 | grep "Size.*MB" | awk '{s+=$2} END {print s / 1024}')
    MacOS: use "SPHardwareDataType" (eg. /usr/sbin/system_profiler SPHardwareDataType | grep " Memory:")

    All methods above untested. I just searched the Internet.

    Please come back and let oss know how you used it. The greatest thing with a mind of your own is that someone else likes to do the thinking for you :)
