There's no pure-Java way to get the total RAM installed in the system. You need to use platform-specific code, perhaps utilising JNI. If you Google for it, you'll probably find ready-made third-party libraries for this.

long memorySize = ((com.sun.management.OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean()).getTotalPhysicalMemorySize();
System.out.println(Math.round(memorySize / (1024 * 1024)));
