You can get some limited memory information from the Runtime class. It really isn’t exactly what you are looking for, but I thought I would provide it for the sake of completeness. Here is a small example. Edit: You can also get disk usage information from the java.io.File class. The disk space usage stuff requires Java 1.6 or higher.

public class Main { public static void main(String[] args) { /* Total number of processors or cores available to the JVM */ System.out.println("Available processors (cores): " + Runtime.getRuntime().availableProcessors()); /* Total amount of free memory available to the JVM */ System.out.println("Free memory (bytes): " + Runtime.getRuntime().freeMemory()); /* This will return Long.MAX_VALUE if there is no preset limit */ long maxMemory = Runtime.getRuntime().maxMemory(); /* Maximum amount of memory the JVM will attempt to use */ System.out.println("Maximum memory (bytes): " + (maxMemory == Long.MAX_VALUE ? "no limit" : maxMemory)); /* Total memory currently available to the JVM */ System.out.println("Total memory available to JVM (bytes): " + Runtime.getRuntime().totalMemory()); /* Get a list of all filesystem roots on this system */ File[] roots = File.listRoots(); /* For each filesystem root, print some info */ for (File root : roots) { System.out.println("File system root: " + root.getAbsolutePath()); System.out.println("Total space (bytes): " + root.getTotalSpace()); System.out.println("Free space (bytes): " + root.getFreeSpace()); System.out.println("Usable space (bytes): " + root.getUsableSpace()); } } }
