How to get OS level information using Java?

I am looking for a method or package in java where we can get OS level Information.

Is there any package equivalent to Management Object Searcher(c#) in java?

You can get OS and it version by using below code snippet:

      String OS = System.getProperty("os.name");             
      System.out.println("Your OS is : " + OS);

      String OSVersion = System.getProperty("sun.arch.data.model");             
      System.out.println("Your OS version is : " + OSVersion + " bit");

One simple line of code can do this.

System.getProperty("os.name");

and more specifically what OS level info you are looking ?

For memory related stuff you can have something like this.

System.out.println("Free memory (bytes): " + 
    Runtime.getRuntime().freeMemory());


long maxMemory = Runtime.getRuntime().maxMemory();

System.out.println("Total memory (bytes): " + 
    Runtime.getRuntime().totalMemory());

Thanks

Get OperatingSystemMXBean with 

java.lang.management.ManagementFactory
OperatingSystemMXBean os = ManagementFactory.getOperatingSystemMXBean();

If you know which OS native library you need to get the information you desire then call it using JNI.
