How we can get the processor name and registered to informations from PC? How is it possible through Java? I'm using windows OS.

Answer 1

How its possible through java?

Generally, this is not possible to do in Java. You would have to go through an external program (see ProcessBuilder) or through a native library (written in for instance C++).

You could do

System.getProperty("os.arch");

to get the OS architecture though. This gives "amd64" on my machine.

The page here lists a few other system properties too, but these seem to be VM specific though:

sun.cpu.endian=little
sun.cpu.isalist=pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86

Answer 2

There is a library called Sigar out there that can do all those fancy things.

The sigar jar can be called 'standalone' to explore the system:

$ java -jar sigar.jar
sigar> free
             total       used       free
Mem:       8388608    7940428     448180
-/+ buffers/cache:    5872060    2516548
Swap:       262144      95296     166848
RAM:        8192MB

For this to work, you also need the respective .dll or .so in the classpath

In RHQ-project we use Sigar for many of those statistics - you can browse the code here.
