How can I show System Information On GUI using AWT/Swing

[Yatin Shah]

Hi,

I have code to get System Information. But, it shows whole information. I just want to display Information like version of OS and version of Java, RAM Registration of OS capacity of HDD and Which Processor is mountain etc. Is it possible to get perticular information?

Thanking You
Yatin.
