How to get information about the system?

Question

Java

How can I get information about the system? For example, about the processor, video card, RAM, motherboard chipset, etc.

Answer 1

Very little information can be obtained through Runtime.getRuntime().methods() but it is highly discouraged to believe them!
There was also a wonderful project SIGAR but it seems to have died.
And the surest way is to write a native lib (dll\so\dylib) for the desired platform and then hook it through JNI.
