system programming with java

hi,

i was trying to fetch system related data, like processor usage, through java .. but i couldn't .. i couldn't find any API for the purpose..

finally used some shellscripting...

is there any API for these purpose?

If there are no such APIs then how java.io works?

how it interact with hardware? how it read input from IO devices?

think about it. Java is a platform independend language. What you are asking is HIGHLY platform specific. Why would Java support it? Your best bet for platform specific stuff in Java is in the java.net projects such as this one:https://jdic.dev.java.net/

Java technology includes an abstraction layer called the Java Virtual Machine. This JVM isolates all system dependencies. Once a JVM exists for a platform, pure Java programs (in bytecode form) will run on that platform.
