system calls in java

hi

how to access system calls in java eg: determining whether capslock state is ON or OFF.

For starters, System calls will most likely depend on what platform/OS you're running on.

I wish I knew more about this to be honest but I did a google search on the caps lock idea in java and got this piece of code:

java.awt.Toolkit.getDefaultToolkit().getLockingKeyState(java.awt.event.KeyEvent.VK_CAPS_LOCK);

There are more on which events you can get here:

KeyEvents (http://java.sun.com/j2se/1.5.0/docs/api/java/awt/event/KeyEvent.html)
and the ToolKit API:

ToolKit (http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Toolkit.html)

Anyways, depending on what you're searching for as far as other system commands go depends on how it can be used.
