What would be getDesktopProperty() for Linux?

I have to read the high contrast mode of the native os and have to apply the settings on my product. Now for windows I have done some thing like this:

 try {
       Toolkit toolkit = Toolkit.getDefaultToolkit();
       boolean highContrast = (Boolean)toolkit.getDesktopProperty("win.highContrast.on" );
 }catch(Exception e) {
 }

This works fine for Windows but I need the desktop property to read linux high contrast settings. Can anyone please tell me what would be the desktop property for linux?
