Shortcut Keys in Java

How could I (for example) maximize the window from tray icon when a specified key combination is pressed?

I think you should use some GUI event to detect the keyboard presses and the JNI (Java Native Interface) to maximize the window.

Look at this example about JNI and window maximization. You should look the guide of JNI too.
