If you are using JDK 1.5 you can use the new static import mechanism to achieve this.
import static java.lang.Math.*;
You cannot do this is pre-1.5 releases.
It depends on the context of the consume() method. But if you imagine an event being fired to a linked list of objects then if an object in the list "consumes" the event then the event will not make it to the linked objects further down the list.
e.g. If it was a mouseevent and the first object in the list is a button then the button object will "consume" the event and the panel/frame/window/etc objects "below" the button will not be aware that a mouseevent occurred.
