I would say there is actually very little difference. Maybe 1 would be
slightly faster due the missing assignment. The
most efficient would probably be:
public MyClass implements ClickHandler {
public void onClick(com.google.gwt.event.dom.client.ClickEvent
event) {
Window.alert("msg");
}
//Code 3
button.addClickHandler(this);
}
