Java中在程序中设置代理服务器】find out the best way to design your listeners march 22, 2002 in "it might be efficient, but it aint oo," i presented an alternative way to implement the java.awt.actionlistener interface. in my opinion, creating one large actionperformed() method and simply switching between the various action commands does not represent the best approach. i said such an approach doesnt follow good object-oriented (oo) design. such statements always cause controversy, and, needless to say, my comments did! in fact, my answer generated quite a bit of reader feedback. in this java q&a, i present concrete examples i hope will justify my position and help you implement this practice in your programs. as an added bonus, my approach applies to any interface implementation you might write. lets start with a simple gui (graphical user interface). figure 1s gui comprises a panel containing three buttons and a label. when you press a button, the gui writes a message to the label indicating which button you pressed. to display the panel, i embedded it within a frame. however, for the purposes of todays java q&a, ill simply focus on the panel code. (please see resources for the full source code.) implementation following the discussion in the original java q&a, you can implement the buttons listeners in two ways. first, the panel can implement the actionlistener interface directly, or, second, you can create three listener classes whose instances listen to the buttons directly. lets look at the first choice in which the panel implements one large listener. wire the buttons directly to the panel the following class shows how to wire the buttons directly to the panel: import java.awt.borderlayout;import java.awt...
