I. Introduction to Adapter Mode

The simplest way for a class in Java to use another object that is irrelevant to itself is to use the adapter pattern.

The following is a simple code implementation:

 Package Com.lz.adapter; /*  */Publicclass  adaptee    {publicvoid request () {        System.out.println ("provides related services. ");    }}

 PackageCom.lz.adapter;/** Adapters with adapter interface are implemented*/ Public classAdapterImplementstarget{/** methods that are called by the member variable to be adapted to the object*/    Privateadaptee adaptee;  PublicAdapter (adaptee adaptee) {Super();  This. Adaptee =adaptee; } @Override Public voidHandlereq () {adaptee.request (); }}

 Package Com.lz.adapter; /*  */Publicinterface  Target    {void  handlereq ();}

here is like the computer wants to use the mouse to need the USB or the PS/2 interface to link the two, here the adapter will play a the role of the connection.
