java設計模式（簡例）—-適配器模式

//建立DBConnection借口

package com.adepter.test;public interface DBConnection {public void insert();}

//建立DBConnection的實作類別DBConnectionImpl

package com.adepter.test;public class DBConnectionImpl implements DBConnection {@Overridepublic void insert() {// TODO Auto-generated method stubSystem.out.println("這是DBConnection類");}}

//建立Regist介面

package com.adepter.test;public interface Regist {public void writeFile();}

//建立Regist介面的實作類別

package com.adepter.test;public class RegistImpl implements Regist {    @Override    public void writeFile() {        // TODO Auto-generated method stub        System.out.println("這是Regist類");    }}

//建立Adpater適配器類，實現介面的回調

package com.adepter.test;public class Adapter implements Regist {public DBConnection dbcon;public Adapter(DBConnection dbcon){this.dbcon=dbcon;}@Overridepublic void writeFile() {// TODO Auto-generated method stubdbcon.insert();}}

//建立Test測試類別

package com.adepter.test;public class Test {        public static void main(String[] args) {        // TODO Auto-generated method stub        DBConnection dbcon=new DBConnectionImpl();        Regist reg=new Adapter(dbcon);        reg.writeFile();    }}
