对设计模式—Singleton模式的认识
在过去取老婆可以三妻六妾，不过现在有了法律规定一人只能一妻。

public class Wife{    private static  Wife wife = new Wife();    public static Wife getWife()    {       return wife;    }    private Wife()    {         }}

public class Wife{    private static  Wife wife ;    public static synchronized Wife getWife()     {　　     if (wife == null)　　　  　 wife ＝ new Wife();　　       return wife; 　　     }     private Wife()    {      }
