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()
    {
  
    }
