帮我看下我的代码哪里出了问题？

}

}

    public void foreachset(people p1)

    {

    for(member cc:p1.members)

    {

    System.out.println(cc.phone+","+cc.pass);

    }

    }

    

    

}

/**  1.     System.out.println("账号或密码错误！请重新输入");这一句代码总是重复执行。

   2.   进入注册，注册成功后该怎样重新返回到登录时账号密码的输入界面？难道要把那段登录的代码复制到注册成功后面而不能用循环或者什么重新返回到那个位置上吗？

Answer 1

前言：贴代码要贴得规范，贴重点，贴得乱七八糟有耐心的人才给你看1，你把它写到了循环内导致重复执行2、while(true)
