    }

    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getMobile()

    public void setMobile(String mobile)
    {
        this.mobile = mobile;
    }

}

这可能有助于删除重复项

if(!contacts.contains(con))
 {
    contacts.add(con);
 }
