大二用java开发的一个不用数据库支持的通讯录

在大二第一学期的时候，在学习了JAVA中的输入输出流后老师要我们做一个通讯录。其功能可以添加删除和在关闭时保存信息，保存和导入数据用的技术是纯粹的IO流，没有设计到数据库，呵呵，功能是实现出来了，但效率可能不怎么好，希望高手们看完后给小弟点意见，我会改进的，OK，以下是我的原代码和试用方法说明：

代码：

   static int munber=0;    //这个就是整个程序的计数器

}

{
   int jj=j;
   Integer id=new Integer(2);
   id=jj;
   String iD=id.toString();

   return iD;

}
static public String id2()//添加自加功能的方法,显示在文本框上
{
   int j1=j+1;
   Integer id2=new Integer(1);
   id2=j1;
   String jd=id2.toString();
   return jd;
 
 
 
}

    public String getValue()
    {
    String value="ID号:"+ this.ID+"    "+"姓名:"+this.Name+"    "+"地址:"+this.Address+"    "+"电话:"+this.Phone+"    "+"单位:"+this.Work+'\n';
    return value;
   
   
    }
