本文实例为大家分享了java实现通讯录管理系统的具体代码，供大家参考，具体内容如下

完成项目的流程：

1.根据需求，确定大体方向 2.功能模块分析 3.界面实现 4.功能模块设计 5.coding 6.代码测试

下面是源代码：

import java.awt.Container; import java.awt.GridLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.util.ArrayList; import java.util.Scanner; import java.util.concurrent.SynchronousQueue; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.WindowConstants; import javax.swing.text.html.HTMLDocument.Iterator; class Infro{ public String id; public String name; public String sex; public String address; public String e_mail; public String phoneNumber; static int index = 0; static ArrayList list = new ArrayList(); static int len = list.size(); //构造函数 public Infro(String id,String name,String sex,String address,String e_mail,String phoneNumber){ this.id = id; this.name = name; this.sex = sex; this.address = address; this.e_mail = e_mail; this.phoneNumber = phoneNumber; } public String toString(){ return "编号："+id+" 姓名："+name+" 性别："+sex+" 通讯地址："+address+" 邮箱地址："+e_mail+" 电话："+phoneNumber; } /** * 添加功能 **/ public static void addFunction(){//添加功能 Infro infro = new Infro("","","","","",""); System.out.println("请输入添加的数据："); Scanner in = new Scanner(System.in); System.out.println("输入编号："); infro.id = in.next(); System.out.println("输入姓名："); infro.name = in.next(); System.out.println("输入性别："); infro.sex = in.next(); System.out.println("输入通讯地址："); infro.address = in.next(); System. out.println("输入邮箱地址："); infro.e_mail = in.next(); System.out.println("输入电话："); infro.phoneNumber = in.next(); list.add(index,infro); index++; if(list.isEmpty()){ System.out.println("数据添加失败啦"); }else{ System.out.println("数据添加成功啦"); len++;//list集合长度加一 // System.out.println(list.get(0).toString()); } } // public static void deleteFunction(){//删除功能 // System.out.println("输入要删除的联系人的编号"); // Scanner in_2 = new Scanner(System.in); // String d1 = in_2.nextLine(); // for(int a= 0; a
