java通讯录代码分析

编写一个JAVA程序实现个人通讯录管理

这个太简单了,你问的是程序编制要点,那么我就告诉你:

①分析程序

关于你说的用java编写个人通讯录管理程序,这个程序代码

这本书有原代码,你自己可以看下

java 电子通讯录的载入和保存代码

思路如下：

确定电子通讯录的文字格式,比如纯文本文件,每条通讯记录一行,每项内容之间使用tab键间隔

使用最基础的IO读写,操作此文件.

载入时从文件一行行读入,使用split拆分各项内容,存入一个对应的通讯录对象中,所有的通讯录对象保存在一个List中；

保存时,以覆盖的方式写入文件,以相同的格式写入即可.

java通讯录全部代码！

import java.io.BufferedOutputStream;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.FileReader;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.Scanner;

public class AddList {

private String filePath = "";

private String bakPath = "";

private String content = "";

Scanner sc = new Scanner(System.in);

public String readFile(){

content = "";

if (isNull(filePath)) {

System.out.println("文件存储路径：");

filePath = sc.nextLine();

}

File file = new File(filePath);

FileReader fr = null;

try {

if (file.exists()) {

fr = new FileReader(file);

int n = 0;

while((n = fr.read(chars)) != -1){

String string = new String(chars, 0, n);

content = content ◆ string;

} else {

System.out.println("文件不存在");

} catch (Exception e) {

e.printStackTrace();

} finally {

if (fr != null) {

fr.close();

} catch (IOException e) {

return content;

public void writeFile(String path){

File file = new File(path);

FileOutputStream fos = null;

mkDirs(path);

fos = new FileOutputStream(file);

BufferedOutputStream bos = new BufferedOutputStream(fos);

PrintWriter pw = new PrintWriter(bos, true);

pw.print(content);

pw.flush();

} catch (FileNotFoundException e) {

if (fos != null) {

fos.close();

public void writeFile(){

mkDirs(filePath);

public void mkDirs(String filepath){

if (filepath.indexOf("\\") != -1) {

filepath = filepath.replaceAll("\\", "/");

int n = filepath.indexOf("//");

String path = filepath.substring(0, n) ◆ "//";

filepath = filepath.substring(filepath.indexOf("//") ◆ 1, filepath.length());

String[] files = filepath.split("/");

for (int i = 0; i files.length - 1; i◆◆) {

path = path ◆ files[i];

if (!file.exists()) {

file.mkdir();

public void addImfor(){

System.out.println("--------增加记录---------");

String name = "";

String tel = "";

String email = "";

content = readFile();

while(true){

System.out.println("姓名：");

name = sc.next();

System.out.println("电话：");

tel = sc.next();

System.out.println("Email：");

email = sc.next();

content = content ◆ name ◆ "" ◆ tel ◆ "" ◆ email ◆"==";

System.out.println("0、Exit 1、继续");

int i = sc.nextInt();

if (i == 0) {

break;

writeFile();

public void deleteImfor(){

System.out.println("---------删除记录---------");

String[] imfors = null;

System.out.println("你要删除的姓名是：");

if (content.indexOf(name) != -1) {

imfors = content.split("==");

for (int i = 0; i imfors.length; i◆◆) {

if (imfors[i].indexOf(name) != -1) {

imfors[i] = "";

实现一个通讯录程序,命令模式下的JAVA程序, 该程序具备添加,删除,合查看通讯录信息的功能~

你就怎么那么小气呢！给个几十分也不亏你！

算了,刚写的就便宜你了！

public class Shopping {

System.out.println("\t\t\t\t1.添加联系人信息\n");

System.out.println("请选择,输入数字或按"n"返回上一级菜单：");

num = scanner.nextLine();

if (num.equals("n"))

isR = true;

else if(num.equals("1")){

System.out.println("添加联系人信息");

System.out.println("输入联系人的姓名: ");

String birthDayNum = num;

System.out.println("输入联系人的电话: ");

System.out.print("是否继续添加（y/e）：");

String numJixu = scanner.nextLine();

if (numJixu.equals("y"))

else {

isEnd = true;

System.out.println("查看联系人");

System.out.print("请输入联系人姓名：");

String snum = scanner.nextLine();

int numberNum = Integer.parseInt(snum);

就给你发这么多吧！还有一点点自己琢磨吧！我也没时间整理了！！

Java问题,求解答,我太菜了,不会做

题目完整代码如下：

People类：

public?class?People?{

//?姓名

private?String?name;

//?电话号码

private?String?phoneNumber;

//?地址

private?String?address;

//?邮箱

private?String?mailBox;

public?People(String?name,?String?phoneNumber,?String?address,?String?mailBox)?{

super();

this.name?=?name;

this.phoneNumber?=?phoneNumber;

this.address?=?address;

this.mailBox?=?mailBox;

public?String?getName()?{

return?name;

public?void?setName(String?name)?{

public?String?getPhoneNumber()?{

return?phoneNumber;

public?void?setPhoneNumber(String?phoneNumber)?{

public?String?getAddress()?{

return?address;

public?void?setAddress(String?address)?{

public?String?getMailBox()?{

return?mailBox;

public?void?setMailBox(String?mailBox)?{

public?String?toString()?{

return?"People?[name="?◆?name?◆?",?phoneNumber="?◆?phoneNumber?◆?",?address="?◆?address?◆?",?mailBox="?◆?mailBox

◆?"]";

通讯录类：

/**

*?通讯录

*?

*

*/

public?class?AddressBooks?{

//?People类型数组,长度为10(可以自己定义长度)

//?添加联系人

public?void?addPeople()?{

//?查找联系人

public?void?findPeople()?{

Scanner?scanner?=?new?Scanner(System.in);

System.out.println("请输入要查找的联系人");

String?name?=?scanner.nextLine();

for?(int?i?=?0;?i?peoples.length;?i◆◆)?{

if?(name.equals(peoples[i].getName()))?{

System.out.println(peoples[i].toString());

return;

}?else?{

continue;

System.out.println("不好意思,没有该联系人");

public?static?void?main(String[]?args)?{

AddressBooks?addressBooks?=?new?AddressBooks();

addressBooks.addPeople();

addressBooks.findPeople();
