电话簿管理程序java

以下是一个简单的电话簿管理程序Java的示例，包括添加联系人、查找联系人、按电话号码查找联系人、按姓名排序联系人等功能：

import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;

public class PhoneBook {
    private ArrayList<Person> list = new ArrayList<Person>();

    // 添加联系人
    public void addPerson() {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入姓名：");        String name = input.nextLine();
        System.out.print("请输入电话号码：");        String telNum = input.nextLine();
        System.out.print("请输入地址：");
        String address = input.nextLine();
        Person person = new Person(name, telNum, address);
        list.add(person);
        System.out.println("添加成功！");
    }

    // 查找联系人
    public void searchPerson() {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入要查找的姓名：");
        String name = input.nextLine();
        boolean b = true; // 默认找不到
        for (Person person : list) {
            if (name.equals(person.getName())) { // 能进行到这里说明找到
                System.out.println(person.toString());
                b = false;
            }
        }
        if (b) {
            System.out.println("找不到对应信息！");
        }
    }

    // 按电话号码查找联系人
    public void searchByTelNum() {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入要查找的电话号码：");
        String searchTelNum = input.nextLine();
        boolean b = true; // 默认找不到
        for (Person person : list) {
            if (searchTelNum.equals(person.getTelNum())) { // 能进行到这里说明找到
                System.out.println(person.toString());
                b = false;
            }
        }
        if (b) {
            System.out.println("找不到对应信息！");
        }
    }

    // 按姓名排序联系人
    public void orderName() {
        Collections.sort(this.list, new OrderByName());
        for (int i = 0; i < list.size(); i++) {
            this.list.get(i).setId(i + 1);
        }
        System.out.println("排序成功");
    }

    // 主菜单
    public void mainMenu() {
        Scanner input = new Scanner(System.in);
        while (true) {

            System.out.println("1.添加联系人");
            System.out.println("2.查找联系人");
            System.out.println("3.按电话号码查找联系人");
            System.out.println("4.按姓名排序联系人");
            System.out.println("5.退出程序");
            System.out.print("请选择：");
            int choice = input.nextInt();
            switch (choice) {
                case 1:
                    addPerson();
