这是一个Java程序，它定义了一个Person类，包含id、name、phoneNumber和address属性，并实现了相关方法。Utils类用于生成通讯录，main方法则通过Map存储Person对象并按name值分类。用户输入姓名和电话号码，程序会查找匹配的联系人并输出。如果找不到，输出"Not Find!"。最后输出Map的大小。

6-4 jmu-Java-m06 根据姓名以及电话号码查找联系人 (20分)
该程序包含：

Person类：

属性：int id, String name, String phoneNumber，String address。

方法：

无参构造方法，有参构造方法（id, name, phoneNumber，addres）,

各个参数的getter/setter方法，

toString()方法。

Utils类：

用于生成通讯录(具体实现下面已给出)

main方法：

使用Utils类创建出一个通讯录personList，使用Map对personList中的person对象进行分类存储，其中key为person的name值，value为对应的person对象的List列表（即将相同name值的person对象放在一起）

输入一个number

接下去输入number行的name以及phoneNumber值，以空格分开

查找map，如果找到结果则输出对应的person对象，找不到则输出提示信息

最后一行输出map的数量，即map.size()(该行输出在输出样例中未显示)

Utils类实现如下：

class Utils{

private static final Random rd = new Random(3);
private static final int number = 200000;
private static List<String> getPersonName(){
	StringBuilder sb = new StringBuilder();
	List<String> names = new ArrayList<String>();
	for(int i=0;i<Utils.number;i++) {
		sb.delete(0, sb.length());
		for(int j=0;j<4;j++) {
			if(j==0) {
				sb.append((char)('A'+rd.nextInt(26)));
			}
			else {
				sb.append((char)('a'+rd.nextInt(26)));
			}
		}
		names.add(sb.toString());
	}
	return names;

}
private static List<String> getPhoneNumber(){

	String[] telFirst="134,135,136,137,138,139,150,151,152,157,158,159,130,131,132,155,156,133,153".split(",");
	StringBuilder sb = new StringBuilder();
	List<String> phoneNumbers = new ArrayList<String>();
	for(int i=0;i<Utils.number;i++) {
		sb.delete(0, sb.length());
		for(int j=0;j<9;j++) {
			if(j==0) {
				sb.append(telFirst[rd.nextInt(telFirst.length)]);
			}
			else {
				sb.append(rd.nextInt(10));
			}
		}
		phoneNumbers.add(sb.toString());
	}
	return phoneNumbers;
}

private static List<String> getPersonAddress(){
	List<String> addresses = new ArrayList<String>();
	String[] roads = {"HuanDao Road","WenZeng Road","ZhongShang Road","KaiHe Road","NanHua Road","SongBai Road","BinShui Road","ShiGu Road","JiYuan Road","YinJiang Road"};
	StringBuilder sb = new StringBuilder();
	for(int i=0;i<Utils.number;i++) {
		sb.delete(0, sb.length());
		for(int j=0;j<2;j++) {
			if(j==1) {
				sb.append(roads[rd.nextInt(roads.length)]);
			}
			else {
				sb.append("Room "+rd.nextInt(100)+"-"+rd.nextInt(1000)+"-"+rd.nextInt(10000)+", ");
			}
		}
		addresses.add(sb.toString());
	}
	return addresses;
}

public static List<Person> getPersonList(){
	List<String> names = Utils.getPersonName();
	List<String> phones = Utils.getPhoneNumber();
	List<String> addresses = Utils.getPersonAddress();
	List<Person> persons = new ArrayList<Person>();

	for(int i=0;i<Utils.number;i++) {
		Person person = new Person();
		person.setId(i);
		person.setName(names.get(i));
		person.setPhoneNumber(phones.get(i));
		person.setAddress(addresses.get(i));
		persons.add(person);
	}
	return persons;
}

}

输入格式:
一个正整数number

接下去的number行：

输入name以及phoneNumber

输出格式:
如果找到对象则输出该对象

未找到对象则输出"Not Find!"。

输入样例:
5
Vern 15678785276
Paul 13369862612
Todd 15094198414
Mike 15079239680
Tony 13739215033

输出样例:
Not Find!
Person [id=162538, name=Paul, phoneNumber=13369862612, address=Room 8-446-6866, ShiGu Road]
Person [id=139814, name=Todd, phoneNumber=15094198414, address=Room 8-856-5546, JiYuan Road]
Not Find!
Person [id=184950, name=Tony, phoneNumber=13739215033, address=Room 71-896-9345, SongBai Road]
