根据@把邮箱的用户名和地址分离，以键值对应的方式放入HashMap中

import java.util.LinkedHashMap;import java.util.Scanner;public class Email {public static void main(String[] args) {LinkedHashMap<String, String> lhm = new LinkedHashMap<String, String>();Scanner sc=new Scanner(System.in);System.out.println("请输入邮箱：");while(true){String yx = sc.next();if(yx.equals("exit")){break;}String[] s = yx.split("@");  lhm.put(s[0], s[1]);}System.out.println("请输入你要查找的邮箱：");String cyx = sc.next();String a = lhm.get(cyx);System.out.println(a);sc.close();}}
