（于敏、王大珩（héng）、王希季、朱光亚、孙家栋、任新民、吴自良、陈芳允、陈能宽、杨嘉墀（chí）、周光召、钱学森、屠守锷、黄纬禄、程开甲、彭桓武，王淦（gàn）昌、邓稼先、赵九章、姚桐斌、钱骥、钱三强、郭永怀）。 设计实现一个代号对应名字的猜字系统，需要实现当猜测失败后，随机出相应的提醒，提醒包括首字的笔画，总笔画，首字拼音字母等其中之一。请使用java编写

好的，这是一个简单的 Java 实现，您可以参考一下：

import java.util.HashMap;
import java.util.Map;
import java.util.Random;
import java.util.Scanner;
