For loop 在HashMapJava中如何在终端中输入多个键以输出多个值
程序概述：终端询问用户“出了什么问题”，用户给出一个单词“bug”，这是一个键！从hashmapif它是一个键，然后它从终端屏幕中的hashmap输出相应的“值”，否则它会给出一个随机的defaultresponse 问题：如果用户输入'bug and crash'，它将只读取'bug'键并输出相应的值，但我想让它做的是拾取多个关键字并输出相应的值，我该怎么做 下面是这两个类所需的代码 来自测试类的方法For loop 在HashMapJava中如何在终端中输入多个键以输出多个值,for-loop,foreach,hashmap,key,return-value,For Loop,Foreach,Hashmap,Key,Return Value,程序概述：终端询问用户“出了什么问题”，用户给出一个单词“bug”，这是一个键！从hashmapif它是一个键，然后它从终端屏幕中的hashmap输出相应的“值”，否则它会给出一个随机的defaultresponse 问题：如果用户输入'bug and crash'，它将只读取'bug'键并输出相应的值，但我想让它做的是拾取多个关键字并输出相应的值，我该怎么做 下面是这两个类所需的代码 来自测试类的方法 public HashMap<String, String> create
