问题描述

I have a Map object which has COM-20 HELLO as key and My name as value.我有一个 Map 对象，它的键是COM-20 HELLO ， My name是值。

Is there any way to get this object by indicating that I want the key that contains COM-20 without the HELLO有没有办法通过指示我想要包含COM-20而不带HELLO的密钥来获取此对象

Thanks.谢谢。

Keys should be unique, if you have a map with keys like: COM-20 HELLO1 and COM-20 HELLO2 what should it return?键应该是唯一的，如果你有一个带有像这样的键的映射：COM-20 HELLO1 和 COM-20 HELLO2 它应该返回什么？ both of them?两个都？ It is not possible.这不可能。
