structure in Java that stores key and value pairs. The map is aninterfacepresent in theCollectionhierarchy. These keys are unique so, no duplicate keys are allowed; however, the variables mapped to the key can have duplicate values. Classes likeHashMap,LinkedHashMap, andTreeMapimplement theMap...

To compare items based on their values, we must create acomparator. While using this approach, we have to keep in mind that we can store duplicate values. See the code below. importjava.util.Collections;importjava.util.Comparator;importjava.util.HashMap;importjava.util.LinkedHashMap;importjava...
HashMap is indecipherable crap. :( Visual Studio 2017 has natvis for C++. It's not great. I have a lot of complaints. It's way better than Rust's nothing. Mixed Debugging While working on this post I learned something new. I'm somewhat blown away and want to share it. I was ...
The idea of prepared statements is to cache precomputed SQL and expressions in HashMap in memory, so they can be directly used in queries when applicable. Prepared statements adopt MySQL binary protocol for transmission. The protocol is implemented in the mysql_row_buffer.[h|cpp] file, and use...
