This Java Challenge will introduce the ConcurrentHashMap class that is useful to use in a multi-thread environment. The ConrrentHashMap can also be used to delete an element inside a for loop for example. The ConcurrentHashMap will synchronize different Threads and, therefore, won’t mess up data.
Without further ado, it’s time for the Java Challenge!
This is it challenger, get prepared for the next Java Challenge, and keep improving your Java skills!
