Go to concurrenthashmap 2

Go deep into concurrenthashmap 1 and have introduced the basic concurrenthashmap structure, segment composition, hashentry composition, and creation of concurrenthashmap.

This article focuses on putting elements into concurrenthashmap, that is, the put (K key, V value) method.

Concurrenthashmap put a key. The simplified steps of value are as follows:
1. Take the hash value of the key and calculate the subscript In the stored segment array.
2. Find the subscript of the segment array, retrieve the segment, and calculate the array subscript that needs to be stored in the hashentry of the segment.
3. Finally, put the key and value
