A hash table (also called a hash table) is a data structure that is directly accessed based on the key value. That is to say, It maps the key value to a location in the table to access records to speed up the search. This ing function is called a
This chapter introduces the concept of hash table, the design of hash function and the processing of hash conflicts. The hash list is similar to the dictionary directory, the found element has a key corresponding to it, in practice, hashing

In the Java programming language, the most basic structure is two kinds, one is an array, one is the analog pointer (reference), all the data structure can use these two basic structure constructs, HashMap also. When the program tries to put
Some of the most critical aspects of a hash table are:
Access via key (calculates key by hash function)
Mapped to data structures (the storage structure of the hash table itself)
Processing of mappings (conflict or collision
