HASMAP OF ALL WORDS IN DICTIONARY JAVA CODE

* value to be associated with the specified key

* key with which the specified value is to be associated * map previously contained a mapping for the key, the old value is * Associates the specified value with the specified key in this map.

Now look at code implementation of put() method: How HashMap.put() methods works internallyД«efore going into put() methodвЂ™s implementation, it is very important to learn that instances of Entry class are stored in an array.

We will try to understand the need of these fields as we go forward.Д¤. key has been marked as final and two more fields are there: next and hash. Surely Entry class has key and value mapping stored as attributes. HashMap has an nested static class Entry, which looks like this: So, there must be some mechanism in HashMap to store this key-value pair. Read More : Working with hashCode and equals methods in javaДЄ map by definition is : вЂњAn object that maps keys to valuesвЂќ. This function produces hash code by typically converting the internal address of the object into an integer, thus producing different hash codes for all different objects. In other words, two equal objects must produce the same hash code consistently.вЂќДЄll objects in Java inherit a default implementation of hashCode() function defined in Object class. вЂњHash function should return the same hash code each and every time when the function is applied on same or equal objects. Hashing in its simplest form, is a way to assigning a unique code for any variable/object after applying any formula/algorithm on its properties.ДЄ true hash function must follow this rule вЂ“ Now before answering it, one must be very sure to know at least basics of Hashing. If anybody asks me to describe вЂњ How HashMap works?вЂњ, I simply answer: вЂњ On principle of HashingвЂњ. Here we will discuss hashmap internal implementation analysis. But if you are new to concept, follow official java docs. I am assuming that if you are interested in the internal working of HashMap, you already know the basics of HashMap. Learn how HashMap works internally in Java language.
