What is hashing in Java? Explain with example

The hashing technique is used to efficiently find or store an item in a large collection of items without the need to go through every item. The key is the hash value, and the object is the value the key maps to.

For example- if we have a list of 10,000 items and we want to check if the given item is on the list or not.

What is the advantage of hashing in Java?

Hashing functions are used to check the integrity of a file. We can compare the content of two files without the need to open them. With the help of the hashing function, the search operation in data structure has become faster. Hence, as more security algorithms and protocols use hashing, it plays a vital role in data security. They convert the data into shorter fixed-length values or keys representing the original string sent over the network.

Why is Hashtable used in Java?

The Hashtable in java is used to store the key or value pairs. A hash table consists of two major components: a bucket array and a hash function.
