🥊 How To Use Equals Method In Java

In Java, it’s particularly important because most of the collections (HashTable, etc.) are based on the equals method. If you put a member of the super class in a hash table as the key and then To implement a hash table, we should use the hash table class, which will map keys to the values. The key or values of the hash table should be a non-null object. In order to store and retrieve data from the hash table, the non-null objects, that are used as keys must implement the hashCode() method and the equals() method. Hashtable produces s863P.
