Can we use an object as a key for a hashmap in java ? Immutability allows you to get same hash code every time, for a key object. In this tutorial, learn how to use HashMaps in Java with example. Compares an Object with the map for equality.

Retrieve the value of the requested key. In this article we will discuss how to search into a Map by value and fetch associated keys to the given value. Suppose we have a map of string.

The Map provides method signatures including get () , put() , size () , or isEmpty().

V get (Object key), This method returns the object that contains the value associated with. V newValue = remappingFunction. Getting Set of keys from HashMap.

Note: A Groovy map is an instance of java. We can get all the values in a map as a list def map1 . Using put , we would first have to get the value from the map , sort the . Key, containsValue, size,. A Map has key and value and we can get all keys and values as List. Object get (Object k):This method is used to return the value associated with the key k.

Object key ) - returns the value associated with specified key in this hash map ,. And the get (), put() methods in Map interface are used to retrieve and store values into a map. Java Map is a part of collections framework. Returns the string representation of this map.
