The java.util.hashmap.remove() is an inbuilt method of hashmap class and is used to remove the mapping of any particular key from. If a value is provided then the entry will only be removed if its value. In this tutorial, we will learn. Checking for key/value existence (containskey, containsvalue) the containskey() method returns true if the hashmap contains a mapping for the specified key. I usually use the keyset's iterator, and then base my condition off the value for that key: We can use the methods provided by the java.util.map interface for entry removal using the key as an input. When the remove() method is called upon a key. Thus, one idea would be to use the key as an identifier to remove an associated entry from the map.
