We can remove all key and value mapping from hashmap using clear () method or remove () method through iterator on hashmap. If a value is provided then the entry will only be removed if its value. The java.util.hashmap.remove() is an inbuilt method of hashmap class and is used to remove the mapping of any particular key from. For removing all mappings from a hashmap in java we can use various approaches : Hashmap hm = new hashmap(); The remove() method removes an entry with a specified key from the map. Assuming your set contains the strings you want to remove, you can use the keyset method and map.keyset().removeall(keyset);. First, let us create a hashmap. Note you'll get an exception if you try. In this example we are going to see how to remove all the mappings from hashmap. You have to iterate through the list, look at the value object, and conditionally do the remove.
