Get Multiple Keys From Value Using the Stream API in Java Hashmap is an essential part of Java and gives us the power of flexibly work on our data by using the key-value pair method. The value is attached to the
getKey(); System.out.println(key); } } } Output: One Two Three In this code, we again create a HashMap and fill it with key-value pairs. The entrySet() method provides a Set of entries, which we can loop through. Each entry allows us to call getKey() to retrieve the key....
