Java Docs:
PutIfAbsent: If the specified key is not already associated with a value (or is mapped to null) associates it with the given value and returns null, else returns the current value.
Learn how to use Java HashMaps which is part of the data structures in the Java Collections framework. With HashMaps we can store key and value pairs. We access the elements using their corresponding Keys. It is the Hash table based implementation of the Map interface.
You will learn how Java hashmaps work, how to iterate through a hashmap and various hashmap methods to work with key-value pairs.
We will look at HashMap methods such as get(), put(), containsKey(), putifabsent(), getordefault(), keyset(), remove and replace(), compute() and other HashMap methods.
