Показать описание
HashMap GetOrDefault
GetOrDefault: Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.
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.
