Java: Map Interface and HashMap
Answer
entrySet() allows access to both keys and values.
The entrySet() method returns a set view of the mappings contained in a HashMap. It is often used in a for-each loop to iterate over both keys and values, which is handy when you need to print or process each key-value pair.
