Maps: key based arrays Sets: index based arrays
returns an instance of a Map.
returns an instance of a Set.
The Arrays class is an abstract class whose methods:
- are
public static - take in a reference to an array
- take in at least one callable value, or an array of callable values
- return a new array
- each will not return an array, and will iterate over the original, passing values by-ref, and modifying the original element
