Exercise 1 • Create a class that sorts a list in ascending order. Make use of the Collections method sort • The list should be a list of Strings. • Test your code with {“Hearts”, “Diamonds”, “Clubs”, “Spades”} • Before and after the sort, use the implicit call to the list’s toString method to output the list contents. Exercise 2 • Create a class with the same requirement as in Exercise 1, but the sort should be in descending order • Make use of the Comparator interface • Make use of the static collection method reverseOrder

Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.
