The codes submitted to Github demonstrate multiple functionalites of the HashMap collection.

A good amount of Hashmap methods were used in our code. Usually in combination with foreach loops.

• put() - This method simply adds an item to the HashMap
• putIfAbsent() - This method allows you to map a value to a key provided the given key isn't already associated with a value.
• replace() - This method replaces the specified value for a specified key.
• remove() - This method removes specified values with the associated specified keys from the map.
• putAll() - This method is used to insert the specified map in the map.
• clear() - This method clears the given mappings to the map
• isEmpty() - This method checks if the HashMap is empty and return true if it is.
• size() - This method returns the size of the Hashmap.

Amongst various other methods.
