Can you tell me what you know about HashMaps?

HashMaps are unordered collections of key-value pairsHashMaps require keys in order to access valuesKeys and values can be of different typesWe can use primitive types within HashMaps

Right! HashMaps are unordered collections of key-value pairs. Keys point to values and can be of a different type but neither of them can be of a primitive type.

Oh noes! HashMaps are unordered collections of key-value pairs. Keys point to values and can be of a different type but neither of them can be of a primitive type.
