Hash Table is the optimal in this case. So simple and quick.

Huh. Just saying Hash Table won't do. How would you implement getRandom() in O(1)?

When you say everything is preferably O(1), are you just saying that faster is better? Clearly "contains" can't be O(1) unless its probabilistic (or unless the data structure is defined to contain at -most O(1) elements...)

Yes, typically people forget hashtable are only expected O(1). But, being a pain in the ass pedant about it is not going to get you the job. (Comment not aimed at you ZSG, just a general comment).

The assumption is you have a great hash function (like a perfect hash function).

Carry on.

The answer is a LinkedHashMap which maintains the order in which elements are inserted. Regarding Random is easy : Generate a random number between 0 and Size and do a get(randomnumber)
