| + | There also cannot be more members in the set than there is space in the array. It only has as much memory allocated as the array specifies. To make the set larger you would need to make a new array. | ||

| - | A set is a group of unique objects, typically ordered in some way or another. Sets are typically used to test membership of a given value rather than retrieving a specific element. | + | A set is a group of unique objects, typically ordered in some way or another. Sets are typically used to test membership of a given value rather than retrieving a specific element. Sets (at least for us) will typically be stored in Arrays, however they can be stored in a List. |

| + | For example if you want an occurrence to only happen if a specific value is one of 5 different items, you could compare it against a set. Your code can then branch off whether there is a match or not. | ||
