WebThe contains () method calculates the hash (O (1)), indexes into the hashtable (O (1)) and verifies their equality (O (1)). Therefore the complexity is O (1). Due to hash collisions, the indexing step may have to probe a few subsequent elements sharing the same hash, which in worst case can be O (n), but this is very unlikely. 2 phyex • 1 yr. ago WebThe following example demonstrates how to create and populate two HashSet objects.
