Then, can a set be equal and equivalent?

Equal sets are equivalent, but equivalent sets may not be equal. This was illustrated in the above example where A ~ B, but A ≠ B. Two sets are equal when they have exactly the same elements, and sets are equivalent when a one-to-one correspondence can be set up between the two sets.

Also Know, does HashSet use equals or hashCode? The relation between equals and hashCode is: If equals returns true, then hashCode must return the same value. Otherwise a structure like java. util. HashSet won't find the same bucket and could not guaranty that there are no two equal objects in a HashSet.

Also to know is, what are unequal sets?

Equal and Unequal Sets Two sets X and Y are said to be equal if they have exactly the same elements (irrespective of the order of appearance in the set). Equal sets are represented as X = Y. Otherwise, the sets are referred to as unequal sets, which are represented as X ≠ Y.

What is the difference between equivalent and equal?
