# <init>

Creates a new empty HashSet with the specified initial capacity.

Capacity is the maximum number of elements the set is able to store in current internal data structure. When the set gets full by a certain default load factor, its capacity is expanded, which usually leads to rebuild of the internal data structure.

### Parameters

`initialCapacity`

- the initial capacity of the created set.
Note that the argument is just a hint for the implementation and can be ignored.

### Exceptions

`IllegalArgumentException`

- if initialCapacity is negative.

Creates a new empty HashSet with the specified initial capacity and load factor.

Capacity is the maximum number of elements the set is able to store in current internal data structure. Load factor is the measure of how full the set is allowed to get in relation to its capacity before the capacity is expanded, which usually leads to rebuild of the internal data structure.

### Parameters

`initialCapacity`

- the initial capacity of the created set.
Note that the argument is just a hint for the implementation and can be ignored.

`loadFactor`

- the load factor of the created set.
Note that the argument is just a hint for the implementation and can be ignored.

### Exceptions

`IllegalArgumentException`

- if initialCapacity is negative or loadFactor is non-positive.

`<init>(elements: Collection<E>)`

Creates a new HashSet filled with the elements of the specified collection.
