```
    Creates a new TFloatHashSet instance that is a copy of the existing Collection.
    
    Parameters:
    
    collection - a Collection that will be duplicated.
  - TFloatHashSet

    Parameters:
    
    array - an array of float primitives
- Method Detail
  - iterator
```
public TFloatIterator iterator()
```
    Creates an iterator over the values of the set. The iterator supports element deletion.
    
    Specified by:
    
    iterator in interface TFloatSet
    
    Specified by:
    
    iterator in interface TFloatCollection
    
    Returns:
    
    an TFloatIterator value
  - toArray
```
public float[] toArray()
```
    Returns an array containing all of the elements in this set. If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
    The returned array will be "safe" in that no references to it are maintained by this set. (In other words, this method must allocate a new array even if this set is backed by an array). The caller is thus free to modify the returned array.
    
    This method acts as bridge between array-based and collection-based APIs.
    
    Specified by:
    
    toArray in interface TFloatSet
    
    Specified by:
    
    toArray in interface TFloatCollection
    
    Returns:
    
    an array containing all the elements in this set
  - toArray
```
public float[] toArray(float[] dest)
```
    Returns an array containing elements in this set.
    If this set fits in the specified array with room to spare (i.e., the array has more elements than this set), the element in the array immediately following the end of the set is set to TFloatSet.getNoEntryValue(). (This is useful in determining the length of this set only if the caller knows that this set does not contain any elements representing null.)
    
    If the native array is smaller than the set size, the array will be filled with elements in Iterator order until it is full and exclude the remainder.
    
    If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
    
    Specified by:
    
    toArray in interface TFloatSet
    
    Specified by:
    
    toArray in interface TFloatCollection
    
    Parameters:
    
    dest - the array into which the elements of this set are to be stored.
    
    Returns:
    
    an float[] containing all the elements in this set

public boolean equals(Object other)

    Compares the specified object with this set for equality. Returns true if the specified object is also a set, the two sets have the same size, and every member of the specified set is contained in this set (or equivalently, every member of this set is contained in the specified set). This definition ensures that the equals method works properly across different implementations of the set interface.
