- Method Detail
  - add
```
boolean add(float element)
```
    Appends the specified element to the end of me (optional operation). Returns true iff I changed as a result of this call.
    If a collection refuses to add the specified element for any reason other than that it already contains the element, it must throw an exception (rather than simply returning false). This preserves the invariant that a collection always contains the specified element after this call returns.
    
    Specified by:
    
    add in interface FloatCollection
    
    Parameters:
    element - the value whose presence within me is to be ensured
    
    Returns:
    true iff I changed as a result of this call
    
    Throws:
    
    UnsupportedOperationException - when this operation is not supported
    
    IllegalArgumentException - may be thrown if some aspect of the specified element prevents it from being added to me
  - add
```
void add(int index,
       float element)
```
    Inserts the specified element at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices.
    
    Parameters:
    index - the index at which to insert the element
    element - the value to insert
    
    Throws:
    
    UnsupportedOperationException - when this operation is not supported
    
    IllegalArgumentException - if some aspect of the specified element prevents it from being added to me
    
    IndexOutOfBoundsException - if the specified index is out of range
  - addAll
```
boolean addAll(int index,
             FloatCollection collection)
```
    Inserts all of the elements in the specified collection into me, at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices. The new elements will appear in the order that they are returned by the given collection's iterator.
    
    Parameters:
    index - the index at which to insert the first element from the specified collection
    collection - the FloatCollection of elements to add
    
    Returns:
    true iff I changed as a result of this call
    
    Throws:
    
    UnsupportedOperationException - when this operation is not supported
    
    IndexOutOfBoundsException - if the specified index is out of range
  - equals
```
boolean equals(Object that)
```
    Returns true iff that is an FloatList that contains the same elements in the same order as me. In other words, returns true iff that is a FloatList that has the same size as me, and for which the elements returned by its iterator are equal (==) to the corresponding elements within me. (This contract ensures that this method works properly across different implementations of the FloatList interface.)
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    that - the object to compare to me
    
    Returns:
    true iff that is an FloatList that contains the same elements in the same order as me
  - get
```
float get(int index)
```
    Returns the value of the element at the specified position within me.
    
    Parameters:
    index - the index of the element to return
    
    Returns:
    the value of the element at the specified position
    
    Throws:
    
    IndexOutOfBoundsException - if the specified index is out of range
  - hashCode
```
int hashCode()
```
    Returns my hash code.
    The hash code of an FloatList is defined to be the result of the following calculation:
```
 int hash = 1;
 for(FloatIterator iter = iterator(); iter.hasNext(); ) {
   float value = iter.next();
   hash = 31*hash + (int)(value ^ (value >>> 32));
 }
```
    This contract ensures that this method is consistent with equals and with the hashCode method of a List of Floats.
    Overrides:
    
    hashCode in class Object
    
    Returns:
    my hash code
  - indexOf
```
int indexOf(float element)
```
    Returns the index of the first occurrence of the specified element within me, or -1 if I do not contain the element.
    
    Parameters:
    element - the element to search for
    
    Returns:
    the smallest index of an element matching the specified value, or -1 if no such matching element can be found
  - iterator
```
FloatIterator iterator()
```
    Returns an iterator over all my elements, in the appropriate sequence.
    
    Specified by:
    
    iterator in interface FloatCollection
    
    Returns:
    an iterator over all my elements.
  - lastIndexOf
```
int lastIndexOf(float element)
```
    Returns the index of the last occurrence of the specified element within me, or -1 if I do not contain the element.
    
    Parameters:
    element - the element to search for
    
    Returns:
    the largest index of an element matching the specified value, or -1 if no such matching element can be found
  - listIterator
```
FloatListIterator listIterator()
```
    Returns a bidirectional iterator over all my elements, in the appropriate sequence.
  - listIterator
```
FloatListIterator listIterator(int index)
```
    Returns a bidirectional iterator over all my elements, in the appropriate sequence, starting at the specified position. The specified index indicates the first element that would be returned by an initial call to the next method. An initial call to the previous method would return the element with the specified index minus one.
    
    Throws:
    
    IndexOutOfBoundsException - if the specified index is out of range
  - removeElementAt
```
float removeElementAt(int index)
```
    Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.
    
    Parameters:
    index - the index of the element to remove
    
    Returns:
    the value of the element that was removed
    
    Throws:
    
    UnsupportedOperationException - when this operation is not supported
    
    IndexOutOfBoundsException - if the specified index is out of range
  - set
```
float set(int index,
        float element)
```
    Replaces the element at the specified position in me with the specified element (optional operation).
    
    Parameters:
    index - the index of the element to change
    element - the value to be stored at the specified position
    
    Returns:
    the value previously stored at the specified position
    
    Throws:
    
    UnsupportedOperationException - when this operation is not supported
    
    IndexOutOfBoundsException - if the specified index is out of range
  - subList
```
FloatList subList(int fromIndex,
                int toIndex)
```
    Returns a view of the elements within me between the specified fromIndex, inclusive, and toIndex, exclusive. The returned FloatList is backed by me, so that any changes in the returned list are reflected in me, and vice-versa. The returned list supports all of the optional operations that I support.
    Note that when fromIndex == toIndex, the returned list is initially empty, and when fromIndex == 0 && toIndex == size() the returned list is my "improper" sublist, containing all my elements.
    The semantics of the returned list become undefined if I am structurally modified in any way other than via the returned list.
    
    Parameters:
    fromIndex - the smallest index (inclusive) in me that appears in the returned list
    toIndex - the largest index (exclusive) in me that appears in the returned list
    
    Returns:
    a view of this list from fromIndex (inclusive) to toIndex (exclusive)
    
    Throws:
    
    IndexOutOfBoundsException - if either specified index is out of range
