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. |
int |
lastIndexOf(float element)

Replaces the element at the specified
position in me with the specified element
(optional operation).
|

public FloatList subList(int fromIndex, int toIndex)
FloatList
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.public boolean equals(java.lang.Object obj)
FloatList
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
an 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.)public int hashCode()
FloatList
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 Float
