remove
public boolean remove(char ok)
Description copied from interface:CharSet
Removes an element from this set.Note that the corresponding method of a type-specific collection is
rem()
. This unfortunate situation is caused by the clash with the similarly named index-based method in theList
interface.- Specified by:

rem
@Deprecated public boolean rem(char k)
Deprecated.Description copied from class:AbstractCharCollection
Removes a single instance of the specified element from this collection, if it is present (optional operation).Note that this method should be called
remove()
, but the clash with the similarly named index-based method in theList
interface forces us to use a distinguished name. For simplicity, the set interfaces reinstatesremove()
.This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.
