An abstract class providing basic methods for sets implementing a type-specific interface.
Note that the type-specific Set
interface adds a type-specific remove()
method,
as it is no longer harmful for subclasses. Thus, concrete subclasses of this class must implement
remove()
(the rem()
implementation of this class just delegates to
remove()
).

hashCode
public int hashCode()Returns a hash code for this set. The hash code of a set is computed by summing the hash codes of its elements. -
remove
public boolean remove(char k) Removes an element from this set. Delegates to the type-specificrem()
method implemented by type-specific abstractCollection
superclass. -
rem
Deprecated.Please useremove()
instead.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()
. Delegates to the type-specificremove()
method specified in the type-specificSet
