public abstract class AbstractIntSet extends AbstractIntCollection implements java.lang.Cloneable, IntSet
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()
).

public boolean remove(int k)
rem()
method
implemented by type-specific abstract Collection
superclass.@Deprecated public boolean rem(int k)
remove()
instead.Note that this method should be called remove()
, but the clash
with the similarly named index-based method in the List
interface
forces us to use a distinguished name. For simplicity, the set interfaces reinstates
remove()
.
Delegates to the type-specific remove()
method
specified in the type-specific Set
interface.
