rem
@Deprecated public boolean rem(double k)
Deprecated.Description copied from class:AbstractDoubleCollection
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()
