Method Detail

remove

public boolean remove(char k)

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 the List interface.

rem

@Deprecated
public boolean rem(char k)

Deprecated.

Description copied from interface: CharCollection

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 the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().
