Method Detail

getBoolean

public boolean getBoolean(int i)

Description copied from interface: BooleanList

Returns the element at the specified position in this list.

Specified by:

getBoolean in interface BooleanList

See Also:

List.get(int)

rem

public boolean rem(boolean k)

Description copied from class: AbstractBooleanCollection

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().

This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

Specified by:

rem in interface BooleanCollection

Overrides:

rem in class AbstractBooleanCollection

See Also:

Collection.remove(Object)

removeBoolean

public boolean removeBoolean(int i)

Description copied from interface: BooleanList
