        char removeFirst()
        Retrieves and removes the first element of this deque.
        Returns:
        the head (first) element of this deque.

        Returns:
        the head of this deque.

      • getLast

        char getLast()
        Retrieves the last element of this deque but does not remove it.
        Returns:
        the head of this deque.

      • descendingIterator

        java.util.Iterator<CharCursor> descendingIterator()
        Returns:
        An iterator over elements in this deque in tail-to-head order.

      • descendingForEach

        <T extends CharProcedure> T descendingForEach​(T procedure)
        Applies a procedure to all elements in tail-to-head order.

      • descendingForEach

        <T extends CharPredicate> T descendingForEach​(T predicate)
        Applies a predicate to container elements as long, as the predicate returns true. The iteration is interrupted otherwise.
