方法详细资料

peekFirst

public static <E> E peekFirst(List<E> list)

Get the first element of list.

pollFirst

public static <E> E pollFirst(List<E> list)

Remove the first element from list and return it.

peekLast

public static <E> E peekLast(List<E> list)

Get the last element of list.

pollLast

public static <E> E pollLast(List<E> list)

Remove the last element from list and return it.

peekFirst

public E peekFirst()

Get the first element of list.

peekLast

public E peekLast()

Get the last element of list.

pollFirst

public E pollFirst()

Remove the first element from list and return it.

pollLast

public E pollLast()

Remove the last element from list and return it.

removeRange

public void removeRange(int fromIndex,
                        int toIndex)

Expose this methods so we not need to create a new subList just to remove a range of elements. Removes from this deque all of the elements whose index is between fromIndex, inclusive, and toIndex, exclusive. Shifts any succeeding elements to the left (reduces their index). This call shortens the deque by (toIndex - fromIndex) elements. (If toIndex==fromIndex, this operation has no effect.)

覆盖:

removeRange 在类中 ArrayList<E>

抛出:

IndexOutOfBoundsException - if fromIndex or toIndex is out of range (fromIndex < 0 || fromIndex >= size() || toIndex > size() || toIndex < fromIndex)
