An example of stack and queue in Java data structure

Stack and queue are two important linear data structures, which store data in a specific range of storage units. Compared with linear tables, their insertion and deletion operations receive more constraints and restrictions, which is also called restrictive linear table structure. Stack is FIFO and queue is FIFO. However, some data structures queue data queues according to certain conditions. At this time, the queue belongs to a special queue and does not necessarily follow the above principles.

Implementation stack: array and linked list are used to realize stack

Linked list method:

Implementation queue: same as stack

Linked list method:
