Java language implementation of data structure stack code details

Recently, I reviewed the data structure and implemented the stack myself. Stack is a way to restrict the insertion and deletion of tables in only one location. The most basic operation is to enter and exit the stack. Therefore, it is also called "first in and then out" table.

First, understand the concept of the following stack:

A stack is a linear table that is restricted to insert and delete operations only in the header. Sometimes it is also called LIFO (last in first out table). To understand this concept, we must first understand the original meaning of "stack", so as to grasp the essence.

"Stack" refers to the place where goods are stored or passengers stay, which can be extended to warehouse and transfer station. Therefore, when introduced into the computer field, it refers to the place where data is temporarily stored. Therefore, there is the saying of entering and leaving the stack.

The implementation method is as follows: firstly, an interface is defined, and then the linear stack and chain stack are realized through this interface. The code is relatively simple, as follows:

Linear stack: implemented as an array.

Chained stack: realized through single linked list.

Learning is still in progress and will continue to update the code in the future.

This is all about the detailed explanation of the data structure stack code in Java language. I hope it will be helpful to you. Interested friends can continue to refer to other related topics on this site. If there are deficiencies, please leave a message to point out. Thank you for your support!
