Introduction to methods of simulating stacks

/*

*Not long ago, I decided to learn Java by myself and followed a lot of public accounts, Weibo, etc. A few days ago, I saw a joke:

* The child cried at night, and my wife asked me to go check it out.

*I said: "No, our bed is a queue. The bed you get on first has to get out of bed first...

*My wife said: NO NO No, it is a stack.

* Then he kicked me in the butt

* At that time, I read the comments and they all said that programmer couples have more fun, and I also checked the stack online. Knowledge,

* I am not a computer major, so I can only see it in the fog. Today is the second round of review of basic knowledge,

* There is a way to simulate a stack on LinkedList, so let’s get started. After a while, I understood the true meaning of this joke.

* I feel more and more the charm of programming language, and I am happy. ##

PutOut：
我在老婆之后上床却要下床哄熊孩子
老婆先上床却要下床哄熊孩子
