Using removeLast and removeFrist to simulate heap and stack, lastfrist

/*

* Not long ago, I decided to learn Java by myself and pay attention to many public accounts and microblogs. A few days later I saw a joke:

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

* I said, "No, our bed is a queue. You have to go to bed first...

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

* Then, I put my foot on my ass.

* At that time, I read comments, saying that programmers and couples had a lot of fun, and I also checked the stack knowledge online,

* Not professional in computer science, but also in the fog. Today is the second round of basic knowledge Review,

* If you have a method to simulate a stack on the consumer list, you can get started to understand the true meaning of this joke,

* I feel more and more happy with the charm of the programming language.

PutOut: I went to bed after my wife, but I had to get out of bed.
