article programming languages java js


An article will show you what language can do ( Introduction )

We learned a lot of languages in University , But it's just the basics , As the saying goes , Master leads in , Cultivation depends on individuals , University teachers are just our guides , If you want to learn more, you have to rely on yourself .

What can language do ?
Easy to live , Optimization experience , Make the world a better place

java and js

What we learned java It might look something like this
 Insert picture description here Of course, inherit What? And threads File input and output streams also learn
But it takes a lot of knowledge to make a system
At present, many companies still have the back end of java Written spring The emergence of the has brought about java Spring of
It also makes it easier to separate the front and back ends



js

.js At the end of the document

<script></script> Internal

Or third party references
Achieve front-end logic interaction, etc
At the beginning, the teacher said html then css( style ) then js( function )
It's like a soldier with flesh and blood (html) Definitely not
We need to give him some armor (css)
Learn some skills, actions and so on (js) That's how it works
Learn it well html,css,js You can build a factory , Mass production fighters
So you have to learn vue 了 ( Or some other front-end framework )
 Insert picture description here
The following figure shows a simple front-end and back-end separation project, and the database is placed on the cloud server
java+vue
Part of the data is dead data
 Insert picture description here
 Insert picture description here  Insert picture description here
java Language —spring boot Provide interfaces to the front end , like u Disks and computers , There's data on the computer , You're going to take the data and process it , First turn on the u The disk is plugged into the computer , So you get the data , How you process data depends on how you use it , Of course, some computer files are encrypted , Token required , It involves the resource security policy group , The same can be said for u Disk encryption , Give Way js Dynamic and so on .













javascript—vue The front frame , What you make is the page you see , Show you the data

A database can be understood as a library for storing data

python

my python What comparison dishes can show is what we learned in class
 Insert picture description here

 Insert picture description here This is used here.
pandas
matplotlib

python There's a very rich library
python
A lot of people will associate it with artificial intelligence ,Python A lot of things have been done

Reptiles , Data cleaning
machine learning
Artificial intelligence
wait
Yes python Interested partners can move on
Don't warm the fire
It must have been clear to all of you





Learning route

Back end :java Study hard — be familiar with jvm—spring—spring boot
Of course, be familiar with maven database ( There are many kinds of , Choose the right )
front end HTML and JS—VUE—uni-app wait

As long as you work hard , The needle becomes an iron rod , come on.

It will be launched later

front end :js introduction vue introduction vue Developing small programs etc.
Back end : java introduction springboot Introduction, etc
The server :mysql introduction Server simple instructions Cloud server running project
python: recommend Don't warm the fire Be sure to see
The use of some plug-ins, etc



The way of university is also in itself , Study hard , Hot blooded youth
