Xiaobai getting started with Java enterprise development, learning technology route sharing

foreword

There are mainly several types of learning and development in the social population. One is based on technology for a living, the other is hobbies, and the other is technical assistance for work.

This article is mainly provided to those who are ready to learn programming and enter the programming industry. I hope that this article can provide everyone with a learning route to realize their own life value.

suitable for the crowd

Senior graduates; students who are about to change careers and enter the IT industry.

Course objectives

Getting started with JAVA development from zero foundation, the reason for choosing Java development is that Java is the most popular programming language today, and it is also the most used IT job, with a high salary ratio and the most skilled positions. To achieve independent development, framework construction, and truly integrate into enterprise development work.
