Preface
As a newbie who is just getting started, I have a little understanding of the Java language. The process of learning is like a blind person touching the elephant. The passion of learning at the beginning is gone, and I slowly become confused. I don’t know if what I learned will be useful in the future. Know how far you have to learn to go out and make money to support your family.
1. Java Foundation (JavaSE)
In order to give myself a clearer understanding of the Java language from a basic learning framework from the beginning of the learning period, I deliberately spent an afternoon on the Internet to organize a rough route, if the barriers are average, one by one knowledge point to overcome, and finally achieve The final goal.

to sum up
There may be many people who want to take shortcuts like me-don't want to spend time on the basis of Java and directly learn the knowledge used in work.
But the foundation really cannot be skipped, and the subsequent Java-related technical content will be extended on these foundations. Such as: object-oriented, IO stream, collection, common API, these are often used in the future.
Only if you have a solid foundation can you go further. Otherwise, the difficulty of the content will increase afterwards. It is easy to find that you don't understand at all and there is no way to continue learning.
Take action with me, spend a month to lay a solid foundation for yourself, and then start a charge towards even more rare targets!
