Java basics and java Basics

Java basics and java Basics

This is a full set of Java knowledge I have prepared in my previous lectures. It is applicable to beginners and intermediate and advanced students. You can download it. I think it is more systematic and comprehensive, it can be up to 90% of the learning materials on the market. I hate the casually written information and the people who sell money! Here I will share it for you for free!

I can really learn a lot on this platform! Many people are selflessly offering their wisdom and knowledge.

Hope to help Java learners! If you think it is good, you should give a response in the comments. Thank you.

First, it is very important to establish a development environment. To do well, you must first sharpen the tool. To do any development, you first need to prepare the environment, and then you can make various attempts to build confidence in the process. Beginners are often frustrated by unexpected problems in Environment configuration.
