What do you need to learn about Java development?

With the development of technology and market needs, many friends want to switch to Java development, but they are troubled by not knowing what to learn. They always find a lot of information, but it is never systematic enough. Then to do Java development, the content required for transformation learning is:

The first stage, Java SE basics:

Java environment construction, Java process control statements-for loop, switch selection Judgment, loop nesting, array copy, multi-dimensional array, final keyword, constructor call, class access permissions and paths, advanced object-oriented features, Java exception handling, Set, Map, List interfaces and interface implementation classes, Java threads , synchronous blocking, Java IO stream, file operations, copying, reading, writing, deleting, etc.

The second stage, JavaWeb:

Of course, what is inseparable from the learning process is to form your own programming thinking. When you encounter problems, you can come up with your own solutions. I hope sharing can help friends in need. If you want to stand out among the many IT workers, you need to have advanced skills, and learning to add value is essential. The journey of learning requires persistence.
