After learning java, I won't be able to write anything.

I believe that many friends who are learning Java will have this kind of confusion: I have studied Java for a long time and understand the basic grammar, but I just can’t write anything. What should I do? ? Today I will share with you how to do it!

First of all, you need a basic grammar book. Just pretend that you have never learned anything before and start everything from scratch. It’s just the kind used in ordinary universities. After learning the grammar, buy Think in Java and read it several times. Remember,
Secondly, focus on writing more code yourself during the learning process. Writing code yourself is so important to learning a programming language. For example, you can program some Tetris, or a simple student management system.
Finally, after learning the knowledge of Java SE, you can choose the Java EE direction or the Java Me direction. One is for enterprise-level application development, and the other is the mobile phone direction. Now the Java mobile phone direction is still good.

I am working in the direction of JavaEE. If you want to go in this direction, you need to do a good job in the database. You must be very familiar with JDBC programming. Servlet is a technology that can well represent the direction of JavaEE. Be familiar. You can optionally learn the SSH framework. It seems to be very popular now, but many people only know how to use it and don’t know how they implement it. This is not enough. It is recommended that you read the source code implementation of these frameworks based on your ability to use it (this requires you to Very familiar with the basics of Java) and understand the underlying implementation principles of Zhejiang West. When you are looking for a job, talk to the interviewer about this, and people will appreciate you very much.

In addition, you can watch some videos as needed during the learning process, which will be helpful for beginners. You can learn something.

Java implementation "write once, run everywhere" is compiled into bytecode and run on a Java virtual machine (JVM). 1) Write Java code and compile it into bytecode. 2) Bytecode runs on any platform with JVM installed. 3) Use Java native interface (JNI) to handle platform-specific functions. Despite challenges such as JVM consistency and the use of platform-specific libraries, WORA greatly improves development efficiency and deployment flexibility.
