#How long does it take to learn Java by yourself?
It generally takes half a year to 2 years to learn Java well.
The prerequisites are as follows:
● If you have basic knowledge of computer science, you can improve your learning efficiency.
● Guidance from people with Java work experience, or training from training institutions.
● There are actual projects to do. When working on projects, you can quickly gain access to new knowledge.
Learning opinions:
1. Watch "Thinking In Java", don't stop watching it just because it is difficult and we are beginners ourselves;
2. Don’t let go of any seemingly simple small programming problems - they are often not that simple, or they can lead to a lot of knowledge points;
3. Talk about fashionable technologies , it is better to keep the outdated technology in mind;
4. One of the best ways to learn programming is to read the source code;
5. Do not think that the book in your hand is at any time It's enough;
6. If you can understand the book, please read it carefully; if you can't understand the book, please read it bravely;
7. Don't expect to read the book for the first time. What can be remembered and mastered - please read the second and third times;
8. Don’t stay in the cradle of the integrated development environment, learn to control the integrated development environment, and learn to use the command line Processing programs;
9. The secret to learning programming is: program, program, program again;
10. Never fail to follow some rules that you are not proficient in just because the program is "small" ——Good habits are cultivated, not remembered once;
11. Don’t be confused by J2SE, J2EE, J2ME, remember, you only need JDK
12. Impetuous It’s easy for people to say: If you can’t speak XX language well, you should learn YY; - it’s you who can’t speak it! ?
13. Impetuous people tend to ask: What should I learn? - Don’t ask, just learn;
14. Impetuous people tend to ask: Does XX have a way to make money? ——I suggest you go rob a bank;
15. Impetuous people tend to say: I want the Chinese version! I can't speak English! --no? Learn!
16. Impetuous people tend to ask: Which one is better, XX or YY; - Let me tell you, both are good - as long as you learn;
17. There are two types of impetuous people: a) People who just watch without learning; b) People who only learn without persisting;
18. Save all the programs you have written - that is one of your best accumulations;
19. Please don’t be an impetuous person;
20. Please love JAVA!

Java is widely used in enterprise-level applications because of its platform independence. 1) Platform independence is implemented through Java virtual machine (JVM), so that the code can run on any platform that supports Java. 2) It simplifies cross-platform deployment and development processes, providing greater flexibility and scalability. 3) However, it is necessary to pay attention to performance differences and third-party library compatibility and adopt best practices such as using pure Java code and cross-platform testing.

Java is suitable for developing cross-server web applications. 1) Java's "write once, run everywhere" philosophy makes its code run on any platform that supports JVM. 2) Java has a rich ecosystem, including tools such as Spring and Hibernate, to simplify the development process. 3) Java performs excellently in performance and security, providing efficient memory management and strong security guarantees.

JVM implements the WORA features of Java through bytecode interpretation, platform-independent APIs and dynamic class loading: 1. Bytecode is interpreted as machine code to ensure cross-platform operation; 2. Standard API abstract operating system differences; 3. Classes are loaded dynamically at runtime to ensure consistency.

The latest version of Java effectively solves platform-specific problems through JVM optimization, standard library improvements and third-party library support. 1) JVM optimization, such as Java11's ZGC improves garbage collection performance. 2) Standard library improvements, such as Java9's module system reducing platform-related problems. 3) Third-party libraries provide platform-optimized versions, such as OpenCV.

The JVM's bytecode verification process includes four key steps: 1) Check whether the class file format complies with the specifications, 2) Verify the validity and correctness of the bytecode instructions, 3) Perform data flow analysis to ensure type safety, and 4) Balancing the thoroughness and performance of verification. Through these steps, the JVM ensures that only secure, correct bytecode is executed, thereby protecting the integrity and security of the program.
