Scientific applications. Java also has very large applications in scientific applications, including natural language processing. The main reason is that Java is better than other languages in terms of security, portability, maintainability, and concurrency.

Java programming language in the domestic computer technology field is very high usage rate, is the current technology application, job recruitment relatively the most technical direction. Especially since we entered the data age, Java's strong support for big data technology has made Java programming language a popular language for program developers again.
