Everyone is learning Java development. What is the advantage of Java language?
As the most widely used language in the programming world, Java language has become the first choice for everyone to program. Some people may just hear that Java has a good prospect, Java is better for finding a job, Java language has always been in the top three on the TIOBE rankings, etc., but what is Java good for?
Today's graduates all want to get a good job, good salary, and a job with development prospects. The IT industry is very popular among students because of its high salary and development scenarios.
Why learn Java language
Java language is an object-oriented programming language that is easy to understand. It also omits the incomprehensible concepts of multiple loading, pointers, etc. And realizes automatic garbage collection, which greatly simplifies program design. Furthermore, there are many learning materials for Java, and many learning materials on the Internet are also one of the reasons for everyone to learn Java. In addition, there are also free Java video courses provided by some training institutions. With these learning materials, it is enough to get started.
Cross-platform is the biggest advantage of Java. Java runs on the JVM (Java Virtual Machine), as long as the JVM is installed on any platform. Java just works. It is built on top of the operating system and shields the underlying differences. Really realized "Write once, run anywhere".
Programming in Java is also safer. There are no pointers in the Java language, so there is no way to directly access memory. In addition, Java is not prone to memory leaks. Java has built-in support for multi-threading, which can easily implement multi-threading functions in the program. Unlike other languages that do not support multithreading, multithreading needs to be invoked by calling the multithreading capabilities of the operating system.
As long as you master the basics of Java, you can be competent for the work of junior programmers. Java programmers can have three advanced directions, namely Android mobile terminal development (hereinafter referred to as Android), Web development (hereinafter referred to as Web) and communication development. At this time, the three main directions are currently mainstream.
With the continuous improvement of knowledge and skills, after reaching the level of advanced programmers, you can choose to continue your studies in the programming industry, or turn to requirements analysis or product management.
The master leads the door, and the practice depends on the individual. As long as the foundation is solid and the entry is completed, it will be easier to learn in the future. If you want to learn Java programming well, you must first understand the concept of object-oriented, which is very important. After roughly understanding the concept of object-oriented, you should have learned some Java syntax and some API usage. After that, it is necessary to learn I/O and streams (Stream), as well as multi-threaded programming and network programming. After the foundation of the series is completed, you need to get in touch with the database and JDBC. You don't need to have an in-depth understanding of the database, you can create tables and query table data.
