Recently, senior code farmers released the List of Languages in China in August 2020. Java is still the most in demand, and the average salary is as high as 14,470 yuan. ** As one of the most widely used languages in the industry, what is the fallback for Java programmers? In other words, as a Java programmer, what can you do when you don’t want to work in a field?
Java application
While many live by the motto, “There is no retreat!” But see this, also have to sigh with emotion Java programmer retreat a lot of, development direction that call a versatile!
- **Android Apps: ** Open any App and their code is still written in Java.
- ** Many international investment banks, such as Goldman Sachs and Citigroup, use Java to write their front – and back-office electronic trading systems.
- ** Website field: ** JINGdong, Taobao, etc
- ** Software development: ** Well-known Java development tools such as Eclipse, MyEclipse, IneteliJIdea and Netbans IDE.
- ** Game Development: ** Typical applications are mobile games
- ** Embedded field: **Java is favored by the embedded field because of its many advantages, and has been a lot of research and development applications.
- ** Big data technology: **Hadoop and other big data processing technologies are all in Java.
The advantages of Java
Java is simple, easy to design, easy to write, and therefore easier to compile, debug, and learn than any other Java. Java is object-oriented for building reusable code in modular programs and other applications. Java is platform agnostic and portable for replication.
Java is a very general-purpose language, so it can be used in many different environments. It also runs on many different platforms, so you can run it on Linux machines, Unix, Mac, Windows, or mobile phones. Therefore, it can be used with almost anything.
Java is a general-purpose programming language, very similar to Python or JavaScript.
The language itself is particularly an object-oriented programming language, so it has similarities with C ++ and C #.
Java is also a platform, which means that Java code can run on any computer with a Java Virtual Machine (JVM). Initially these two things were interchangeable, and the only thing running on the JVM was Java. But since then, many languages have been written to run on the Java platform, such as Scala, Groovy, Ruby called jRuby, Python called Jython, and so on.
Java is a popular language worldwide for a number of reasons:
Java has been around for a long time, so it’s really good. There are a lot of great books, online resources.
There are probably more Java programmers in the world than any other type of programmer, so many people already know Java, so it’s easy to find someone to help and mentor.
Java derives its syntax from C, and many other languages derive their syntax from C, so if you learn Java, it’s much easier to learn languages like Javascript, C #, or C ++.
It is an object-oriented language, so many of the basic concepts you learn in Java can be transferred to other languages.
What’s so hard about learning Java yourself?
** often goes astray: ** does not have a macro understanding of Java and often wastes learning time on points that are no longer popular.
** No one to answer questions waste time: ** For example, environment installation, grammar application often bugs, need to waste a lot of time to troubleshoot vulnerabilities.
** theory full marks lack of actual combat: ** theory will appear high concurrency demand a face meng ratio.
** does not have a systematic understanding of Java theory, and it is difficult to answer the interviewer’s questions properly.
