If we want to become a Java development engineer or even an architect, we need to meet some conditions, master Java technology, and not simply participate in Java training to become a Java engineer. We still need to forge iron and we need to understand the truth, especially if we want to become a high-paying Java engineer. Not only "hard" skills but also certain "soft" skills are required.
So what technologies do Java engineers need to master to make it easier to get a high salary? Let's take a look:
1. Java technical ability
Having certain Java technical skills is the key to our successful interview, so interviewing Java engineers requires certain technical skills, which is also a factor considered by the company.
2. Java foundation
An understanding of the fundamentals of the Java programming language.
Knowing how to code is great, but knowing the reasoning behind the code and/or the algorithm you choose will make you stand out from the crowd.
3. Mainstream programming tools
Today, the truth is, you can't be a know-it-all person. You have to choose the tools you want to master. Sometimes this is determined by the working environment, but it is also a good choice to do as follows:
Build tools: Maven or Gradle.
SCM: Git (not GitHub. Very different).
Build automation: Jenkins.
IDE: Netbeans or Eclipse - not only for writing code, but also for refactoring and debugging code from within the IDE. I meet a lot of developers who don't know how to debug from their favorite IDE.
Bug tracking: Bugzilla or Jira.
4. Mainstream programming Java framework
Spring MVC for web development
Knowledge of JSF
5. Application server
All Java developers should know how to deploy in Apache Tomcat.
When Glassfish development stopped, the next best thing was JBoss WildFly.
6. Cloud development
Get a free account on Amazon EC or PaaS.
Another option from Amazon is Red Hat OpenShift.
7. Cognitive skills
Having a solid understanding of the Java programming language and various tools is naturally a good thing, but your employer/client will also evaluate you on the following aspects.
8. Communication
Communication is the key to everything we do well. We have to interact with the environment around us, both in our private and professional lives. It's not just the ability to put words together, but also how to communicate the problems we face, or come up with solutions to those problems. A great communicator knows how to express himself in front of various groups; remember, what is obvious to you, may not be so from the perspective of others.
9. Problem solving
Developers are problem solvers as well as philosophers and thinkers. Don't be the kind of programmer who only writes code and doesn't participate in discussions on how to solve problems. Don't be the kind of programmer who just says "tell me what to build and I'll build it, don't ask me if this is the best way to do it".
10. Team spirit
Whether pair programming or a large project, all developers work as part of a team. You need to be committed to the team's goals and objectives. Help mentor junior members, or help struggling team members overcome obstacles. Don't have that "I'm here to just do my job and go home" attitude. Be part of the team. You don't need to be a "team clown" or go out and participate in team activities all the time, but be part of the team.
11. Teach yourself Java
This is a very important skill; the ability to learn new skills on your own time. Don't always wait for the company to provide you with training. You need to learn new technologies by yourself and improve your level in related fields. From front-end development to architectural patterns, there is always something new to learn. Read blogs and articles, or try to learn some new trade-related skills. What you learn can open up new apexes for your career.
For working Java practitioners, it is very important to constantly strive to absorb new knowledge and keep up with the pace of Internet progress. In order to help you study systematically and review the core knowledge points at each stage, I have summarized the Java core knowledge advanced series question bank in this article. My friend has used it to successfully switch to Ali and got 26K.
