  1. How to Become a Good Java Programmer To become a good Java programmer, you must learn certain skills that help you in efficient programming and coding. If you are someone who isn’t aware of how to be a good java developer, you need to learn various skills to code. So here I have jotted down certain points that would help you become a better Java programmer and application developer. Always remember a better programmer is always a better Java developer. This article would bring certain points that would help you improve your programming and coding skills which are very important for becoming a java developer. This article basically focuses on the development perspective. This article would be more helpful if you are aware of a few basic things like Coding, Data Structures, algorithms, networking, Protocols, and Object-Oriented Programming. These few tips would give you an insight into the whole scenario. These tips would be helpful for both the java developers dealing with the server-side applications who aren’t involved with web development skills like JSP, JEE, and Servlet and the java developers whose basic job is to write a web application using Java technology.

  2. Why are Java developers are hired for critical software projects? •Java is mainly managed by Oracle now. There is a huge scope for the growth of java when we talk about APIs and platforms. Java’s latest release is edition 11.0.8. •Java is quite popular after C. This is selected by the software developers as the best choice of programming language. •All the android OS uses Java APIs. •It is one of the languages which can be used in both software and web development since it is an open-source code programming language. Here are some tips and suggestions which would help to become a better Java developer: 1. Deep Awareness About the JVM’s Internals If you are someone who is passionate about becoming a Java professional, then you must spend time in attaining knowledge about JVM internals. There are various things we need to know like: •What are the different parts of the JVM? •How do they work? •JIT •JVM options •Garbage Collection •Collectors Awareness about the JVM would help in writing robust and high-performance Java applications. As a learner, you should also learn, how to find the performance bottlenecks.

  3. 2. Gain Knowledge About Design Pattern If you are a software developer, you must be aware of the importance of having knowledge about Design patterns. The basic work of design patterns is to find a relation between classes and objects. Every programmer incorporates design patterns in the code to make it flexible and changeable. The main aim of learning designing pattern is to: 1. Identifying and associating the problem with some pattern. 2. Reusing the pre-existing interface or making the existing design more usable. 3. Gain Knowledge About Spring Framework Most of the companies prefer the developer to learn about spring as they prefer the development using this framework. The various spring framework being used are: •Spring MVC •Spring Boot •Spring cloud •REST APIs •Microservices It helps in making the application more testable, the key requirement of modern-day software. If you are someone who is new at this, it is suggested to learn java and spring to learn an excellent framework. 4. Microservices and Cloud The Java developers should learn about Microservice Architecture and how to create them in the java language. The Spring Framework simplifies microservice development in java as it provides Spring Cloud and Spring boot. The Master Microservices with Spring Boot and Spring Cloud is a good course if you are looking for something to start with.

  4. 5. Learn Unit Testing A good java developer is separated from the average one by their unit testing skills. A professional approach of a java developer writes unit tests for their codes. Java developers have covered a long way, they use several tools for unit testing, integration testing, and automation testing. 6. Knowledge About APIs and Libraries Great java developers have an overall knowledge about the java ecosystem and APIs which form a huge part of it. Java has one of the most popular programming languages which have loads of libraries and APIs which do almost everything. It is impossible to know all of them. But certain key APIs should be known. Examples: •JSON processing APIs like Jackson and Gson. •XML processing APIs like JAXB and Xerces. 7. Knowledge About DevOps Tools As a modern java developer, it is essential to know about DevOps tools. It is essential to be familiar with continuous integration and continuous deployment. As a senior Java developer, it is even more important for setting coding best practices and creating environments, building scripts, and guidelines. 8. Acquire Knowledge About Scala and Kotlin Learning new languages help us in various ways, similarly learning a programming language apart from java helps in java application development. Kotlin is a general-purpose, free, open-source, and statically typed pragmatic programming language designed for JVM and Android that combines object- oriented and functional programming features. In order to become a polyglot developer, java enthusiasts must learn various JVM languages like Scala, Groovy, and Kotlin.

  5. 9. Better Knowledge of IDE Java developers have the best feature that they are very good with their tools. Java developers are expected to know more tools than an average developer but also know their tools. Various important IDE tools for a java programmer are: •Eclipse •NetBeans •IntelliJ IDEA These IDE skills would help reach to next level. Final Takeaways If you want to excel as a java developer and value the coding skills, it is definitely not a golden platter. You need to invest your time and efforts to enhance your skills. It’s a bit tough to follow all the tips, you just need to follow the important ones first. If you learn about IDE first then learning it better would make it a more productive and better java developer in no time. If the focus starts with concurrency and performance, you can move forward and learn more. if you follow 9 above-mentioned tips thoroughly, then you'll surely become a good Java programmer in a reputed mobile application development company. Thanks, and goodluck for your programming career! Suggested Reading: Benefits of Choosing Android As A Mobile App Development Platform
