From learning JDK 8 to studying the JVM’s internals, getting more efficient with your IDE, and trying your hand at Kotlin, here is some advice to be a better Java dev.

I often receive emails from my readers about how they can become a better Java developer, what things they should learn, and which area they can work on to become a rockstar Java developer. After answering them individually over the last few years, I thought to jot down a couple of points that I think will make you a better Java programmer and application developer. computer science course computer science jobs computer science binus

If you haven’t read them yet, you can read it after this article, they will help you to improve your programming and coding skill which is essential to becoming a better Java developer. computer science course computer science jobs computer science binus

These tips are equally useful for both core Java developers as well as Java web developers. computer science course computer science jobs computer science binus

1. Learn Java 8

This is the most important thing for a Java developer right now. It’s a good 4 years old and even Java 9 was released 6 months back and people are now talking about Java 10 features. Regardless, I know many programmers who have not written a single line of code using Java 8 features like lambdas and the Stream API. computer science course computer science jobs computer science binus

Unfortunately, most of them are experienced Java developers with good 7 to 10 years of experience under their belt. I understand that at some point in your career, learning becomes slow, but if you don’t act now you will be left behind. computer science course computer science jobs computer science binus

Almost all Java development jobs now require Java 8 skills, and if you don’t have them, it will be very difficult to do well. computer science course computer science jobs computer science binus

2. Learn Spring Framework (Spring Boot)

It’s almost imperative nowadays for a Java developer to learn about Spring, as most companies prefer to do development using Spring frameworks like Spring MVC, Spring Boot, and Spring Cloud for developing a web application, REST APIs, and microservices. computer science course computer science jobs computer science binus

It also promotes best practices like dependency injection and makes your application more testable, which is a key requirement for modern-day software. computer science course computer science jobs computer science binus

3. Learn Unit Testing

If there is one common thing that separates a good Java developer from an average Java developer, it is unit testing skills. computer science course computer science jobs computer science binus

A good and professional Java developer almost always writes unit tests for their code, and if they are really a rockstar developer, you can see that from their code and tests. computer science course computer science jobs computer science binus

Testing has also come a long way, with several tools for unit testing, integration testing, and automation testing available to Java developers. computer science course computer science jobs computer science binus

You can spend a good amount of 2018 honing your testing skills in Java, but for those who are new to the Java world and unit testing, JUnit is the best library to start with. The most recent version (JUnit 5) is both powerful and flexible and every Java developer should know that. computer science course computer science jobs computer science binus
