To be a great Java developer, knowledge of the programming language is not sufficient. You must be aware of all Java programming and coding features & functionality to build a good application. In the year 2019, the demand for innovative web applications is on the rise and to meet the needs the same level of Java programming skills is not sufficient. Since Java is one of the most popular programming languages, so be on the top you have to be different from the competition.
So, if you are looking for tips to get better at Java, then you have reached the right place. Here, we will talk about a few impressive tips to be a great Java Developer in 2019. Having skills in new updates in Java is very important such as Cloud Native, Kotlin, and Design Patterns.
1. Build Strong Base in OO Principles
For a Java developer, a strong knowledge of object-oriented programming is necessary. Without having proper skills on OOPS, one can’t know the implementation of an object-oriented programming language. If you are not aware of what OOPS is, even though you are implementing the OOP language, the coding of yours is in a procedural way. Just knowing the principle definitions will not help at all. Proper knowledge regarding the approach to apply those principles in a different OO way is necessary. So, one should have a proper knowledge of the object modeling, inheritance, encapsulation, polymorphism, and design patterns.
2. Explore Spring Framework
For every application development work, this Java platform is important. It helps the developers to build web applications from Plain old Java objects and also beneficial for the programming model. Nowadays, most of the development companies use Spring frameworks like Spring MVC, Spring Cloud and Spring Boot for development work. To be a great Java Developer it is important to be familiar with all the Spring platforms and its benefits like making a method to execute in the database transaction, a remote procedure, and management operation.
3. Improve Your Testing Skills
You will experience advanced testing skills in every expert Java programmer. It is a big distinguishing factor among the good Java programmer and average Java programmer. An expert Java developer is skilled to write unit tests for their code, this process helps in validating the code results in behavior testing. If you are a Java developer, please make sure the testing skills are also present in you like unit testing, automation testing, performance testing, and integration testing. Expert Java developers have experience with code as well as improve their skills on software unit tests to ensure the logic they have is perfect. Beginners can begin with Junit latest version, which is easy as well as powerful.
4. Knowledge of Design Patterns
If you are an experienced software developer, knowledge of Design Patterns importance in Software Development is a must. This basically helps to build a relation between the classes and the object. A systematic process of the objects and classes naming helps in handling the recurring issues in the object-oriented systems. Every professional Java Developer knows and implements design patterns in their code to build a flexible and changeable application.
There are two objectives of the design pattern:
# To understand the application problem and connect with it in some manner.
# Reuse of old design in a more usable way for future purposes.
# Whether you work for a company or as a freelance developer, you must have an in-depth knowledge of the design patterns.
5. Learn JVM Languages
It is always beneficial to learn a new language for the personal and professional benefit, and in the same manner, knowing the programming languages in addition to Java help in Java application development. Kotlin is a highly recommended programming language that runs on the Java virtual machine and is easy to compile to JavaScript source code. Java developers must know JVM languages, like Scala, Groovy, and Kotlin to be a professional developer. By knowing new programming languages, you can easily compare the benefits and disadvantages in a better manner, which will boost to write better code. Besides, it will also help in Android app development work.
6. Be An Expert in Java Libraries
Java has a huge collection of libraries and APIs that build its ecosystem. It is not expected from a developer to be proficient in all libraries, but a few libraries are crucial to understanding. Let’s find out which are necessary:
# Java Standard Libraries
# JHipster
# Maven
# Apache Commons
# Guava
# Google-gson
# Hibernate-ORM
# Mockito
# Junit
# Log4j and Slf4j
Wrapping Up:
If you want to be an expert in Java language and value learning new versions and coding skills, then explore the latest Java features, in addition also learn new programming languages to improve your skill. Of course, knowing everything at once is not possible at all, so start picking one and slowly move to the next. The best would be to learn Java latest version features, as for any application development work, a good knowledge as well as working experience is necessary.
