Fields related to computer science, particularly software engineering and development are going to be some of the fastest-growing professional fields in the coming decade. Particularly when it comes to development, you are likely to see an 8% growth in jobs associated with the field over the next few years, as per the Bureau of Labor Statistics. It is only fitting that development has become a lucrative field for many, with a scramble to gain the necessary skills to be a competent developer.
Java is a computer script on which a vast number of development activities are based. If you are looking to build a successful career as a Java developer, you need to gain a few essential skills to be a competent candidate in today’s competitive environment.
Here are a few skills that can help you get a Java developer job in Singapore.
Java 8: The Backbone of Java
Java is the 4th most used programming language in the world. Java 8 forms the backbone of the modern Java system. Even though Java 9 has been released and discussions are ongoing regarding the features of Java 10, Java 8 is pretty much the minimum level of competence you require to be considered for Java developer jobs.
Features of Java 8, such as Stream API and lambdas were extremely convenient and radical for the times during which they were released and are still pretty useful even for the most basic of programs.
The Importance of Unit Testing
Unit testing is among the most important skills a competent Java developer must possess. Unit testing is not merely a professional requirement, but can often be the difference between a good piece of code and a bad one. Today, developers generally do not need to write separate code to test their main code, and can instead use automated tools to assess the veracity of their code.
Learn APIs & Libraries to Succeed
APIs and libraries of Java should be like second nature to a good developer looking to apply for Java developer jobs. With Java, you can carry out a majority of the task assigned to you only if you know the right library or API to refer to. From JSON processing to unit testing and XML processing, there are robust and well-established APIs available for every function.
The Working of the Java Virtual Machine
Understanding the Java Virtual Machine or JVM will never be explicitly mentioned in a job description when you apply for Java developer jobs, but will almost always be expected. If your aim is to write high capacity or high-performance Java code, the understanding of the inner working of Java is all but necessary. You must learn how all the different parts of the JVM work to gain the deep insight required to be a great developer.
DevOps Tools: An Essential Modern-day Requirement
Almost 60% of all hiring managers are looking for DevOps engineers. Learning at least the basics of DevOps has become a near necessity in today’s day and age. In fact, the least you can learn when it comes to DevOps is continuous integration and continuous deployment (CI and CD), since these functions help firms considerably reduce their reliance on human oversight.
If you are a Java developer in a senior position, learning DevOps becomes all the more essential for you since you might not be directly involved in development, but do have to decide guidelines and practices for coding and create environments in which the other developers carry out their work.
Java developer jobs might be available in a large number, but they also require a high level of competence to succeed. Learning the above skills is sure to better your chances of finding a Java job faster.
