10 Steps to Become an Outstanding Java Developer

It’s already 5 years since Java 8 was released, so you literally have no excuse left. If you need more resources, you can also check out my earlier articles about the best design patterns books and courses to learn Object-Oriented Design patterns in depth. These are the building blocks of any program, and a good knowledge of Algorithms and Data Structure is vital for your next job or doing well in your current situation. If you are interested, you can find a more exhaustive list of separate blog pots, which I have listed in the further learning section.

  • A code editor is a text editor program designed specifically for editing the code of a computer or web program.
  • CodeGym is an online Java programming course consisting of 80% practice and 20% of the essential Java theory.
  • The beauty of this platform is that it provides source code for each application, so you can use this code even if you are not using this platform anymore.
  • Soft skills help people succeed at work and include communication, problem-solving, and teamwork skills.
  • A Back End Developer builds the server-side of a web application and integrates front end development components.

If you haven’t become a Google search expert, learn how, especially using advanced search techniques. In Java, exception means an event that interrupts the normal flow of events in a program. Exception handling is a method to handle runtime errors such as RemoteException, IOExcpetion, SQLException, etc. We will add your Great Learning Academy courses to your dashboard, and you can switch between your Digital Campus batches and GL Academy from the dashboard.

  • A Java developer is a programmer who specializes in developing applications using the Java programming language.
  • Indicates the Dependency Inversion Principle that says that a java developer should not make the higher-level modules of java coding lower-level modules.

You will need to plan, design, test, deploy, and collect user feedback on the update to build efficiently. If you work in a large business or busy industry, you may need to manage multiple updates simultaneously. Once you’ve written code, you will need to test it with code review tools to identify potential issues. Your employer may expect you to perform a range of rests on your code, including functionality testing, static code testing, unit testing, and single-user performance testing. Pass-around testing is a way development teams ask for feedback by emailing their colleagues their code before deployment. You can see an example of pass-around testing in the image below. New developers also confuse Java developers with software engineers, though these professions are different, too.

Back End Development

They should also be proficient in object-oriented programming, and they should have experience developing web applications and mobile apps. The work will depend on the level of experience (junior, mid-level, senior). In order to be a great Java developer you must first learn the fundamentals of Java. This course introduces the fundamental concepts and practices of Java programming. These include basic Object-oriented Programming concepts such as classes, encapsulation and inheritance, as well as core Java concepts such as collections, exceptions and commonly used Java types. You will have access to this Nanodegree program for as long as your subscription remains active.

  • As many Java developers liaise with IT vendors, you will need good verbal and written communication skills.
  • These programs often feature programming and software development studies.
  • Regular coding practice will make you feel more and more confident.
  • Junior Java developers must be fluent in Java, as well as JavaScript, HTML, and CSS.
  • This concept helps java developers to share the required data that helps in software development.

For developing a mobile app, this platform offers Server Driven UI. After completing the application with this platform, you can publish it on app stores. It is immediately available online; you can check all the application endpoints, test them in practice, access the database, etc. Java developers use this java edition to support small processing devices such as ATMs and SIM cards. Every good Java developer is well-versed in Java SE, and while mastery won’t happen overnight, you should start familiarizing yourself now with its features and terminology.

  • Alright, now let’s get to the important part of how to become a Java developer.

Alternatively, software engineers have a broader skillset to work on different programming languages and projects. As Java developers and software developers have similar roles and skills, many professionals transition between the two roles for variety, a new challenge, or to learn new skills. The software development degree at WGU has two major tracks and students must decide whether they want to focus on Java or C#.
