This article will explore some of the best tools and resources available for people who want to learn Java online. Java is one of the most widely used programming languages today. It is used for almost everything – game design, data analysis, enterprise systems, web applications, and more.

If you’re considering a career as a programmer, there is a very good chance you’ll need to be familiar with the language. For a hobbyist who wants to learn Java online, there are plenty of great resources. Online classes are especially useful for beginners, offering guided practice for learning Java online.

Note: The courses described below are presented in no particular order.

3 Courses and Resources to Learn Java Online

1. Introduction to Programming with Java – edX

Massive Open Online Courses (MOOCs) are quickly becoming a great alternative to expensive university classes in many subject areas. To effectively learn Java online, it’s unnecessary to be in the same room as your instructor and classmates. As long as you’re getting quality feedback and being challenged, your coding skill will improve.

edX has a number of Java courses for all levels. For a beginner, their Introduction to Java Programming is a great self-paced class that typically lasts five weeks, taking 7-10 hours per week. The videos for the class are administered from Universidad Carlos III de Madrid, in Spain. Keep in mind that the courses are still in English, so there’s no need to worry if you don’t speak Spanish.

The course starts with some basic lessons on algorithms and various Java commands. Participants will develop some simple programs using loops and conditional statements. From there, it goes into topics such as recursion and Object-Oriented Programming (OOP). The course also delves into interpreting the application program interface (API) of some of the more common Java classes. Finally, the course culminates with a project in which you, the student, build your own simple program.

edX has been at the forefront of the MOOC movement, and their programming classes tend to be particularly popular. If you’re a more experienced programmer, you can also find Java courses there aimed at intermediate or advanced coders. Their platform will provide you all the necessary details to help you decide whether or not you should subscribe to this course.

2. Core Java Programming – LearnVern

LearnVern has some very useful Java tutorials. They contain pertinent info for all kinds of Java projects, from the basic syntax of the language to more advanced concepts like (OOP) and Multithreading. Like the previous course, these tutorials are also self-paced. This makes them a great option for anyone with a busy or unusual schedule.

In addition to the basic commands and syntax of the language, this course also covers more advanced topics like serialization, collection frameworks and generics, and exception handling. There are periodic tests and quizzes given throughout the tutorial to make sure that you’re retaining all the information. This is important, as the tutorials are densely packed with information, and most people will inevitably need re-watch various sections at some point.

One aspect that is overlooked in many Java guides is its role in database programming. Thankfully, this course doesn’t make that omission. There is a thorough section on Java Database Connectivity (JDBC), which is a Java API that is used to make queries with databases. If you’ve never worked with a relational database before, their architecture will be explained in a way that’s easy to understand.

Although this course is rather expansive in the amount of information it covers, there is a gradual learning curve that makes it accessible to most people. The only prerequisites are basic computer knowledge and solid analytical skills. In other words, anyone who knows how to use a computer and is willing to put in the time and effort can get started learning Java online. The website has a comprehensive Java curriculum, which you should be aware of if you want to improve your Java skills.

3. The Java Tutorials – Oracle

If you want to get your Java training from a primary source, Oracle itself has a quality set of tutorials that anyone can use to learn Java online. For those not familiar with Java’s past, it was created by Sun Microsystems, a company eventually acquired by Oracle.

One key difference between Oracle’s tutorials and the two previously mentioned are that Oracle’s guides are written in the form of documentation. Whereas the other two options include many instructional videos in addition to documentation, Oracle’s guides are comprised solely of text. Whether this is good or bad is ultimately a matter of preference. There are different types of learners, and everyone should choose the type of method that works best for them.

One aspect of Oracle’s tutorials that isn’t different is the way in which they begin. In order to program in any language, it’s important to understand the syntax of the language. Also important is the ability to understand and implement basic algorithms. Knowledge of OOP is once again covered. The guide will teach you the difference between an object, class, inheritance, interface, and a package.

When it comes to programming, practice makes perfect. Like any good programming tutorial, Oracle’s Java guides include exercises at the end. These exercises have you creating and using packages, an essential skill for anyone learning Java online. By navigating through their platform, you will figure out whether this course is a good fit or not.

In summary, there are three great options here for getting anyone started learning Java online. The first two are delivered by a combination of media in a more traditional academic format. The last one is written in the form of documentation, not unlike the documentation programmers are often required to read. The best advice I can give for anyone aspiring to learn Java online is to just do it. Check out one of these great learning platforms, digest as much information as you can, and get started.
