10 Best Online Courses to learn Java for Beginners in 2023

Without wasting your time, here is a list of the best online courses to learn Java in 2023. The list includes the best Java courses from Udemy and Coursera, two of my favorite online learning platform for technical skills and programming. 


1. Java Programming Masterclass covering  Java 17

With over 208,000 students registered, this is perhaps the most popular Java course on Udemy.
It has over 40K 4.6 reviews, which speaks something about its quality. However, the most essential aspect of this course that I enjoy is that the instructor has regularly updated it to reflect changes in Java 8 and Java 9.

It's a 72-hour course covering everything a Java developer needs to know, including data structures, OOP, Core Java Fundamentals, Java Collections, Multithreading, File IO, Networking, Database, Java 8, Unit Testing, and Java 9 improvements.

This best Java course on Udemy has a lot of social proof because the instructor, Tim Buchalaka, is also a well-known Java instructor on Udemy. Every topic is well taught, and you will learn each subject one program at a time.

You will not only study principles but also free and important tools for Java programming, such as Eclipse and Maven.  In short, one of the most comprehensive Java online courses available is suited for both novices and Java developers returning to the language after a lengthy absence.

3. Java Programming and Software Engineering Fundamentals

This is one of the best Java course and certification on Coursera is designed for novices and will teach you essential programming ideas and how to construct programs to tackle difficult issues.

The specialty includes four courses: Object-Oriented Programming in Java, Data Structures, Advanced Data Structures, and Mastering the Software Engineering Interview. All of the courses in this specialization are free to audit, but you'll have to pay money if you want a certificate, which isn't a bad offer.

By the way, if you find Coursera courses useful, which they are because they are created by reputed companies and universities around the world, I suggest you join Coursera Plus, a subscription plan from Coursera which gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects.

3. The Complete Java Development Bootcamp 

This is a relatively newer course to learn Java but its so amazing that I had to include in this list. While Udemy has thousands of Java courses not every one of them is good. Many of them are there created without thought and any research just to earn quick bucks but this is not one of them

This best Java course for beginners on Udemy is taught in bootcamp style. It's very well structured, lessons are small and concepts are well explained and both audio and visual quality is great. This course is created by Jad Slim, Rayan Slim and Jose Portilla. Having Jose Portilla on Team really helped to make this course beginner friendly given his experience with Udemy's most popular Python Bootcamp course

If you know Java and want to take your Java skills to next level than also this course is good for you. The 27-hour of content is designed to teach you Java in depth. You can join this one course to become an experienced Java developer. It's also full of coding exercise, more than 100 to hone your coding skills.

The course is also very engaging and interactive as there are more than 50 quizzes to revise the key concepts and there are also workbook to practice concepts by writing code. The course also comes with 10 Project or big Coding challenge like creating Tic Tac Toe Game or coding BlackJack which makes learning Java both fun and exciting. 

In short, one of the best and up-to-date online course to learn Java in 2023. Whether you are just starting with Java or coding in Java for years, I highly recommend this course to learn Java better.

4. Java Programming for Complete Beginners [Udemy]

This is one of the newest Java courses on Udemy, thus it's also the most up-to-date. It teaches you how to write in Java using tools like JShell, which was introduced in Java 9. Without a doubt, it's a fantastic tool that makes experimenting with Java a breeze.

The course format is also excellent, with a step-by-step approach to teaching. Having taken some of the instructor's Spring courses in the past, I am familiar with his approach and teaching manner.

The course is also quite thorough, covering everything from Java foundations through Object-Oriented Programming, Java Collections, Generics, Multithreading and Concurrency, Functional Programming Networking, File Handling, and Exception Handling.

If you are studying Java to gain a job, you should feel quite comfortable reading and developing Java programs once you have completed a course. You should also feel secure taking any Java interview once you have completed a course.

In summary, it's currently the greatest and most up-to-date Java training available, and the best part is that it's free. In Udemy, the teacher retains their course for free for a set period to meet their promotional goals, after which it is transformed into a paid course. So sign up now before it turns into a paid course.  Once you've registered for the course, you'll have unlimited access to all of the chapters and accompanying materials for the rest of your life.

5. Object-Oriented Programming in Java Specialization [Coursera]

This Coursera Specialization is for aspiring tech workers who have some programming expertise in at least one other programming language (such as Python, C, JavaScript, and so on) and want to learn how to handle more complicated issues with Java using object-oriented design.

In addition to studying Java, you'll get hands-on experience with two Java development environments (BlueJ and Eclipse) and learn how to program with graphical user interfaces and create applications that can handle enormous volumes of data.

6. Java In-Depth: Become a Complete Java Engineer! 

This is another fantastic Udemy Java course that you can use to master Java from the ground up. It was a terrific course, and I had a lot of fun with the topic "In-Depth."

The instructor is highly knowledgeable about Java, and his explanations are excellent, making learning more enjoyable.

This is a highly deep and complete course, similar to a prior Java course, and it covers the bulk of Java subjects a beginner would want to learn, such as variables, methods, classes, collections, data structures, threads, networking, and so on.

duration: 67 hours
instructor: Dheeru Mundluru

On the negative side, the course is mostly a slide-based course with a few code examples thrown in for good measure. A few additional code samples, particularly using modern technologies such as JShell, would be quite beneficial.
