Do you want to know the best online course for Java developers?

I’ve already discussed the top Java websites, tutorials, and books for beginners and the greatest Java books and free Java courses. Today, we’ll look at some top online tutorials for learning Java development. These online Java courses have been hand-picked from the best resources, including Udemy.

There is a healthy amount of competition among Java developers because it is one of the most popular programming languages in the world. If you want to get ahead of the competition and start carving out a name for yourself as a Java developer, you’ll need the online top Java classes and the right training. So, here is a summary of my review.

What is Java?

High-level object-oriented programming language Java has one unique feature that sets it apart: platform independence. In other words, it may be developed once and operate on every operating system, including Windows, MacOS, and Android.

It compiles to Java Bytecode, a step between pure written Java & machine code, instead of directly to machine code. A Java Virtual Machine (JVM) for a particular operating system must be installed to run the Java Bytecode. The Java Virtual Machine (JVM) translates the Java Bytecode into machine code that the operating system may execute.

According to the TIOBE index, Java has grown to be the third most popular language because of its adaptability. Java is also easier to learn for beginners than languages like C & C++ due to its simplicity. According to Glassdoor, the average yearly salary for a Java developer in the US is $110,713. Consequently, there is a high need for Java developers!

The sections on Streams/Lambdas API, Regex, Date/Time, Optionals, SQL/Database/JDBC that even seasoned Java developers might not understand as well as they should be skipped over by individuals who already have a fundamental understanding of Java. Regarding these APIs, several of my sections are as long as or longer than several stand-alone courses that cover just one of these topics and cost about the same. Watch the preview films I made for each section to see how in-depth I get into each subject.
