Java is an incredibly popular programming language that was invented by James Gosling in the 1990’s. Today, the internet is saturated with Java-run programming and many of the applications that we use each day are only possible due to Java programming.  As a result, it is crucial that those wanting to work in technology and web development understand how to use and utilize Java. 

Unlike JavaScript, Java code must be compiled and each language requires a different plug-in. It can create applications that run in a virtual machine or browser and is one of the most used object-oriented programming languages. 

New coding students are advised to learn Java, as well as JavaScript, early on so that they are more employable and have more lucrative job opportunities! To learn Java, you can take a number of online classes. Suitable for all levels, I have spent the time researching the best online Java coding tutorials out there.
