Java is a programming language that has stood the test of time. Sun Microsystems was first released in 1995 and is still in regular usage to this day. Knowing how to program in Java could open many doors for you and potentially lead to a great job.

Java has the advantages of being object-oriented, meaning you’ll be able to reuse code and create modular-based programs. It’s also platform-independent, so it’s not limited to a specific operating system. This makes Java an excellent fit for web-based programming. 

But who even uses Java?

Programs such as Minecraft, the Wikipedia search engine, and even the Mars Rover use Java. There are several online courses you can take to learn Java and up your programming game.

Why Learn Java

Java is a prevalent programming language, and having a solid understanding of it will likely make you more employable or provide advancement in your current career.
