Learn Java

Java is a great first programming language to learn. It was released in 1995, so there are tons of books and online resources. Java is derived from C, similar to C++ and C#; if you know one, it's easier to learn another. Lastly, it's an object-oriented language; the concepts learned in Java are transferable to other popular languages like JavaScript and Python.

What is Java?

Java is an object-oriented programming language first released by Sun Microsystems in 1995. Java has become one of the most popular languages in academia and the tech industry. In fact, Java is still among the most in-demand languages in the job market today. Java was one of the first platform-agnostic programming languages. While other languages (like C++, for example) are dependent on the operating system, the Java compiler creates byte code that can run on all operating systems. In other words, Java is portable and ideal for Windows, Mac OS, Linux, and mobile devices.
