Overview about Java
Java is an object-oriented computer language that can be used in many situations. It was created by Sun Microsystems in 1991 and later bought by Oracle Corporation. It's meant to be easy to use, safe, and work on any device. This makes it perfect for making a lot of different kinds of apps, from mobile ones to business systems. "Write Once, Run Anywhere" in Java means that once code is built, it can run on any device that supports Java without having to be recompiled.
