What is Java?
Java is an OOP (object-oriented programming) language which came to usage in 1995. Java was developed at sun microsystems which later acquired by Oracle. Programs or applications developed in Java will execute in a JVM (Java virtual machine) by which we can run the same program on multiple platforms and systems/devices etc. If we want to run Java program on the browser we need to use Java applets which are embedded as a plugin which is not suggested. So Java is mostly used for standalone applications or back-end development. Java was designed by James Gosling and its major implementation was OpenJDK.
