java introduction tutorial

This tutorial covers java introduction tutorial in detail. Java is a computer programming language, it enables programmers to write computer instructions using English-based commands, instead of having to write in numeric codes. It’s known as a “high-level” language because it can be read and written easily by human beings.

Like English, Java has a set of rules that determine how the instructions are written. These rules are known as its “syntax”. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute.

We are the going to see in detail about Java Standard Edition platform.

Nowadays Java is required to learn the future enabled courses like the internet of things, big data, testing tools.
