JAVA-Introduction to JAVA.

Introduction to JAVA

Java is a programming language designed to build secure, powerful applications that run across multiple operating systems, including Linux, Mac OS X, and Windows. The Java language is known to be flexible, scalable, and maintainable.

We will begin with the fundamentals of Java programming: data types, arithmetic, and operators. We’ll learn a few concepts that you can apply to the programs you create. By the end of the course, you’ll be familiar with the basic building blocks of a Java program.

Data Type I: int

Creating more useful Java programs will likely require you to work with several additional types of data. Let's explore a few of them.

The first data type we will use is int.

1. int is short for integer, which are all positive and negative numbers, including zero. This number could represent the number of visits a website has received or the number of programming languages you know.
2. The int data type only allows values between -2,147,483,648 and 2,147,483,647.
