Introduction to Number Types

In this lesson, we will explore the fundamental concepts of number types in Java. Understanding how different data types manage and preserve memory is crucial for efficient programming. Let's dive into the world of number types!

The number types in Java are:byte, short, int, long, float, double

The main ones you will be working with are integers and doubles.

To fully understand numbering systems, you will also need to have a basic understanding of the binary system. It is not required, but highly useful.

int integer = 2;

double a = 2; //yes, this works - is 2.0

byte b = 1;
