Variables are used to store data that can change. There are two main categories of variables, ''reference variables'' and ''primitive variables''. Reference variables are place holders for objects (More on objects in Lesson 4, [[Java Objects and Classes]].) Primitive variables are given a value of a primitive, a basic value. Variables are all given a type when they are declared, such as "int" or " | Variables are used to store data into your computer memory, that can change.
