A variable in java is something that holds a value and has a name attached to it. This value can change and hence its named a variable.
There are two types of variables in Java:
• Primitives - A primitive variable can be one of eight types: char, boolean, byte, short, int, long, double, or float. Once a primitive has been declared, its primitive type can never change, although in most cases its value can change.
• Reference variables - A reference variable is used to refer to (or access) an object. A reference variable is declared to be of a specific type and that type can never be changed.
