 # Variables
 
 Variables store values. They are the most basic entity used to store data such as text, numbers, etc. in a program.

 ## Variable Data Types
 
 As evident from the above example, variables of Primitive type behave slightly differently from variables of Reference (& Wrapper) type - while Primitive variables <i>store</i> the actual value, Reference variables <i>refer to</i> an 'object' containing the actual value.

+## Rules for naming Variable
+
+ -> All variable names must begin with a letter of the alphabet, an underscore, or ( _ ), or a dollar sign ($).  The convention is to always use a letter of the alphabet.  The dollar sign and the underscore are discouraged.
+
+ -> After the first initial letter, variable names may also contain letters and the digits 0 to 9.  No spaces or special characters are allowed. 
+
+ -> The name can be of any length, but don't get carried away.  Remember that you will have to type this name.
+
+ -> Uppercase characters are distinct from lowercase characters.  Using ALL uppercase letters are primarily used to identify constant variables.  Remember that variable names are case-sensitive.
+
+ -> You cannot use a java keyword (reserved word) for a variable name.
