Identifiers and Operators

An identifier is a name you give to a variable. To create an identifier, you can use any unicode character you want and it can be as long as you wish, as long as it starts with a letter and is not a keyword. Check out Sun's section on identifiers in its tutorial at http://java.sun.com/docs/books/tutorial/java/nutsandbolts/variableNames.html. An operator performs a function on one, two or three operands, variables to the operator. For more information on operators, Check out Sun's section on it in its tutorial at http://java.sun.com/docs/books/tutorial/java/nutsandbolts/operators.html.
