In this lesson we will review arithmetic and unary operators. Arithmetic operators are addition (+), subtraction (-), multiplication (*), division (/) and modulus (%). Unary operators include increment (++), decrement (- -), negation (-) and the not (!) operator.

TERMS:
Operators: Operators are used to perform operations on variables and values.

Expression: Expressions are built using literals (values), variables, operators and method calls.

Condition: A condition is used in a decision process to determine if the evaluation of 2 expressions is true or false.

COACH JOE RULES:
#9: No magic numbers

No hard coded numbers in the code; assign these numbers to a variable or constant.


COACH JOE MISSION:
This Coach Joe video series is an introduction to java programming. Lesson tutorials are broken down into visual descriptions, code syntax and examples. With emphasis on following preferred standard coding rules along with following the concepts of test driven development (TDD) and unit testing. Many lesson topics apply to other languages like C#, Python, Typescript and Kotlin. Here are a list of topics included in this series that will help with your learning and education process:

Class
Constructor
Methods
Properties
Data types (primitive & non-primitive)
String
Integer, long, double, float
Dates
Array
List
HashSet
HashMap
Boxing and Casting
Type conversion
Object or Data structure
Operators (arithmetic, unary, assignment, relational, logical, bitwise and ternary)
If & Else
Switch case
For loop
