IT205 Intro to Object Oriented Programming

Date: October 24, 2025
Pledge: This program is entirely written by me (Carter Hendrick) without help from anyone except starter program
Starter program for Module2 program assignment.
You may modify this program for your submission
notes:
syntax of a static method (method definition)
accessModifier static returntype methodName(formal parameter list){body}
syntax of formal paramter list: datatype par1,datatype para2,….
method call is always methodName(arguments)
syntax for arguments is var1, var2,…
important: cannot have a method definition within other method definitions
