 * Description: These are the basic required components of a simple Java program
 * The program prints "Skeleton Code!" to the screen as a string literal, declares 
 *  and initializes three variables, manipulates the data values within those 
 *  variables by using arithmetic operators to change the values held by the 
 *    variables, and prints the contents of the variables to the terminal.
 *
