PART A

Write a complete Java program, including a good comment (see sample program below) at the top, to do the following:

• Take any version of a simple program that was done in class (for example, see below)
• Type it up in an IDE of your choice, save it, run it and view the output.
• Be sure to include one or more comments giving your name, class, section and the purpose of the program.
  • You are required to include this type of comment on every program you write for the course or else it will not be accepted.
• If you change the code of

System.out.println((10.5 + 2 * 3) / (45 - 3.5));

to

System.out.println(((10.5 + 2) * 3) / (45 - 3.5));

What is the output? Explain the difference! Note the change in parentheses!

• Print a copy of the program and a copy of the output from the program.

SAMPLE PROGRAM:

//Ira Rudowsky CISC1115 Lab #1

//This program allows you to compute a mathematical

//expression and see the result on the screen

public class ComputeExpression { 

 public static void main(String[] args) { 

 System.out.print("(10.5 + 2 * 3) / (45  3.5) = ");

 System.out.println((10.5 + 2 * 3) / (45 - 3.5));

 }

}

PART B

• Repeat part A, but this time write your own computation expression
• Type it up. Save it. Run it. View the output
• Print a copy of the program and a copy of the output from the program.

Hand in all the programs, output and explanation of the different outputs in Part A.
