Question

3.44444444 The following are requirements of ALL programs that you write from this point on!

You must write instructions to the screen to tell the user exactly what you want him/her to do. Your instructions must be very clear and descriptive, and should not contain any spelling or grammar errors.

You MUST choose variable names that describe the contents of the variable. Unless I specifically tell you to do so, single character variable names will not be acceptable unless you are using them to hold temporary data.

In addition to putting your name at the top of the program, you should also add a comment, 1-2 lines long, to briefly describe what the program does.

You MUST follow proper indention techniques in your code as discussed in class, and seen in the examples in your book. If you aren't sure you have the indention correct, you can use the correct indention option from the source menu in Eclipse.

Your source code must be NEAT and easy to read. Declare all of your variables at the beginning of the program. Add blank lines between sections of code to space out your program more and make the sections easier to see.

You MUST add comments all throughout your code to explain what your code is trying to do.

Pay close attention to the directions!! Make absolutely certain that you are doing exactly what the assignment asks you to do. If you don't understand the problem, make sure to ask your instructor or an assistant.

This is the last time you will be reminded of these requirements-- you must remember to start doing them in all of your programs from now on!

Part 3

Create a new Java class inside your project folder.
The name of the class should be: MeetingTimes

Write a program that determines the best possible meeting time for four people. The possibilities for meeting times are 8:00-12:00, 12:00-18:00 or 18:00-23:00.

You should begin by asking the first user to choose a meeting time. The user should enter the number 1 for the 8:00-12:00 meeting time, the number 2 for the 12:00-18:00 meeting time, or the number 3 for the 18:00-23:00 meeting time.

Make sure that you display the three options on the screen for the user.

The program will then proceed to do the same thing three more times (for the other three people).

At the conclusion, the program should display on the screen the best possible meeting time. For our purposes, this will be the time block chosen by a majority of the people. In the event that there is a tie for time blocks, choose the earliest one.

The following is an example of what your MIGHT see on the screen when your program runs. The exact output depends on what values that the user types in while the program runs. The user's values are shown below in italics:

Meeting Times:
1) 8:00-12:00 2) 12:00-18:00 3) 18:00-23:00

Choose option 1, 2, or 3.

Enter the best time available for person 1: 2
Enter the best time available for person 2: 1
Enter the best time available for person 3: 3
Enter the best time available for person 4: 2

The best meeting time available is:
12:00 - 18:00

Here is another example run of the program:

Meeting Times:
1) 8:00-12:00 2) 12:00-18:00 3) 18:00-23:00

Choose option 1, 2, or 3.

Enter the best time available for person 1: 3
Enter the best time available for person 2: 1
Enter the best time available for person 3: 1
Enter the best time available for person 4: 3

The best meeting time available is:
8:00 - 12:00

Hint:

Use three separate counter variables to keep track of the total number of people who entered option 1, total number for option 2, and total for option 3. As the user enters each option, use IF statements to decide which option was chosen, and then update the appropriate counter accordingly
