Project 3 Instructions
1. Due Date & Time: 09-26-2020 at 11:59 PM

WHAT TO SUBMIT

Submit 1 zip file containing 4 files below to iLearn by the deadline. [30 points]

• ● 3 JAVA Files: TableBmiPro.java, MyOwnIdea.java. DiceRoll.java [24 points]

• ● 1 File: Make a document that shows the screen captures of execution of your programs and learning

  points in Word or PDF. Please make sure you capture at least 2 executions for 1 program, so 6 screen captures and one paragraph learning reflection for each [6 points]

  GUIDELINES FOR ALL PROJECTS:

1. Each assignment includes a code portion and a non-code portion. Please submit both 2 portions.

   1. Code portion: Your source code files, only the files which you create and edit.

   2. Non-code portion: Your assignment report, only 1 Word or PDF file.

2. Please submit all required files separately, un-zipped, via iLearn Assignments Submission

3. Always read through the entire assignment before starting and submitting any of it. Missing files or

   missing requirements will result in deducted points

❐Part 1: BMI History Pro [8 points]

1. Prompt our user to enter his/her height in feet and inches (two integers).

2. Prompt our user to enter his/her lowest weight in pounds (an integer).

3. Prompt our user to enter his/her heaviest weight in pounds (an integer).

4. Print a table of Body Mass Index (BMI) for the height entered:

a) Weights range from the low weight to the high weight, at increments of 5 pounds.
▪ This means to get more than 1 line low weight and high weight should have more than 5 pounds

  

of difference

CSC 210 PROJECT 3 FALL 2020

▪ To get additional decimals behind decimal point, you may want to cast one of the variables into a float or a double

b) Each row of the table lists

• ▪ The value of WEIGHT (an integer), followed by spaces, then

• ▪ The value of BMI to four decimal places (a float), followed by spaces, then

• ▪ The CONDITION whether overweight (BMI > 25), or not overweight (BMI <= 25).

5. Document our code carefully. Our program output must be identical to the sample output (except author name).

OUTPUT OF SAMPLE RUN FOR PART 1

❐Part 2: DiceRoll [8 points]

1. Make a dice and rolls it 10000 times. Each time you count how many times each face [1-6] appears and check if the random number actually works. Please make your program to roll once and then make it roll 10 times for easier debugging. And then you can increase the number of roll to be 10000. You can use this NUMBER_OF_ROLL as a constant and changes when needed. Or you can make it a user input. However, you should not use this number of roll hard-coded!!!

2. Comment your code carefully assuming you are teaching your friend to learn from your comments.

FALL 2020

3. Include screenshots and notes in your report.

OUTPUT OF SAMPLE RUNS FOR PART 2

[When the NUMBER_OF_ROLL is 100] Occurrence of each face is
11, 20, 22, 13, 19, 15: 100.0

Therefore the probability of each face is 0.11, 0.2, 0.22, 0.13, 0.19, 0.15

[When the NUMBER_OF_ROLL is 10000] Occurrence of each face is
1667, 1700, 1665, 1683, 1616, 1669: 10000.0

Therefore the probability of each face is 0.1667, 0.17, 0.1665, 0.1683, 0.1616, 0.1669

❐Part 3: Your own idea [8 points]

It can be similar to part 1 or 2.

Please use what you learned from Loops.

a. In Assignment 1, Part 3 and in Assignment 2, Part 2: Your own idea, you created your own idea of a program. For this assignment, you must improve upon your first program by adding what you learned from Loops

b. Must include Loops, using either “for”, or “while”
c. And, must use the loop to output more than 1 line of result
d. Must provide an explanation to the user of your idea “This program will help you... ” (2 points)

FILE NAME REQUIREMENTS MyOwnIdea.Java

❐Part 4: Comment your code

CSC 210

PROJECT 3

FALL 2020

Every Java file you write in this assignment will require you to include descriptive comments. In this assignment, you are tasked with writing a descriptive
1. Headers
2. Comments

You can write comments in two ways:
• Single-line comments using the // notation.
• Multi-line comments using the /* and */ notation.

a. Include a proper header at the top of every Java file. Figure 1

Header Format

/*
* Assignment <assignment number> * Description: <program description> * Name: <your name>
* ID: <your SFSU ID number>
* Class: CSC 210-<section number>
* Semester: <current semester>
*/

Replace each tag (such as <assignment number>) with the appropriate text.

You should adhere to this format as closely as possible. You do not need to include the <> symbols in your header fields.

b. Only if you work with a Study Buddy, include your Buddy’s name in your header at the top of every

Java file. Figure 1
