ABOUT THIS PROJECT
You will be creating simple Java programs. By the end of this assignment, you should understand how to create simple Java programs
❐Part 1: BODY MASS INDEX (BMI) Calculator[9 points]
INSTRUCTIONS Body mass index (BMI) is an estimate of whether a person is overweight. (See for example http://www.halls.md/bodymass-index/bmi.htm .) BMI is defined as 703 * (weight in pounds) / (height in inches)2 . A BMI of 25 is considered borderline overweight. Write a Java program that performs these actions: – Prompt the user to enter height in feet and inches (both integers) – Read the height in two separate prompts. For example if someone is 6 feet 7 inches, then 1. Ask the user to enter their feet part of their height as an integer, first, so : 6 2. Then, ask the user to enter their inches part of their height as an integer, second, so for example: 7 – Prompt the user to enter their weight in pounds (a double) – Calculate the BMI of the user (a double) – Display the BMI NOTE : Please do not use “Integer” class, use “int” FILE NAME REQUIREMENTS BMI.Java SUBMISSION INSTRUCTIONS 1. Submit the 1 BMI.Java file directly on iLearn 2. Take a screenshot of the output of your program and paste it here CSC Note: BMI and weight outputs are rounded to 2 decimal points (.2f) Example
TIPS FOR PART 2 AND PART 3:
1. Save your user’s input in a variable in order to use it in the next printout When you use the Scanner object, don’t forget to save it in a variable like this To save an integer/a number: int myInt = myScanObj.nextInt(); //save user’s number input into an integer primitive variable named myInt To save a string: or String myString = myScanObj.nextLine();/save user’s string input into a String reference variable named myString. And yes, that is a “String” data type, with a capital “S” Why do you want to do this? So that you can print out what the user had entered.
For example: System.out.println(“You entered this” + myInt); or System.out.println(“You entered this” + myString); 2. If you will not be using the user’s input for an output later on, then you don’t need to scan it at all. “scan” means this myScanObj.nextInt(); or myScanObj.nextLine(); 3. The KnockKnock joke is a very simplistic program It is a very simplistic program, so if the user answers anything at all, it will still proceed as if the user entered a correct answer. Meaning you could expect a conversation like this: Knock Knock? ←-your program’s output
XXXBLBBLABs;isdfa98f0s <—- user input, no need to save or scan this Annie <– ignores user input, and goes on with your program output joke XXX…!!ososd9 ← user’s input, no need to save or scan this XXX…!!ososd9 thing you can do I can do better <— you take this last user’s input and add to your response output ” you can do I can do better”
❐Part 2: Knock Knock Joke [8 points] Knock Knock Joke: In the future assignment, you can make a more fun knock knock joke program. For now, it would work for only 1 joke and 1 exact response you may like the best. 😊 Ideally, users are expected to enter the proper response as shown in the green font. And your program responses with 1 joke.
SUCCESSFUL RUN REQUIREMENTS 1. Running the program should output a statement like the above FILE NAME REQUIREMENTS KnockKnock.Java
SUBMISSION INSTRUCTIONS 1. Submit the 1 KnockKnock.Java file directly on iLearn 2. Take a screenshot of your Knock Knock Joke and paste it here. It can be any Knock Knock joke that takes in a user input and outputs a response C S C 2 1 0 . 0 3 A S SIG N M E N T 1 F A L L 2 0 2 0
❐Part 3: Your own idea [11 points] It can be similar to part 1 or 2. Please use what you learned from problem 1 and 2 and write a simple code to make it work. a. It must provide a welcome printout “Welcome to my program called: … “ (2 points) b. Must include prompting reading user input ex. “Please enter this value… “ (2 points) c. And, must use this input for the next step printout. It can be completely funny or serious, or maybe a project you have been thinking on. (2 points)
d. Must provide an explanation of your idea, and what it is trying to do as I showed in 1 and 2. ex. “This program is to calculate blablabla…” (2 points) FILE NAME REQUIREMENTS .Java SUBMISSION INSTRUCTIONS 1. Submit the 1 .Java file directly on iLearn 2. Take a screenshot of the output of your program and paste it here
Explanation: This program is a math mini-game. The pseudocode is as follows: ● ask user for an integer (e.g., 5), ● ask user for the squared value of the integer provided in part 1 (e.g., 25), ● evaluate the answer, ● print a message to tell the user if that was correct. Note: the program does not perform any checks on the input and will crash if an integer is not provided in either parts. Example 1: If the user provides a correct answer to their question Example 2: If the user provides an incorrect answer to their question
❐Part 4: Comment your code [2 points] 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 * Description: * Name: * ID: * Class: CSC 210-
