LAB EXERCISE 3: BMI Calculator
Goal: In this exercise, you will learn how to:
1. Insert comments (documentation)
2 Declare variables and assign data types
3. Assign data to the variables
4. Compute for a value and display results on the screen

Variables and Data Types

Program Specifications: Create a Java program that will calculate the Body Mass Index (BMI) of a patient. Store and assign the data - patient name, age, height (inches) and weight (pounds) in variables. Display the patient’s BMI results on the screen. The formula of the BMI in Standard measurements is:

BMI = weight / (height * height) *703

A. Pre-requisites:
1. Create a folder on your desktop Exercise-3

2. Launch Eclipse

3. Setup your Eclipse Workspace to point to the Exercise-3 folder
a. Select File-> Switch Workspace
b. Browse and select your Exercie-3 folder as your Workspace.


B. Requirements:

1. Create a Java Project and name it as BMICalculator

2. Create a Class

a. Name the Class as BMICalculator

b. Choose the method stub to insert into the class

3. Add comments (documentation) – Program Description, Author and Date

4. Declare the variables and assign the data types

a. patientName - string

b. age- integer

c. height – double

d. weight – double

e. BMI - double

5. Assign and initialize the values to the variables

6. Calculate the BMI

7. Display the output on the Eclipse Console

Below is sample of the code:

C. Test Application

1. Save your code

2. Compile and run your Java program.

3. Verify there is no syntax, logical or run-time errors.

4. Use the following set of test data to determine if the application is calculating properly:

Patient Name Age Height Weight BMI
Joe Doe 30 68 180 27.37
Jane Jones 35 64 125 21.45

D. Submit your exercise in the Canvas Lab Exercise #3 Drop Box.

1. Submit the screen shot of the Eclipse Workbench window showing the Console output screen (see step B7).
NOTE: You can use Paint (save as JPG) or Word to paste the screenshot.

2. Zip up and submit the compressed BMICalculator subfolder that is in the Exercise-03 folder.
NOTE: Right click on the subfolder and select Send to “Compress Folder”. The file will have a file extension of .zip.
