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
1. Create a folder on your desktop Exercise-3
2. Launch Java EE- Eclipse
Note: You will need to use the Java Perspective Workbench for this exercise
3. Setup your Eclipse Workspace to point to the Exercise-3
a. Select File-> Switch Workspace
b. Browse and select your Exercie-3 folder as your Workspace.
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
NOTE: Right click on the subfolder and select Send to “Compress Folder”. The file will have a file extension of .zip.
