Lab Objectives
Be able to create complete Java programs with
Simple arithmetic operations
Proper input and output
Be able to use proper test data sets to thoroughly test and debug a program
BMI = (weight in kilograms) / (height in meters)2 or
BMI = ( Weight in Pounds / ( Height in inches)2 x 703
(note: the result BMI is an integer.)
Task #1 BMI (Body Mass Index) Calculation in Metric System
Write a Java program to do:
Ask user to enter weight and height in kilograms and meters (may use real numbers such as 110.5 kg or 1.65 meter) respectively.
Calculate the user’s BMI, and round the result to nearest integer.
Display the weight, height, and BMI (note: output format for weight and height uses 2 digits after decimal point, i.e. 1.65 meter okay, but not 1.650 meter.)
Task #2 BMI (Body Mass Index) Calculation in Metric System
Write a Java program to do:
(1) Ask user to enter weight and height in pounds and inches (may use real numbers such as 185.4 lbs or 65.5 inches) respectively.
(2) Calculate the user’s BMI, and round the result to nearest integer.
(3) Display the weight, height, and BMI (note: output format for weight and height uses 2 digits after decimal points.)
Required Test Cases:
Task #1:
52.5 kg, 1.62m (2) 75 kg, 1.68m (3) your choice
Task #2:
110.5 lbs, 62.5” (2) 180 lbs, 68” (3) your choice
Observation: What happens if weight entered is 0? What happens if height is 0?
Submission
Create a script file with a copy of both programs and all test runs
Submit on blackboard 3 files: the script file, the task1.java file, and task2.java file. Note: file names could be your choice.
Grading Criteria
Readability and program format (proper use of comments, variable names, indentation, etc.) 2 pts
Task #1 Program and testing (4 pts)
Task #2 Program and testing (4 pts)
