Body Mass Index (BMI) Calculator in Java

(Body Mass Index Calculator) We introduced the body mass index (BMI) calculator in
Exercise 1.10. The formulas for calculating BMI are
or
Create a BMI calculator that reads the user’s weight in pounds and height in inches (or, if you prefer, the user’s weight in kilograms and height in meters), then calculates and displays the user’s
body mass index. Also, display the following information from the Department of Health and
Human Services/National Institutes of Health so the user can evaluate his/her BMI:
