About 17 percent of children and teenagers (ages 2 to 19) are considered obese. The following table shows the percentile range for each weight status: PercentileДЄccording to the National Institutes of Health, more than two in three adults are considered overweight and one in three are considered obese. This means that they have more body fat than 95 percent of children in the same age and gender category. For example, a child would be considered obese if they had a BMI that landed at or above the 95th percentile. Each percentile expresses a childвЂ™s BMI relative to other children of the same age and gender. Girls usually acquire a higher amount of body fat and develop it earlier than boys.ДЇor children and teens, the CDC uses age growth charts to show BMI as a percentile ranking. ItвЂ™s also different in young boys and girls. While the same formula is used to determine BMI for all age groups, the implications for children and adolescents can vary depending on age and gender. So ideally you need so sort of validation or error handling in your program.perhaps a validation method that requests new input if an error is thrown? Remember, it's very easy to assume that users will never input silly things like words where numbers are meant to go but trust me.they will.BMI is interpreted differently for people under age 20. In your example if the user inputs a String rather than an integer that will throw an error causing the program to terminate.

Perhaps multi-line comments would be more useful to give a general explanation to what certain sections of your code do?ДЄlso Scanner has a tendency to throw errors if the value you are assigning isn't what it's expecting. In regards to commenting, yes some comments are somewhat pointless if what you're doing is pretty self explanatory. I for example would would have a getInput methods to get the values for the user, a convertMeasurements method for converting the users input and finally a displayResult method. Sectioning pieces off makes it easier to understand, aids maintainability and debugging as well as makes parts of your code more re-usable. Think of using methods as the a similar concept to paragraphing your writing.

Although you may not have learnt how to make other methods yet, it is a simple concept to learn and is easily found on numerous YouTube tutorials. Reading from the previous answer given by krasevich I too recommend you become familiar with using multiple methods rather than putting everything in the main method. The many comments tell the reader that you are a beginner, but don't worry, in a few weeks you can remove them and still understand the program equally well. input.close() ДЄltogether, a very nice piece of work. Each line should be terminated properly, which you do with println. When printing something, you usually print it in lines.

double bmi = weightInKilos / (heightInMeters * heightInMeters) 0254) Дouble bmi = weightInKilos / Math.pow(heightInMeters, 2.0)

('Enter weight in pounds: ') Дouble weightInKilos = weight * 0.453592 Дouble heightInMeters = (((feet * 12) + inches) *. Write a java code to let the user enter weight, feet, and inches and interpret the users BMI. It can be calculated by taking your weight in kilograms and dividing it by the square of your height in meters. Body Mass Index (BMI) is a measure of health based on height and weight.
