Repeat Practice Program of Chapter 3, but use JOptionPane windows for input and output. O ffer the user Yes and N o buttons to end execution instead of asking for character input of Q or q. JOptionPane is described in the graphics supplements

use a loop so the user can convert other temperatures. If the user enters a letter other than C or F—in either uppercase or lowercase—after a temperature, print an error message and ask the user to reenter a valid selection. Do not ask the user to reenter the numeric portion of the temperature again, however. After each conversion, ask the user to type Q or q to quit or to press any other key to repeat the loop and perform another conversion.

Repeat the calorie-counting program described in Programming Project This time ask the user to input the string ″M″ if theuser is a man and ″W″ if the user is a woman. Use only the maleformula to calculate calories if ″M″ is entered and use only thefemale formula to calculate calories if ″W″ is entered. O utput the number of chocolate bars to consume as before.

The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate, or BMR.

The calories needed for a woman to maintain her weight is:

BMR = 655 + (4.3 × weight in pounds) + (4.7 × height in inches) − (4.7× age in years)

The calories needed for a man to maintain his weight is:

BMR = 66 + (6.3 × weight in pounds) + (12.9 × height in inches) − (6.8 × age in years)

A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input his or her weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age.
