The following problem shows up in a number of Java texts, including Savitch's textbook: 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: WBMR = 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: MBMR = 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. NOTE: This is an application of a selection statement! Input Data: Use a named constant for the number of calories in a “typical chocolate bar.” Use Scanner methods to enter the following input data at the keyboard: weight height age sex (select from one of the following strings): man woman NOTE1: your program should be able to process any of the above strings, regardless of how it's entered. The following are just some examples: Man, mAN, woMAN, Woman, WOmaN, ... NOTE2: If any other string is entered, the program should display an appropriate message (such as, "this program processes data for a man or a woman only.") and stop. Processing: Set up the equations to calculate the basal metabolic rate: WBMR (basal metabolic rate for a woman) MBMR (basal metabolic rate for a man) Calculate number of chocolate bars consumed by a man to maintain his weight Calculate number of chocolate bars consumed by a woman to maintain her weight Use one method that takes in all necessary input (including sex) to calculate the WBMR and MBMR and returns the value. Output Data: Using appropriate messages, provide: weight height age sex number of chocolate bars consumed

NOTE: This is an application of a selection statement!
Input Data:
- Use a named constant for the number of calories in a “typical chocolate bar.”
- Use Scanner methods to enter the following input data at the keyboard:
- weight
- height
- age
- sex (select from one of the following strings):
- man
- woman
NOTE1: your program should be able to process any of the above strings, regardless of how it's entered. The following are just some examples: Man, mAN, woMAN, Woman, WOmaN, ...
NOTE2: If any other string is entered, the program should display an appropriate message (such as, "this program processes data for a man or a woman only.") and stop.
Processing:
- Set up the equations to calculate the basal metabolic rate:
WBMR (basal metabolic rate for a woman)
MBMR (basal metabolic rate for a man)
- Calculate number of chocolate bars consumed by a man to maintain his weight
- Calculate number of chocolate bars consumed by a woman to maintain her weight
- Use one method that takes in all necessary input (including sex) to calculate the WBMR and MBMR and returns the value.
Output Data:
Using appropriate messages, provide:
- weight
- height
- age
- sex
- number of chocolate bars consumed
