Question

Create in java an interactive GUI application program that will prompt the user to use one of three calculators, label project name MEDCALC. You can use any color you want for your background other than grey. Be sure to label main java box with “MEDCALC” and include text of “For use only by students”

On all three calculators create an alert and signature area for each user. The alert should be something like “All calculations must be confirmed by user before use.” The user will need to sign acknowledging the alert before they are allowed to move on to use the calculator; at this point your program should also write to a file on the user’s local computer, capturing data of date and name signed (this can be a text file or excel file). Again, User should not be able to use any of the calculators if they do not provide name.

Calculator one is CALC1, Calculator two is CALC2, Calculator three is CALC3. (CALC3 will be created later)

Calculator one: Be sure to label “CALC1”

Prompt user to enter a weight for a patient in kilograms. Calculate both bolus and infusion rates based on weight of patient. The patient’s weight will be the only entry from the user. Use 3999 as a standard for calculating BOLUS: To calculate the BOLUS you will multiply 60 times the weight of the patient for a total number. IF the total number is less than 3999, then the BOLUS is the total number else it is 4000 Use 19.99 as a standard for calculating Maintenance infusion: To calculate the Maintenance infusion you will multiply 12 times the weight divided by 50 for a total number. IF the total number is less than 19.99 then the Maintenance infusion is the total number else it is 20 Use 50 and 100 KG as your test weight.

Two sample outputs: (user should see this data displayed)

Weight in kg: 50.00 kg
BOLUS 3000 units
Maintenance infusion of 12 ml/hour

Weight in kg: 100.00 kg
BOLUS 4000 units
Maintenance infusion of 20 ml/hour

Calculator two: Be sure to label “CALC2”

Prompt user to enter a weight for a patient in kilograms. Calculate infusion rate based on weight of patient.

To calculate the infusion rate you will multiply 12 times the weight divided by 50 for a total number. The end result will need to round up or down the whole number.

Example:

12 times 55 divided by 50 equals 13.2 should round down to 13 for
55 KG
13 ml/Hour

12 times 57 divided by 50 equals 13.68 should round up to 14 for
55 KG
14 mL/hour

Use 55 and 57 kg as your test weight.

Two sample outputs: (user should see this data displayed)

Weight in kg: 55 kg
Infusion of 13 ml/hour

Weight in kg: 57 kg
Infusion of 14 ml/hour
