Question
Design and implement a Java program to create a list of patients’ records in a medical practice. The program will maintain a current list of patients records within a given multi-disciplinary practice. Patient data for the program includes a patient's ID, first name, last name, e-mail address (valid emails contain an @ and .), age, gender, weight, height and an array of doctors used by the patient and their specialty (the maximum number of specialists should be five). Error checking of all data is required. The program should allow entry of patient information via the keyboard with the maximum number of patients being 30, but the list can contain less. Once the data is entered the program should then allow the user to retrieve the entire list of patients' or an individual patient’s information via the patient’s ID number.
The program in both instances should display all of the information listed above plus the program should calculate the patient’s Body Mass Index (BMI = (weight in pounds/(height in inches X height in inches) X 703) and display it along with the category the patient falls under.
The categories are based upon the following: Below 18.5 - Underweight 18.5 – 24.9 - Normal 25 – 29.9 - Overweight 30 and above - Obese Make sure to submit the following: documentation code screen shots or files of I/O executable file (JAR file)
Completely confused about this assignment..hints will help too.
