Question

Your Java program should perform the following things:

1. Take the input from the user about the patient name, weight, birthdate, and height.

2. Calculate Body Mass Index.

3. Display person name and BMI Category.

1. If the BMI Score is less than 18.5, then underweight.

2. If the BMI Score is between 18.5-24.9, then Normal.

3. If the BMI score is between 25 to 29.9, then Overweight.

4. If the BMI score is greater than 29.9, then Obesity.

4. Calculate Insurance Payment Category based on BMI Category.

1. If underweight, then insurance payment category is low.

2. If Normal weight, then insurance payment category is low.

3. If Overweight, then insurance payment category is high.

4. If Obesity, then insurance payment category is highest.

5. Implement exception handling using try-catch.

6. Include the finally block.

You need to submit the following things:

• An entire Java solution

• An output screenshot created using Microsoft Word
