Exception Handling - Java

Implement the following program with exception handling.

--------------------------HealthProfile.java-----------------------------------------------------

import java.util.Calendar; //Calendar used to calculate age

public class HealthProfile { private String firstName; //Instance Variable private String lastName; //Instance Variable private String gender; //Instance Variable private int month; //Instance Variable private int day; //Instance Variable private int year; //Instance Variable private int height; //Instance Variable private int weight; //Instance Variable
