Person class

This class implements the Comparable interface $($details below$).$

This class has instance variables and accessor methods for Date born, Date died, and Name name. It has the following methods:

public Person $($Date born, Name name$)$: This constructor throws IllegalPersonException exceptions if either born or name is null.

public void die$($Date dateOfDeath$)$: this method sets the died instance variable to the dateOfDeath provided.

public boolean isAlive$()$: this method returns true if the Person is alive; otherwise returns false.

public int compareTo$($Person p$)$: this method satisfies the requirements from implementing the Comparable interface. Younger people are "larger". Note: this method must use its born variable's compareTo$($Date d$)$ method.

This class overrides the public String toString$()$ method, which returns a String in one of these two exact formats:

a$)$ Alive people example: "Tiger Woods was born $1975-12-30$ and is still alive"

b$)$ Dead people example: "Albert Einstein was born $1879-03-14$ and died $1955-04-18"$

Use the name variable's getPrettyName$()$ method, and the born$/$died getYyyyMmDd$()$ method.
