****Create a Person class conforming to the diagram above. A person is assigned an immutable social security number at birth, and a name which can be changed later. People are born with an age of zero. The setAge method should set the person’s age. A senior citizen is someone over 65 years old.

****Create a driver that asks the user, in a loop, for a person’s name, ssn, and age. You should create an instance of your Person class and print the new person to the console. You should stop when the user enters the word ”quit”.

Person ssn: String name: String age: int Person (ssn: String, name: String) getName(): String setName(name: String) set Age (age: int get Age(): int isSenior Citizen(): boolean toString String

Solution

Hi, please find my implementation.

Please let me know in case of any issue.

public class Person {

  

   // instance variables

   private String ssn;

   private String name;

   private int age;

  

   public Person(String ssn, String name) {

       this.ssn = ssn;

       this.name = name;

   }

   public String getName() {

       return name;

   }

   public int getAge() {

       return age;

   }

   public void setName(String name) {

       this.name = name;

   }

   public void setAge(int age) {

       this.age = age;

   }

  

   public boolean isSeniorCitizen(){

       return age > 65;

   }

  

   @Override

   public String toString() {

       return \"SSN: \"+ssn+\", Name: \"+name+\", and Age: \"+age;
