code for part1 is:

class firstClass{ //each object of this class represent a person String name,gender; int age; public firstClass() { //default constructor System.out.println("Inside default constructor"); } public firstClass(String n,String g, int a) { //constructor with argments name=n; gender=g; age=a; } //getter and setter functions public String getName() { return name; } public void setName(String name) { this.name = name; } public String getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } //methods which perform some operation on data void fiveYearsLater() { age+=5; //add 5 years to age } void display() { //display person details System.out.println("Name of the person is: "+name); System.out.println("Age of the person is: "+age); System.out.println("Gender of ther person is: "+gender); } } public class testClass { public static void main(String[] args) { firstClass object1=new firstClass(); //created using default constructor firstClass object2=new firstClass("david", "male", 21); //created using parametrized constructor object1.setName("Sharma"); //set values for object1 using setter functions object1.setGender("male"); object1.setAge(25); object1.display(); object1.fiveYearsLater(); object1.display(); //observe the age changes here object2.display(); } }

Part 3 (Abstract Class and Interface) (6 marks)

Consider the Class that you designed in Part#1 of this project and do the following:

1. Implement the Comparable and Cloneable interface for your class.
2. The Test class should create 5 instances (objects) of your class.
3. Store these instances in Array and ArrayList
4. Show the demo of sorting these objects stored in Array and ArrayList

Include the below in your project report:

1. Screenshot of relevant (Comparable and Cloneable) outputs.
2. Code for all classes.
