GTU OOP Program - 14

14). Write a program that creates an Array List and adds a Loan object , a Date object , a string, and a Circle object to the list, and use a loop to display all elements in the list by invoking the object’s to String() method.

import java.util.ArrayList;
 
class Loan {
    double amount;
 
    Loan(double amount) {
        this.amount = amount;
    }
 
    public String toString() {
        return "Loan with Amount " + this.amount;
    }
}
 
class Date {
    public String toString() {
        return "Date: " + java.time.LocalDateTime.now();
    }
}
 
class Circle {
    double radius;
 
    Circle(double r) {
        this.radius = r;
    }
 
    public String toString() {
        return "circle with radius " + this.radius;
    }
}
 
class Program_14 {
    public static void main(String[] args) {
        ArrayList<Object> arr_list = new ArrayList<Object>();
        arr_list.add(new Loan(1000));
        arr_list.add(new Date());
        arr_list.add(new String("Kanu Thakor"));
        arr_list.add(new Circle(5));
 
        for (int i = 0; i < arr_list.size(); i++) {
            System.out.println((arr_list.get(i)).toString());
        }
    }
}
