Question

JAVA - Write a program that creates an ArrayList and adds an Account object, a Date object, a ClockWithAudio object, a BMI object, a Day object, and a FigurePane object. Then display all elements in the list. Assume that all classes (i.e. Date, Account, etc.) have their own no-argument constructor.

Answer 1

Java Code :

import java.util.*;

//creating Account, Date, ClockWithAudio, BMI, Day and FigurePane classes
class Account { }
class Date { }
class ClockWithAudio { }
class BMI { }
class Day { }
class FigurePane { }

public class Main
{
   public static void main(String[] args) {
      
       //Creating Account object, a Date object, a ClockWithAudio object, a BMI object, a Day object, and a FigurePane object
       Account account = new Account();
       Date date = new Date();
       ClockWithAudio clockWithAudio = new ClockWithAudio();
       BMI bmi = new BMI();
       Day day = new Day();
       FigurePane figurePane = new FigurePane();
      
      
       //creating an arrayList
       ArrayList arrayList = new ArrayList();
      
       //Adding all objects to arrayList
       arrayList.add(account);
       arrayList.add(date);
       arrayList.add(clockWithAudio);
       arrayList.add(bmi);
       arrayList.add(day);
       arrayList.add(figurePane);
      
      
       //displaying the elements of arrayList
       for (int i=0;i<arrayList.size();i++)
       {
          System.out.println(arrayList.get(i));
       }
      
   }
}

Output :
