OOP-JAVA Practical 14

• PPS(C)
• JAvA

• Aim: 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 toString() method.
• Code:

  import java.util.ArrayList;
  import java.util.Date;
  public class practical14 {
      public static void main(String[] args) {
          class Loan{
              double ammount;
              Loan(double amt){
                  this.ammount=amt;
              }
              public String toString(){
                  return "Loan ammount = "+ammount;
              }
          }
          class Circle {
              double radius;
              Circle(double r){
                  this.radius=r;
              }
              public String toString(){
                  return "circle with radius "+radius+ "and Area is "+((3.14)*radius*radius);
              }
          }
          ArrayList<Object> arraylist=new ArrayList<Object>();
          arraylist.add(new Loan(2000.18));
          arraylist.add(new Date());
          arraylist.add(new Circle(2));
          arraylist.add(new String("Hello everyone"));
          for(int i=0;i<arraylist.size();i++){
              System.out.println(arraylist.get(i)+" ");
          }
      }
  }
