. Then, add code that: declares and creates an ArrayList of Purchase objects named purchases (make sure to add import java.util.ArrayList at the top of your source code) creates and adds Purchase objects to the purchases list for each of the following: a customer named Cathy with a balance of $100.00 a customer named Ben with a balance of $234.56 a customer named Jorge with a balance of $2.49 a customer named Wanda with a balance of $32.32 a customer named Freddie with a balance of $400.00 prints out the final purchases list (hint: you can use a single call to System.out.println() with the purchases list)

/* Purchase.java */

public class Purchase {
// instance variable
private String name;
private double balance;
// constructor
public Purchase(String name, double balance) {
this.name = name;
this.balance = balance;
}
// to string method
@Override
public String toString() {
return name + " has a balance of $" + balance;
}
  
}

/* Store.java */

import java.util.ArrayList;

public class Store {

public static void main(String[] args) {
// arraylist
ArrayList<Purchase> purchases = new ArrayList<>();
// add object
purchases.add(new Purchase("Cathy",100.00));
purchases.add(new Purchase("Ben",234.56));
purchases.add(new Purchase("Freddie",400.00));
// print list
for (Purchase object:purchases) {
System.out.println(object.toString());
}
}
}
