Enhance the CashRegister class by adding separate methods enterDollars, enter-

Quarters, enterDimes, enterNickels, and enterPennies.

Use this tester class:

public class CashRegister Tester { public static void main (String[] args) { } Cash Register register = new CashRegister(); register.recordPurchase(20.37); register.enterDollars (20); register.enterQuarters (2); System.out.println("Change: System.out.println("Expected: + register.giveChange () ); 0.13");
