Cohesion

• CashRegister, as described above, involves two concepts: cash register and coin
• Solution: Make two classes:
  

  public class Coin
  {
     public Coin(double aValue, String aName){ . . . }
     public double getValue(){ . . . }
     . . .
  }
  
  public class CashRegister
  {
     public void enterPayment(int coinCount, Coin coinType) { . . . }
     . . .
  }
