1. 先創建Customer類
2.聲明三個私有屬性 firstName lastName account
3.提供一個共有構造器 編寫獲取get方法 放回相應屬性
4. 聲明setaccount方法對account賦值
5. 聲明getaccount（）方法來獲取account值

          class Customer{

                 private String   firstName ;
                 private String   lastName ;
                 private  Account account;

                 public Customer(String   firstName,String   lastName){
                 this.firstName = firstName;
                 this.lastName= lastName;
                  }

                 public String getFirstName() {
                 return firstName;
                  }

                 public String getLastName() {
                 return lastName;
                  }

                  public void setAccount(Account account){
                  this.account = account;
                  }

                  public void getAccount(){
                  return account;
                  }
}   

測試類

                    class test { 

                    public static void main(String[] args) {

                    System.out.println("Creating the customer Jane Smith.");
                    Customer customer = new Customer("Jane", "Smith");
                     //code
                    System.out.println("Creating her account with a 500.00 balance.");
                    Account account = new Account(500);
                    //code
                    System.out.println("Withdraw 150.00");
                    account.withdraw(150);
                    //code
                    System.out.println("Deposit 22.50");
                    account.Deposit (150);
                    //code
                    System.out.println("Withdraw 47.62");
                    account.withdraw(47.62);
                    //code
                    // Print out the final account balance
                    System.out.println("Customer [" + customer.getLastName()
                           + ", " + customer.getFirstName()
                           + "] has a balance of " + account1.getBalance());

                }       
            }
