transaction.java

Java Classic Examples是我买的两本书：《JAVA经典实例》和《java入门经典源代码》里边附送光盘里带的源码

class Transaction
{
  // Transaction types
  public static final int DEBIT = 0;
  public static final int CREDIT = 1;
  public static String[] types = {"Debit","Credit"};

  // Constructor
  public Transaction(Account account, int transactionType, int amount)
  {
    this.account = account;
    this.transactionType = transactionType;
    this.amount = amount;
  }

  public Account getAccount()
  {  return account;  }

  public int getTransactionType()
  {  return transactionType;  }

  public int getAmount()
  {  return amount;  }

  public String toString()
  {
    return types[transactionType] + " A//C: " + ": $" + amount;
  }

  private Account account;
  private int amount;
  private int transactionType;
}
