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

// Defines a customer account
public class Account
{
  // Constructor
  public Account(int accountNumber, int balance)
  {
    this.accountNumber = accountNumber;            // Set the account number
    this.balance = balance;                        // Set the initial balance
  }

  // Return the current balance
  public int getBalance()
  {  return balance;  }

  // Set the current balance
  public void setBalance(int balance)
  {  this.balance = balance;  }

  public int getAccountNumber()
  {  return accountNumber;  }

  public String toString()
  {
    return "A//C No. "+accountNumber+" : $"+balance;
  }

  private int balance;                             // The current account balance
  private int accountNumber;                       // Identifies this account
}
