accountimpl.java

CORBA分布式编程一个简单实例

// 账户对象的具体实现
public class AccountImpl extends Bank.AccountPOA {
    // 属性定义
    protected float balance;

    // 构造方法，按指定余额创建新的账户
    public AccountImpl(float bal) {
        balance = bal;
    }
    // 往账户中存款
    public void deposit(float amount) {
        balance += amount;
    }
    // 从账户中取款，不足余额则返回false
    public boolean withdraw(float amount) {
        if (balance < amount)  return false;
        else {
            balance -= amount;
            return true;
        }
    }
    // 查询账户余额
    public float getBalance() {
        return balance;
    }
}
