可以实现数据保存功能，数据将保存在文件。

（2）源程序
package ATM;
/*
* 银行账户类
*/
public abstract class Account {
private long id; //银行卡号
private String password; //密码
private String name; //姓名
private String personId; //身份证
private int accountType; //账户类型（0，储蓄 1，信用卡）
private double balance; //账户金额
public Account(){
//无参构造方法
super();
}
