实验六：类的封装

实验六：类的封装

package zh;

public class Account {

private String account1;
private String name;
private String time;
private String IDname;
private double Balance; //定义变量余额
public Account(String account1,String name,String time,String IDname,double Balance)//开户
{this.account1=account1;
this.name=name;
this.time=time;
this.IDname=IDname;
this.Balance=Balance;
}
public int deposit(double amount) //存款
{
Balance=Balance+amount;
return 0;
}
public int withdraw(double amount)
{Balance=Balance-amount;
return 0;
}
public int enquire()//查询功能
{
System.out.println(name+" "+account1+" "+Balance);
return 0;
}
public void closeAccount() {//销户


}

public static void main(String[] args) {
// TODO Auto-generated method stub
Account a=new Account("wei","weili","2017.1.3","2018330001",20000);
Account b=new Account("zhang","zhangli","2017.4.6","2018330002",2000);
a.enquire() ;
System.out.println("存款500后：");
a.deposit(500.00);
a.enquire();
System.out.println("取款1000后：");
a.withdraw(1000.00);
a.enquire();
}

}

心得体会：无法将题目中所给的功能全部实现，编程时，对有些功能的程序很难实现，只能借鉴别人的。
