用Java编写一个银行帐户管理的程序
不好意思，时间有限，帮你写了父类acount 和 信用卡类 Checking，其他派生类只是成员方法有所区别。
大同小异。
写的不好，仅供参考：
class Acount{ private String username; // private String password; // 都是私有属性，设置为private private float money=0f; // public String getUsername() { //getter和setter 对属性的读取操作 return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public float getMoney() { return money; } public void setMoney(float money) { this.money = money; } public void withdrawal(float withdrawal,String password){ //取钱操作 if(this.password==password){ if(withdrawal>money){ System.out.print("账户余额不足，不可支取！\n 余额为:"+money); }else{ System.out.print("支取了现金:"+withdrawal); this.money=this.money-withdrawal; } } } public void deposit(float deposit){ //存钱操作 System.out.print("存入 了："+deposit+"\n 目前余额为:"+(money+deposit)); this.money=this.money+deposit; } }
class Checking extends Acount{ private String username; private String passowrd; private float money=0f; private String status; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassowrd() { return passowrd; } public void setPassowrd(String passowrd) { this.passowrd = passowrd; } public float getMoney() { return money; } public void setMoney(float money) { this.money = money; } public void checkStatus(){ if(this.money<0){ System.out.print("信用卡已透支 \n 透支了"+(""+this.money).substring(1)); //(""+this.money).substring(1) 不要负号 }else{ System.out.print("信用卡未透支 \n 余额为:"+this.money); } } public void withdrawal(float withdrawal,String password){ //覆盖了父类的 withdrawal方法 if(this.passowrd==password){ if(this.money==-5000||this.money>-5000){ System.out.print("信用卡严重透支，不可以再取！请及时还款。
"); }else{ System.out.println("支取了现金:"+withdrawal); this.money=this.money-withdrawal; System.out.println("余额为："+this.money); } } } }
求一个面向对象编写的一个简易JAVA的银行管理系统
1. 添加一个静态全局遍历Map ACCOUNTINFO ;
2. 创建一个用户实体类User 包括以下几个字段id(辨识用户唯一性的) ,name ,password,money
3. 在静态块中初始化为ACCOUNTINFO里面存值也就存储User对象
4. 然后就可以做登录账户 存储 转款的操作了。
