银行取钱的java代码 银行存取款java代码

IT技术账户

使用JAVA编写一个简单的银行存取款程序package com.lw.thread;
/*
银行账户类Account（不能透支） ， 
包含账号id（10~16位数字），密码password（6位数字），户主姓名name，余额balence
*/
public class Account {
private String id;
private int password;
private String name;
private double balence;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public int getPassword() {
return password;
}
public void setPassword(int password) {
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getBalence() {
return balence;
}
public void setBalence(double balence) {
this.balence = balence;
}
/*
* 默认构造账户信息为：1111111111111111,666666，钱三多，888888.88 。
*/
public Account() {
super();
this.id = "1111111111111111";
this.password = 666666;
this.name = "钱三多";
this.balence = 888888.88;
}
/*
* 另一个构造方法带4个参数分别初始化4个属性（带数据有效性验证） 。
*/
public Account(String id, int password, String name, double balence) {
this.id = id;
this.password = password;
this.name = name;
this.balence = balence;
}
/*
* 查询余额
*/
public static double selectMoney(Account account) {
return account.getBalence();
}
/*
* 存钱
*/
public static String setMoney(Account account, double balence) {
if (balence0) {
return "存钱失败，请正确放入！";
}
double d = balence + account.getBalence();
account.setBalence(d);
return "您存入了" + balence + "元，现账户余额为+" + d;
}
/*
* 取钱
*/
public static String getMoney(Account account, double balence) {
double d = account.getBalence();
if (balenced) {
return "您的余额不足！";
}
account.setBalence(d - balence);
return "您取出了" + balence + "元，现账户余额为+" + account.getBalence();
}
}
如何用Java线程实现银行的存款取款问题最好能写出编出的具体程序AccountTest.java class BankAccount//定义银行账户类BankAccount{privatestaticint amount =2000;//账户余额最初为2000publicvoiddespoit(int m)//定义存款的方法{amount=amount+m;System.out.println("晓明存入["+m+"元]");}public void withdraw(int m)//定义取款的方法{amount=amount-m;System.out.println("张新取走["+m+"元]");if(amount0)System.out.println("***余额不足！***)；public int balance()//定义得到账户余额的方法{return amount;}}classicCustomerextendsThread {String name;BankAccount bs;//定义一个具体的账户对象publicCustomer(BankAccount b,String s){name=s;bs=b;}public static void cus(String name,BankAccount bs)//具体的账户操作方法{if(name.equals("小明"))//判断用户是不是小明{try{for(int i=0;i6;i++)//用户晓明则向银行存款6次，每次1000元{Thread.currentThread().sleep((int)(Math.random()*300));bs.despoit(1000);}}catch(InterruptedException e){}}else{try{for(int i=0;i6;i++)//用户不是小明则从银行取款6次，每次1000元{Thread.currentThread().sleep((int)(Math.random()*300));bs.withdraw(1000);}}catch(InterruptedException e){}}}public void run()//定义run方法}cus(name,bs);}}public classAccountTest{public static void main(String [] args) throws InterruptedException{BankAccount bs=new BankAccount();Customer customer1=new Customer(bs,"小明");Customer customer2=new Customer(bs,"张新");Thread t1=newThread(customer1);Thread t2=newThread(customer2);t1.Start（）；t2.start();Thread.currentThread().sleep(500);}}
