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 (balence 0) {
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 (balence d) {
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{private static int amount =2000; //账户余额最初为2000public void despoit(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public Customer(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=new Thread(customer1);Thread t2=new Thread(customer2);t1.Start();t2.start();Thread.currentThread().sleep(500);}}
JAVA编写银行账户程序摸拟银行账户的存\取款操作
public class ATM {
public static void main(String[] args) {
// 开立帐号
Account account = new Account();
// 在 account 中存 10,000 元
account.setBalance(10000);
// 检查 account 中的存款
System.out.println("帐户原始金额 : " + account.getBalance() + " 元");
// 小明, 小华与小英一起对 account 进行提款的动作
WithDraw s1 = new WithDraw("小明", account, 5000); // 小明 在 account 中提 5000 元
WithDraw s2 = new WithDraw("小华", account, 2000); // 小华 在 account 中提 2000 元
WithDraw s3 = new WithDraw("小英", account, 4000); // 小英 在 account 中提 4000 元
s1.start();
s2.start();
s3.start();
}
}
//帐户
class Account {
private int balance; // 帐户馀额
public int getBalance() { // 取得帐户馀额
return balance;
}
public void setBalance(int money) { // 设定帐户馀额
balance = money;
}
// 提款方法
public void withDraw(Account account, int withdrawMoney) {
String tName = Thread.currentThread().getName(); // tName=提款人
System.out.println(tName + " 开始提款 ... ");
boolean withDrawStatus; // 提款状态 说明:false=提款失败, true=提款成功
synchronized(ATM.class) {
int tmpBalabce = account.getBalance(); // 取得最新帐户馀额
//用 for-loop 模拟提款时系统所花的时间
for(double delay=0;delay99999999;delay++) {
// ... 提款进行中 ...
}
tmpBalabce = tmpBalabce - withdrawMoney; // 最新帐户馀额 - 欲提款金额 (用来判断是否馀额足够的依据)
if (tmpBalabce 0) { // 判断是否馀额足够
withDrawStatus = false;
System.out.println("....................");
System.out.println(" 帐户馀额不足!");
System.out.println("....................");
} else {
withDrawStatus = true;
account.setBalance(tmpBalabce); // 回存account最後剩馀金额
}
}
System.out.println(tName + "的交易单:");
System.out.println("\t欲提款金额:" + withdrawMoney + "元");
System.out.println("\t帐户馀额:" + account.getBalance());
if(withDrawStatus == true){
System.out.println(tName + " 完成提款 ... ");
} else {
System.out.println(tName + " 提款失败 ... ");
}
System.out.println("-------------------------------");
}
}
// 提款类别
class WithDraw extends Thread {
private Account account; // 帐号
private int withdrawMoney; // 欲提款的金额
// tName:执行绪名称, account:Account物件名称, withdrawMoney:欲提款金额
public WithDraw(String tName, Account account, int withdrawMoney) {
setName(tName);
this.account = account;
this.withdrawMoney= withdrawMoney;
}
public void run() {
// 执行提款动作(account:帐号, withdrawMoney 欲提款金额)
account.withDraw(account, withdrawMoney); // 执行提款动作
}
}
