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

}
public void setBalance(int money) { // 设定帐户馀额

// 提款方法

//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 ...
}
