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 定义一个类实现银行账户 包括变量 "帐号""存款余额"，方法:"存款"，"取款"和"查询

private double money=0L ;

public void addMoney(double money){

this.money=this.money+ money;

System.out.println("余额"+this.money);

}

public void outMoney(double money){

if(moneythis.money){

System.out.println("余额不足！");

}else{

this.money=this.money- money;

System.out.println("取出"+money+"元，余额"+this.money);

}

}

public void getMoney(){

System.out.println("余额"+this.money);

}
