}

}

list.add(new Object());

int money=300;

sum=sum+money;

System.out.println(Thread.currentThread().getName()+"存入了"+money+"元"+"现在共有存款"+sum);

list.notifyAll();

}

}

//取款

public void withdrawal() {

System.out.println(Thread.currentThread().getName()+"暂时不支持取款");

try {

list.wait();

} catch (InterruptedException e) {

e.printStackTrace();

}

}

list.remove();

int money=200;

if(sum>200)

{

sum=sum-money;

System.outhttp://.println(Thread.currentThread().getName()+"取出了"+money+"元"+"现在共有存款"+sum);

}else {

System.out.println("账户余额不足");

}

list.notify();

}

}

}

存款代码

package Bank;

public class Deposit implements Runnable {

private BankAccount bankAccount1;

public Deposit() {}

public Deposit(BankAccount bankAccount1) {

this.bankAccount1=bankAccount1;

}

@Override

public void run() {

// TODO Auto-generated method stub

while(true) {

try {

Thread.sleep(2000);

bankAccount1.deposit();

} catch (InterruptedException e) {

// TODO: handle exception

e.printStackTrace();

}

}

}

}

取款代码

package Bank;

public class Withdrawal implements Runnable{

private BankAccount bankAccount;

public Withdrawal() {}

public Withdrawal(BankAccount bankAccount)

{

this.bankAccount=bankAccount;

}

@Override

public void run() {

// TODO Auto-generated method stub

while(true)

{

try {

Thread.sleep(3000);

bankAccount.withdrawal();

} catch (InterruptedException e) {

// TODO: handle exception

e.printStackTrace();

}

}

}

}

主函数代码

package Bank;

public class Main {

public static void main(String[] args) {

BankAccount bankAccount1=new BankAccount();

Thread d1=new Thread(new Deposit(bankAccount1));

Thread d2=new Thread(new Deposit(bankAccount1));

Thread d3=new Thread(new Deposit(bankAccount1));

Thread w1=new Thread(new Withdrawal(bankAccount1));

Thread w2=new Thread(new Withdrawal(bankAccount1));

Thread w3=new Thread(new Withdrawal(bankAccount1));

d1.start();

d2.start();

d3.start();

w1.start();

w2.start();

w3.start();

}
