缓冲区代码
package Bank;
import java.util.LinkedList;
public class BankAccount {
static double sum=1000;
private LinkedList<Object> list = new LinkedList<>();
//存款
public void deposit() {
synchronized(list)
{
System.out.print(list.size());
while(list.size()>1) {
System.out.println("暂不支持存款");
try {
// System.out.print("wait");
list.wait();
} catch (InterruptedException e) {
e.printStackTrace();
//System.out.print("wait");
}
}
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() {
synchronized(list)
{
while(list.size()==0) {
// int money=50;
// sum=sum-money;
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.out.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();
}
}
