java多线程之生产者消费者
遇到问题,就要针对解决。多线程之生产者消费者实现。
消费者
public class Consumer implements Runnable { private Account account; public Consumer(Account accoun) { this.account = accoun; // TODO Auto-generated constructor stub } @Override public void run() { while (true) { synchronized (account) { if (account.getAmount() >= 1) { int balance = account.getAmount(); balance--; account.setAmount(balance); System.out.println(Thread.currentThread().getId() + "扣钱," + "余额: " + balance); account.notify(); } else { try { System.out.println(Thread.currentThread().getId() + "钱不够: " + account.getAmount()); account.wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } } }
生产者
public class Producer implements Runnable { private Account account; public Producer(Account accoun) { this.account = accoun; // TODO Auto-generated constructor stub } @Override public void run() { while (true) { synchronized (account) { if (account.getAmount() <= 5000000) { int balance = account.getAmount(); balance++; account.setAmount(balance); System.out.println(Thread.currentThread().getId() + "加钱," + "余额: " + balance); account.notify(); } else { try { System.out.println(Thread.currentThread().getId() + "钱满了: " + account.getAmount()); account.wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } } }
测试类
public class TestConPro { public static void main(String[] args) { Account account = new Account(); Producer pro = new Producer(account); Consumer con = new Consumer(account); Thread tpro = new Thread(pro); Thread tcon = new Thread(con); tpro.start(); tcon.start(); } }
