java線程同步樣本

注意：先notify後waitpackage com.common.test1;public class Notify {private byte[] lock = new byte[0];public static void main(String args[]) {Notify mT = new Notify();mT.demo();}public void demo() {printThread a = new printThread("a");printThread b = new printThread("b");a.start();b.start();}class printThread extends Thread {public printThread(String name) {this.setName(name);}public void run() {synchronized (lock) {int i;for (i = 0; i < 100; i++) {if (i % 10 == 0 && 0 != i) {try {lock.notify(); // 喚醒另外一個進程lock.wait(); // 暫時釋放資源} catch (InterruptedException e) {e.printStackTrace();}}System.out.println(this.getName() + ": " + i);}if (i == 100) {lock.notify(); // 喚醒另外一個進程System.out.println(this.getName() + ": " + i);this.stop();}}}}}
