多线程下，两个线程交替打印0 -100，使用wait()和notify()
public class ThreadTest{
private static final Object lock = new Object();
static class ThreadA extends Thread{
@Override
public void run() {
for (int i = 0; i < 100; i = i+2) {
synchronized (lock){
lock.notify();
System.out.println(Thread.currentThread().getName()+" "+i);
try {
lock.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
static class ThreadB extends Thread{
@Override
public void run() {
for (int i = 1; i < 100; i = i+2) {
synchronized (lock){
lock.notify();
System.out.println(Thread.currentThread().getName()+" "+i);
try {
lock.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
public static void main(String[] args) {
new ThreadA().start();
new ThreadB().start();
}
}
运行结果：
