java多线程间的通信实例

----线程间的通信

public class ListAdd1 {
private volatile static List list = new ArrayList();
public void add(){
list.add("bjsxt");
}
public int size(){
return list.size();
}

public static void main(String[] args) {
final ListAdd1 list1 = new ListAdd1();

Thread t1 = new Thread(new Runnable() {
public void run() {
try {
for (int i = 0; i < 10; i++) {
list1.add();
System.out.println("当前线程："+Thread.currentThread().getName()+ "添加了一个元素");
Thread.sleep(500);
}
} catch (Exception e) {
e.printStackTrace();
}
}
},"t1");
Thread t2 = new Thread(new Runnable() {
public void run() {
while(true){
if(list1.size()==5){
System.out.println("当前线程收到通知："+Thread.currentThread().getName()+ "list.size==5线程停止");
throw new RuntimeException();//抛出运行时异常
}
}
}
},"t2");

t1.start();
t2.start();
}

}
运行结果：
