我找到了下一个代码:
public static void main(String args[]) {
Producer producer = new Producer();
producer.start();
new Consumer(producer).start();
}
}
class Producer extends Thread {
static final int MAXQUEUE = 5;
private Vector<String> messages = new Vector<String>();
public void run() {
try {
while (true) {
putMessage();
sleep(1000);
}
} catch (InterruptedException e) {
}
}
private synchronized void putMessage() throws InterruptedException {
while (messages.size() == MAXQUEUE)
wait();
messages.addElement(new java.util.Date().toString());
notify();
}
public synchronized String getMessage() throws InterruptedException {
notify();
while (messages.size() == 0)
wait();
String message = (String) messages.firstElement();
messages.removeElement(message);
return message;
}
}
class Consumer extends Thread {
Producer producer;
Consumer(Producer p) {
producer = p;
}
public void run() {
try {
while (true) {
String message = producer.getMessage();
System.out.println("Got message: " + message);
sleep(2000);
}
} catch (InterruptedException e) {
}
}
因此,据我了解消息传递 - 只是不使用共享资源,而是像上面的示例引用一样使用从一个对象到另一个对象进行通信。我对吗?
