我对多线程很天真,并且正在尝试学习它的概念。这是我对生产者-消费者问题的实现。如果它不正确/粗鲁/任何其他可以改进我的设计的建议,请看一下并建议我。
static int data = 0;
static Object obj1 = new Object();
static class Producer implements Runnable {
public void run() {
produce();
}
void produce() {
while (true) {
if (data < 5){
synchronized(obj1){
System.out.println("Producing Data. Now Data is "+data++);
obj1.notifyAll();
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else{
try {
System.out.println("Producer inactive");
synchronized(obj1){
obj1.wait();
}
System.out.println("Producer active");
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
}
static class Consumer implements Runnable{
public void run(){
consume();
}
void consume() {
while (true) {
if (data > 0){
synchronized(obj1){
System.out.println("Consuming Data. Now Data is "+data--);
obj1.notifyAll();
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else{
try {
System.out.println("Consumer Inactive");
synchronized(obj1){
obj1.wait();
}
System.out.println("Consumer Active");
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
}
