篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了多线程之生产消费相关的知识，希望对你有一定的参考价值。
package mysd;
public class Main {
public static void main(String[] args) {
DianY dy=new DianY();
ChangJ cj=new ChangJ(dy);
Xiaof xf=new Xiaof(dy);
Thread td=new Thread(cj);
Thread td2=new Thread(cj);
Thread td1=new Thread(xf);
Thread td11=new Thread(xf);
// td2.start();
td.start();
td1.start();
td11.start();
}
}package mysd;
public class DianY {
int top=30;
public synchronized void add(){
if(this.top>=50){
try {
this.wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}else{
top++;
System.out.println("生产者生产的"+top+"个产品。");
notifyAll();
}
}
public synchronized void de(){
if(this.top<=0){
try {
this.wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}else{
top--;
System.out.println("消费的"+top+"个产品。");
notifyAll();
}
}
}
package mysd;
public class ChangJ implements Runnable{
private DianY dy;
public ChangJ(DianY dy){
this.dy=dy;
}
@Override
public void run() {
for(;;){
try {
Thread.sleep(50);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
dy.add();
}
}
}
package mysd;
public class Xiaof implements Runnable{

public Xiaof(DianY dy) {
// TODO Auto-generated constructor stub
