class Resource{private boolean ready=false;
public void processWork(Worker worker){
while(!worker.isFinished()){
System.out.println(“waiting for a worker”);
try{
Thread.sleep(1000);
}catch(InterruptedException e){

}
}

}
public boolean is Ready(){

}
private void setReady(boolean ready){

}
}
class Worker{
private boolean finished=false;
public void consumeResource(Resource resource){
while(!resource.isReady()){
System.out.println(“waiting for a resource”);
try{
Thread.sleep(1000);
}catch(InterruptedException e){

}
}
setFinished(true);
}
public boolean is Finished(){
return finished;
}
private void setFinished(boolean finished){
this.finished=finished;
}
}
And the code fragment:
Resource resource=new Resource();
Worker worker=new Worker();
Thread t1=new Thread(()->resource.processWork(worker));
Thread t2=new Thread(()->worker.consumeResource(resource));
t1.start();
t2.start();
代码片段执行时会发生什么情况?
