public class Request {
private String business;public Request(String business) {
this.businessbusiness;
}
public String toString() {
return this.business;
}
}
import java.util.concurrent.ThreadLocalRandom;
import java.util.concurrent.TimeUnit;public class TaskHandler implements Runnable{
private Request request;public TaskHandler(Request request) {

try {
TimeUnit.SECONDS.sleep(ThreadLocalRandom.current().nextInt(10));
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}Override
public void run() {
System.out.println(Begin handle request);
slowly();
System.out.println(End handle request);
