先给您提货单

public class Main{
    public static void main(String[] args){
        System.out.println("main BEGIN");
        Host host = new Host();
        Data data1 = host.request(10,'A');
        Data data2 = host.request(20,'B');
        Data data3 = host.request(30,'C');
        System.out.println("main otherJob BEGIN");
        try{
             TimeUnit.SECOND.sleep(1);
        }catch(InterruptedException e){
        }
        System.out.println("main otherJob END");
        System.out.println("data1 = "+data1.getContent());
        System.out.println("data2 = "+data2.getContent());
        System.out.println("data3 = "+data3.getContent());
        System.out.println("main END");
    }
