如何向Observable.interval()添加延迟？

import io.reactivex.Observable;
import java.util.concurrent.TimeUnit;

public class DelayExample {
    public static void main(String[] args) {
        Observable.interval(1, TimeUnit.SECONDS)
                .delay(5, TimeUnit.SECONDS)
                .subscribe(System.out::println);

        // 等待一段时间，以便观察结果
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
