java - RxJava Subscribe not working -


i have following code - 

package com.test.rxjava;  import org.reactivestreams.subscriber; import org.reactivestreams.subscription;  import io.reactivex.flowable;  public class app1 {      public static void main(string[] args) {          subscriber<integer> subscriber = new subscriber<integer>() {              @override             public void onsubscribe(subscription s) {             }              @override             public void onnext(integer t) {                 system.out.printf("entry %d\n", t);             }              @override             public void onerror(throwable t) {                 system.err.printf("failed process: %s\n", t);             }              @override             public void oncomplete() {                 system.out.println("done");             }          };         flowable.just(123).subscribe(subscriber);      }  }

i expecting execute code in onnext method.however nothing happens.however if replace last line below code, output. 

flowable.just(123).subscribe((t) -> system.out.println(t));

i not sure missing here. is. new rx world , use figure out wrong. in advance!

subscribers must request items. add s.request(long.max_value); in onsubscribe method, following:

@override public void onsubscribe(subscription s) {     s.request(long.max_value); }

see sample code , documentation here
