RxJava - NewThread Scheduler

O método Schedulers.newThread () cria e retorna um Scheduler que cria um novo Thread para cada unidade de trabalho.

Schedulers.newThread () Exemplo

Crie o seguinte programa Java usando qualquer editor de sua escolha em, digamos, C: \> RxJava.

ObservableTester.java

import java.util.Random;

import io.reactivex.Observable;
import io.reactivex.schedulers.Schedulers;

public class ObservableTester  {
   public static void main(String[] args) throws InterruptedException {
      Observable.just("A", "AB", "ABC")
         .flatMap(v -> getLengthWithDelay(v)
         .doOnNext(s -> System.out.println("Processing Thread " 
            + Thread.currentThread().getName()))
         .subscribeOn(Schedulers.newThread()))
         .subscribe(length -> System.out.println("Receiver Thread " 
            + Thread.currentThread().getName() 
            + ", Item length " + length));

         Thread.sleep(10000);
   }
   protected static Observable<Integer> getLengthWithDelay(String v) {
      Random random = new Random();
      try {
         Thread.sleep(random.nextInt(3) * 1000);
         return Observable.just(v.length());
      } catch (InterruptedException e) {
         e.printStackTrace();
      }
      return null;
   }
}

Verifique o resultado

Compile a classe usando javac compilador da seguinte forma -

C:\RxJava>javac ObservableTester.java

Agora execute o ObservableTester da seguinte maneira -

C:\RxJava>java ObservableTester

Ele deve produzir a seguinte saída -

Processing Thread RxNewThreadScheduler-1
Receiver Thread RxNewThreadScheduler-1, Item length 1
Processing Thread RxNewThreadScheduler-2
Receiver Thread RxNewThreadScheduler-2, Item length 2
Processing Thread RxNewThreadScheduler-3
Receiver Thread RxNewThreadScheduler-3, Item length 3
