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;
}
}

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
