A Connectable Observable resembles an ordinary Observable, except that it does not begin emitting items when it is subscribed to, but only when its `connect()` method is called. In this way you can wait for all intended Subscribers to subscribe to the Observable before the Observable begins emitting items.

The following example code shows two Subscribers subscribing to the same Observable. In the first case, they subscribe to an ordinary Observable; in the second case, they subscribe to a Connectable Observable that only connects after both Subscribers subscribe. Note the difference in the output:

**Example #1:**
```groovy
def firstMillion = Observable.range( 1, 1000000 ).sample(7, java.util.concurrent.TimeUnit.MILLISECONDS);
```java
Observable firstMillion = Observable.range(1, 1000000).sample(7, java.util.concurrent.TimeUnit.MILLISECONDS);

firstMillion.subscribe(
{ println("Subscriber #1:" + it); }, // onNext
{ println("Error: " + it.getMessage()); }, // onError
{ println("Sequence #1 complete"); } // onCompleted
);

firstMillion.subscribe(
{ println("Subscriber #2:" + it); }, // onNext
{ println("Error: " + it.getMessage()); }, // onError
{ println("Sequence #2 complete"); } // onCompleted
);
firstMillion.subscribe(next -> System.out.println("Subscriber #1: " + next), // onNext
throwable -> System.out.println("Error: " + throwable), // onError
() -> System.out.println("Sequence #1 complete") // onComplete
);
firstMillion.subscribe(next -> System.out.println("Subscriber #2: " + next), // onNext
throwable -> System.out.println("Error: " + throwable), // onError
() -> System.out.println("Sequence #2 complete") // onComplete
);
```

## Getting Binaries

You can find binaries and dependency information for Maven, Ivy, Gradle, SBT, and others at [http://search.maven.org](http://search.maven.org/#search%7Cga%7C1%7Cg%3A"io.reactivex.rxjava2"%20AND%20"rxjava2").
