skip()

The skip() operator does the opposite of the take() operator. It will ignore the specified number of emissions and then emit the ones that follow.  If I wanted to skip the first 90 emissions of an Observable, I could use this operator, as shown in the following code snippet:

import io.reactivex.Observable;

public class Launcher {
      public static void main(String[] args) {

        Observable.range(1,100)
          .skip(90)
          .subscribe(i -> System.out.println("RECEIVED: " + i));
      }
}

The output of the following code snippet is as follows:

RECEIVED: 91
RECEIVED: 92
RECEIVED: 93
RECEIVED: 94
RECEIVED: 95
RECEIVED: 96
RECEIVED: 97
RECEIVED: 98
RECEIVED: 99
RECEIVED: 100

Just like the take() operator, there is also an overload accepting a time duration. There is also a skipLast() operator, which will skip the last specified number of items (or time duration) before the onComplete() event is called. Just keep in mind that the skipLast() operator will queue and delay emissions until it confirms the last emissions in that scope.
