Java 8 Stream – Converting For Loop to Stream Example

I would like a simple example for Java 8 Streams to understand it. I have this code that returns a free taxi. I would like to replace this for loop with equivalent code that uses Java 8 streams :

private List<Taxi> taxis = new ArrayList<Taxi>();

Taxi scheduleTaxi(){
    for (Taxi taxi : taxis) {
        if (taxi.isFree()) {
            return taxi;
        }
    }
    return null;
}

I iterate over a list of taxis, and evaluate if taxi respects the condition. If the condition applies, I stop the loop and return taxi.

Any suggestions?
