[java] Fetch first element which matches criteria

How to get first element that matches a criteria in a stream? I've tried this but doesn't work

this.stops.stream().filter(Stop s-> s.getStation().getName().equals(name));

That criteria is not working, the filter method is invoked in an other class than Stop.

public class Train {

private final String name;
private final SortedSet<Stop> stops;

public Train(String name) {
    this.name = name;
    this.stops = new TreeSet<Stop>();
}

public void addStop(Stop stop) {
    this.stops.add(stop);
}

public Stop getFirstStation() {
    return this.getStops().first();
}

public Stop getLastStation() {
    return this.getStops().last();
}

public SortedSet<Stop> getStops() {
    return stops;
}

public SortedSet<Stop> getStopsAfter(String name) {


    // return this.stops.subSet(, toElement);
    return null;
}
}


import java.util.ArrayList;
import java.util.List;

public class Station {
private final String name;
private final List<Stop> stops;

public Station(String name) {
    this.name = name;
    this.stops = new ArrayList<Stop>();

}

public String getName() {
    return name;
}

}

I think this is the best way:

this.stops.stream().filter(s -> Objects.equals(s.getStation().getName(), this.name)).findFirst().orElse(null);

When you write a lambda expression, the argument list to the left of -> can be either a parenthesized argument list (possibly empty), or a single identifier without any parentheses. But in the second form, the identifier cannot be declared with a type name. Thus:

this.stops.stream().filter(Stop s-> s.getStation().getName().equals(name));

is incorrect syntax; but

this.stops.stream().filter((Stop s)-> s.getStation().getName().equals(name));

is correct. Or:

this.stops.stream().filter(s -> s.getStation().getName().equals(name));

is also correct if the compiler has enough information to figure out the types.
