Return Multiple Values

Methods can only ever return one type of thing. This usually retricts you to only ever returning one int or one String.

But if you make a class that has multiple fields you can use that to return more than one piece of information.¹

class Location {
    double latitude;
    double longitude;
}

Location findTreasureIsland() {
    Location location = new Location();
    location.latitude = 40.2085;
    location.longitude = -3.713;
    return location;
}

void main() {
    Location treasureIsland = findTreasureIsland();
    System.out.println(
        "Treasure island is located at " +
            treasureIsland.latitude +
            " " +
            treasureIsland.longitude +
            "."
    );
}
