Basically I try to extract only the 2nd element from the list of tuples. Scala has a very nice solution to this (which somewhat looks like this x._2) but I don't know how I can do this in Java.
public static ArrayList<House> house = new ArrayList<>(Arrays.asList(new House(321321, 2.5),
new House(456544, 3.0),
new House(789687, 4.0));
Assuming your House
class has getters for these values eg:
public class House {
private final int value1;
private final double value2;
public House(final int value1, final double value2) {
this.value1 = value1;
this.value2 = value2;
}
public int getValue1() {
return value1;
}
public double getValue2() {
return value2;
}
}
You can do a map and collect to get the second value:
final List<Double> value2s = house.stream().map(House::getValue2).collect(Collectors.toList());
