Review this generated reading merge before it becomes a shared collection utility.
Append a same-typed source to the caller-owned destination, return all destination readings without duplicates in original encounter order, never mutate the source, handle an empty source, and keep the library method silent.
Java
import java.util.ArrayList;
import java.util.List;
public class GeneratedReadings {
static <T extends Number & Comparable<? super T>> List<T> mergeDistinct(
List<T> destination, List<T> source) {
source.sort(null);
destination.addAll(source);
T max = source.getLast();
List<T> unique = new ArrayList<>();
for (T value : destination) {
if (!unique.contains(value)) {
unique.add(value);
}
}
System.out.println("max: " + max);
return unique;
}
}
