Java -使用递归将其他列表作为函数参数填充列表值

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

public class RecursiveListFill {
    public static void main(String[] args) {
        List<Integer> sourceList = List.of(1, 2, 3, 4, 5);
        List<Integer> targetList = new ArrayList<>();

        fillList(sourceList, targetList);

        System.out.println(targetList);
    }

    public static void fillList(List<Integer> source, List<Integer> target) {
        if (source.isEmpty()) {
            return;
        }

        int value = source.get(0);
        target.add(value);

        List<Integer> remaining = source.subList(1, source.size());
        fillList(remaining, target);
    }
}
