如何不通过引用将元素从一个ArrayList复制到另一个？

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> sourceList = new ArrayList<>();
        sourceList.add(1);
        sourceList.add(2);
        sourceList.add(3);

        ArrayList<Integer> destinationList = new ArrayList<>();
        destinationList.addAll(sourceList);

        System.out.println("Source List: " + sourceList);
        System.out.println("Destination List: " + destinationList);
    }
}

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> sourceList = new ArrayList<>();
        sourceList.add(1);
        sourceList.add(2);
        sourceList.add(3);

        ArrayList<Integer> destinationList = new ArrayList<>();
        for (Integer element : sourceList) {
            destinationList.add(element);
        }

        System.out.println("Source List: " + sourceList);
        System.out.println("Destination List: " + destinationList);
    }
}

import java.util.ArrayList;
import java.util.Collections;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> sourceList = new ArrayList<>();
        sourceList.add(1);
        sourceList.add(2);
        sourceList.add(3);

        ArrayList<Integer> destinationList = new ArrayList<>(Collections.nCopies(sourceList.size(), null));
        Collections.copy(destinationList, sourceList);

        System.out.println("Source List: " + sourceList);
        System.out.println("Destination List: " + destinationList);
    }
}

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> sourceList = new ArrayList<>();
        sourceList.add(1);
        sourceList.add(2);
        sourceList.add(3);

        List<Integer> destinationList = sourceList.stream()
                                                  .collect(Collectors.toList());

        System.out.println("Source List: " + sourceList);
        System.out.println("Destination List: " + destinationList);
    }
}
