                           .mapToObj(c -> (char) c)
                           .toArray(Character[]::new);

Answer 3

import java.util.Arrays;

class Main {
    public static void main(String[] args) {
        String str = "abcde";

        char[] primitiveArray = str.toCharArray();
        Character[] charArray = new Character[primitiveArray.length];
        for (int i = 0; i < primitiveArray.length; i++) {
            charArray[i] = primitiveArray[i]; 
        }
        
        System.out.println(Arrays.toString(charArray)); 
    }
}
