1. Using Java 8 stream

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

public class Example1 {

    public static void main(String[] args) {

        String text = "abc";

        List<Character> list = text.chars()
                .mapToObj(c -> (char) c)
                .collect(Collectors.toList());

        System.out.println(list); // [a, b, c]
    }
}

Output:

[a, b, c]

Note:
In Java there is more then 1 way to create stream of characters from String, take a look on this post:

Java 8 - convert char[] to Stream<Character>

2. Explicit iteration

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

public class Example2 {

    public static void main(String[] args) {

        String text = "abc";

        List<Character> list = new ArrayList<>();
        for (char c : text.toCharArray()) {
            list.add(c);
        }

        System.out.println(list); // [a, b, c]
    }
}

Output:

[a, b, c]
