1. Using Java 8 stream

Edit

xxxxxxxxxx
 
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:

xxxxxxxxxx
 
[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:

2. Explicit iteration

Edit

xxxxxxxxxx
 
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]
    }
}
