How can a string be transformed into a list of individual characters?

In Java, a string can be converted into a list of individual characters in several ways. One simple way is to use the toCharArray() method, which returns an array of characters, and then convert it into a list.

Example:

import java.util.*;

public class Main {
    public static void main(String[] args) {
        String str = "Example";
        // Convert string to array of characters
        char[] chars = str.toCharArray();

        // Create a list of characters
        List<Character> charList = new ArrayList<>();
        for (char c : chars) {
            charList.add(c);
        }

        System.out.println(charList);
    }
}

You can also use Java 8 Stream API:

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

This method is convenient and concise.
