ArrayList of Characters

arraylist, character, java

Solution

In your case, `words.charAt()` is enough.

  import java.util.ArrayList;

  public class Test{

       String words = new String("HELLO GOODBYE!");
       ArrayList<Character> sample = new ArrayList<Character>();

       for(int i = 0; i<words.length(); i++){
           sample.add(words.charAt(i));
       }
  }

Problem

I want to create an ArrayList of character objects based off the characters in a string of letters. But, I can't seem to figure out how to fill that ArrayList to match the String. I've been trying to have it iterate through the string so that later, if I change the content of the string it'll adjust. Regardless, no matter what I do I'm getting some sort of syntax error. Could anybody please guide me in the right direction? Thanks a bunch! ``` import java.util.ArrayList; import java.text.CharacterIterator; //not sure if this is necessary?? public class Test{ //main method String words = new String("HELLO GOODBYE!"); ArrayList<Character> sample = new ArrayList<Character>(); for(int i = 0; i<words.length(); i++){ sample.add((char)Character.codePointAt(sample,i)); } } ```
