arraylist of characters in java code example

Example 1: arraylist of characters

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));
       }
  }

Example 2: saving String character in arraylist

//storing String character in arraylist
import java.util.*;
public class Basic_Practice2 {
	public static void main(String[] args) {
		
		String s = "Hello";
      
		ArrayList<String> al = new ArrayList<String>();
      //storing String character in arraylist
		for(int i = 0; i < s.length(); i++)
			{
				al.add(Character.toString(s.charAt(i)));
			}
      // printing ArrayList
		System.out.println(al);//[H,e,l,l,o]
		
	}
}
