Splitting words into letters in Java [duplicate]

Question

How can you split a word to its constituent letters?

Example of code which is not working

 class Test {
         public static void main( String[] args) {
             String[] result = "Stack Me 123 Heppa1 oeu".split("\\a");                                                                                   

             // output should be
             // S
             // t
             // a
             // c
             // k
             // M
             // e
             // H
             // e
             // ...
             for ( int x=0; x<result.length; x++) {
                 System.out.println(result[x] + "\n");
             }
         }
     }

The problem seems to be in the character \\a. It should be a [A-Za-z].

Answer 1

You need to use split("");.

That will split it by every character.

However I think it would be better to iterate over a String's characters like so:

for (int i = 0;i < str.length(); i++){
    System.out.println(str.charAt(i));
}

It is unnecessary to create another copy of your String in a different form.

Answer 2

"Stack Me 123 Heppa1 oeu".toCharArray() ?
