title: Split String Into Small Parts [JAVA]
body: <p>I have a string that says Bingo and I want to break it to smaller parts and make each of them a String array, for example;<br/><br/></p>
  
  <p><code>String s = "BINGO"</code><br/></p>
  
  <p>I want it so to be like this;<br/></p>
  
  <pre><code>String s[] = new String[s.length];
  s[0] = B;
  s[1] = I;
  s[2] = N;
  s[3] = G;
  s[4] = O;
  </code></pre>
  
  <p>I tried this but it failed;<br/></p>
  
  <pre><code>public static void main(String[] args) {
  
  
      String sentence = "BINGO";
      String words[] = sentence.split("a-zA-Z");
  
     for (String word : words) {
      System.out.println(word);
  }
  </code></pre>
  
  <p>It just prints out "BINGO" whereas I want to split them, now what regex should I use ?</p>
