title: I made a char[] with split and am trying to make it into a String again, but I don't know why this is not working
body: <p>Why will this code not print out a string?</p>
  
  <pre><code>String s = "My name is Jack";
      String[] arr = s.split("");
      char[] a = Arrays.toString(arr).toCharArray();
  System.out.println(a);
  System.out.println(new String(a));
  </code></pre>
