title: Putting a space in a string
body: <p>Assuming I have a String like "MikeJackson" I am trying to figure out a way to put a space in between so it becomes "Mike Jackson". And then applying the same method to another string say "JohnBull" would give me back "John Bull". This is the code I came up with:</p>
  
  <pre><code>public class Test{
  
      public Test(){
  
      }
  public void sep(String s){
      s = s + " ";
     char[] charArray = s.toCharArray();
     int l = s.length();
  for (int i = 0; i &lt; l; i++){
      char p = ' ';
  
      if(Character.isUpperCase(s.charAt(0))){
          continue;   
      }
      else if (Character.isUpperCase(s.charAt(i))){
          int k = s.indexOf(s.charAt(i));
          charArray[l] = charArray[--l];
          charArray[k-1] = p;
      }
      //System.out.println(s.charAt(i));
  }
  }
      public static void main (String args[]){
  
      Test one = new Test();
  
      one.sep("MikeJackson");
      }  
  }
  </code></pre>
  
  <p>My idea was to add a space to the String so that "MikeJackson" becomes "Mike Jackson " and then shift the characters on place to the right (check for where I find an uppercase) ignoring the first uppercase. Then put a character ' ' in place of the character 'J' but shift 'J' to the right. That's what I was trying to achieve with my method but it looks I need some guidelines. If anyone could help. Thanks.</p>
