    its not really possible to create a string from a null array either.

    if the array was not null then we can create a string by catenating each element together:
    Java Code:
    String[] temp = null;
    
    // something here would initialize temp[] and set array values right.
    
    // convert array to a single string
    String st3 = null;
    if (temp != null) {
      StringBuilder b = new StringBuilder();
      for (String s : temp) {
        if (s != null) {
          b.append(s);
        }
      }
      st3 = b.toString();
    }

    Please don't post the same question in multiple sub-forums. Stick with a one. I've closed this thread, and please deals with the other thread in New to Java. If you want to clarify anything regarding this, send me a PM.
