Using for loop to get all elements in an ArrayList?

Sun, 12 Feb 2012 03:03:05 -0700

Hi,

I'm trying to write a method that will use a for loop to iterate through all the positions in an ArrayList and add them to a String. I then want to return that String outside the for loop. Whenever I do this my for loop is ignored and what I initialised the String with is what is returned instead :S

  String wordPos = null;
	  for (int i = 0; i < position.size() - 1; i++)
	  {
		  wordPos = wordPos + position.get(i);
	  }
	  
	  return wordPos;

I hope you can tell me what is going wrong or a better way of doing this.

Thanks

Maybe you should try to declarate
wordPos = "";
And are you sure that you made your ArrayList a "String type".
I hope this helps you?
