    The array at position 2 (the a) has not a real char value. So you must either:

    	    // stepthrough the sentence array, get the first character
    	    // of each string @ each index, and store in firstLetters array
    	    for (int x = 0; x < sentence.length; x++)
    	    { 
    	      // only grab the 1st letter if word is > 1 character in length
    	      if (sentence[x].length() > 1)
    	      {
    	        firstLetters[x] = sentence[x].charAt(0);
    	      }else{
    	    	  firstLetters[x] = ' ';
    	      }
    	    }

    fill it with a default ' ' at the above position of your code or you must check against the int value of a char. In java a char is an int value, simply said

    	    // append the letter @ each index in firstLettersp[] array to the end of
    	    // each word @ ea. relative index in sentence[x] array
    	    for (int x = 0; x < sentence.length; x++)
    	    {
    	      if ( firstLetters[x] != 0)
    	      {
    	       sentence[x] = sentence[x] + firstLetters[x];
    	      }
    	    }

    Try to output (int) aChar for a better understanding of it. It's a kind of working with ascii-tables and so on.

    Looks like the error starts earlier:

    sentence[]: [i, have, a, dog]

    firstLetters array: [ , h, , d]


    The first letters are white space. You need to trim it at that point.
