    private int gridDimensions;

    public WordSearchPuzzle(ArrayList<String> userSpecifiedWords)
    {
        this.puzzleWords = userSpecifiedWords ;

    }

    private void createPuzzleGrid()
    {
        int i;
        for(i = 0; i < puzzleWords.size() ; i++){
            letterCount = puzzleWords.size() + letterCount ;
        }
        gridDimensions = letterCount * 2;
        puzzle = new char[gridDimensions][gridDimensions] ;
    }

Change each string to a charArray.

for(String item : ArrayList){
  item.toCharArray();
}
