如果我想改变在这个实现ArrayList到LinkedList做我只需要改变

ArrayList<Character> characters = new ArrayList<Character>();

至

LinkedList<Character> characters = new List<Character>();

或者我该怎么做？

ArrayList<Character> characters = new ArrayList<Character>();
try {
    while((str = bufferedReader.readLine()) != null){
        char [] characterArray = str.toCharArray();

        for (int i = 0; i <  characterArray.length; i++){

            characters.add(characterArray[i]);
        }
    }
} catch (IOException e) {
    e.printStackTrace();
}
char [] patternArray = phrase.toCharArray();
ArrayList<Character> pattern = new ArrayList<Character>();
for (int i = 0; i <  patternArray.length; i++) {

    pattern.add(patternArray[i]);
}
