    Hello there everyone, I have this piece of code here, and whenever I try to compile it, I get the error "cannot find symbol - method replaceAll(java.lang.String,java.lang.String). I am not very good at Java and I can't seem to figure out why it won't work,
    
 public static ArrayList<String> convertFileLinesToSentences(ArrayList<String> filelines) {         ArrayList<String> sentenceWithoutWhitespace = new ArrayList<String>();         sentenceWithoutWhitespace = filelines.replaceAll("\\s","");         return sentenceWithoutWhitespace;     } 

    In my previous method just before this one, I also use the .replaceAll method and there are no troubles with it, any and all help is appreciated, thank you.

    
  public static String cleanWord(String word)     {         String cleanWord = word;         cleanWord = word.replaceAll("[^A-Za-z0-9]", "");         return cleanWord.toString();     } 


    Is This A Good Question/Topic? 0

    filelines has the type ArrayList which doesn't have a replaceAll method
    Maybe you wanted to enumerate the ArrayList and call replaceAll on each individual String?

    So the replaceAll method can only be used on strings? In that case, I guess I better go read up on enumerating =) Thanks, I couldn't continue because it wouldn't work.
