String [] to String

Question

I have a text file and i want to read each word into an ArrayList<Dictionary> but I have to leave commas, dashes, dots etc. This is the code so far for this purpose:

Scanner sc2 = null;    
while (sc2.hasNextLine()) {
    Scanner s2 = new Scanner(sc2.nextLine());
    while (s2.hasNext()) {
        String s = s2.next();
        String[] tokens = s.split("\\W+");
        s  = tokens.toString();
        Dictionary.add(s);
    }
}

The problem is that when I execute the printing code :

for (int i = 0; i < Dictionary.size();i++) {
    System.out.println(Dictionary.get(i));
}

I get the following:

[Ljava.lang.String;@ea2f77
[Ljava.lang.String;@ea6137
[Ljava.lang.String;@ea639

Etc. for every word. I belive that the problem is s = tokens.toString(); but i do not know how to fix it. Thank you!

Oh i forgot to mention that for some reason, eclipse does not let me use Arrays. . Everytime i try to use it, importing the library i get errors. — Maria

Also note that it looks to me like you could get rid of the split statement and the second scanner by simply iterating over sc2.hasNext() and adding each word to the dictionary. — elhefe

@Maria maybe your eclipse do not have whole source of java :P — Vighanesh Gursale

tokens is an array of Strings, and as such its toString() method returns what you see in your output. You need to iterate over each String in tokens and add them to the Dictionary individually, e.g.

for (int i = 0; i < tokens.length; i++) {
    Dictionary.add(tokens[i]);
}

if you wanted to avoid for loops; then just use java.util.Arrays--

s = Arrays.toString(s.split("\\W+"));

This is a question that has already been asked, but here's the answer:

String punctutations = ".,:;";//add all the ones you want.
if(punctutations.contains(letter[a])) //If the character at letter[a] contains a punctuation mark
