Java Regex除空格外的所有非单词字符

Question

This has Probably been asked before, but i want to split a string at every non word character except the white space in java. i do not have experience with regex in general and the wiki doesn't really help.

I've tried it with this: "[\\\\W][^\\\\s]" but that did not help.

Edit : how the String is read out of the file

StringBuilder sb = new StringBuilder();

        Scanner sc = new Scanner(getResources().openRawResource(R.raw.answers));

        try
        {
            while (sc.hasNext())
            {
                sb.append(sc.next());
            }
        } finally
        {
            sc.close();
        }

You can split using this regex:

String[] tok = input.split( "[\\W&&\\S]+" );

This will split on any non-word that is also a non-space character hence leaving aside space characters for split.

Check Character classes in Java Pattern reference .
