忽略StringTokenizer Java上的特殊字符

Question

I want to ignore special characters like , " ; : using string tokenizer. For example, if I enter:

He said, "That's not a good idea."

output should be:

He
Said
that
s
not
a
good
idea

This is my current code

class Q_03
{
    public static void main(String[] argv)
    {
        System.out.print("Enter text to break :- ");
        Scanner sc = new Scanner(System.in);
        String x = sc.nextLine();
        StringTokenizer url = new StringTokenizer(x, " ");              

        while(url.hasMoreTokens())
        {
            System.out.println(url.nextToken());
        }
    }
}

You can replace that special characters with regex like this:

class Q_03 {
    public static void main(String[] argv) {
        System.out.print("Enter text to break :- ");
        Scanner sc = new Scanner(System.in);
        String x = sc.nextLine().replaceAll("[|;:,'\"]", " ");
        StringTokenizer url = new StringTokenizer(x, " ");

        while (url.hasMoreTokens()) {
            System.out.println(url.nextToken());
        }
    }
}

You can add to this regexp "[;:,'\\"]" whatever symbols you want, but some special symbols (like " ) must have been escaped with backslash \\" .
