Hi,

Regular expression can be used for replacing in combination with the replaceAll function of String.

Following regular expression can be used:

"[^\\d]"

Here is complete program:

public class ReplaceNonDigit {

    public static void main(String[] args) {
        String data = "Hello you can contact me at my number 999999999. I am in Delhi India.";
        data = data.replaceAll("[^\\d]", "");
        System.out.println(data);

    }

}

Thanks
