Question

How can I extract only the numeric values from the input string?

For example, the input string may be like this:

String str=\"abc d 1234567890pqr 548         


        

Answer 1

You could do something like:

Matcher m = Pattern.compile("\\d+").matcher(str);
while (m.find()) {
   System.out.println(m.group(0));
}
