Q about the String class

Hi there.

Is there any method in the String class that will take 1234567899 and return - 123-456-7899 ?
Reason: get a user input for phone number and return it as a readable phone number format.

Thanks for you help! :)

I'm a beginner myself, but I'd probably read the string as a set of char's, and say after 3 char's add '-', after another 3 char's add '-'....

yup, it's working. Thank you!

Code java:

---

 
 public String getPhoneNumber(String p){
        return p.charAt(0) + p.charAt(1) + p.charAt(2)+  "-" +
        p.charAt(3) + p.charAt(4) + p.charAt(5) + "-" +      
        p.charAt(6) + p.charAt(7) + p.charAt(8) + p.charAt(9);
 
 
    }

seems like a mess though. is there a shortcut?

You could always check out String.format();


EDIT:

for example

String s = "TestString";
System.out.println(s.format("%s.%s", s.substring(0, 4), s.substring(4, s.length())));

that would output

Test.String

just what I needed.
Thank you very much!
