I am trying to split an inputted number such as (123) 456-7890.
String [] split = s.split(delimiters);
I have been searching the web for ways of delimiting the area code inside the set of the parentheses but I haven't found anything that works for my case. I do not know if the array is messing up with it printing either. The array is not required but I did not know what else to do since it is required to use the split method.
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class HelloWorld{
public static void main(String[] args){
String phoneNumber = "(123)-456-7890";
String pattern = "\\((\\d+)\\)-(\\d+)-(\\d+)";
Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(phoneNumber);
if (m.find())
System.out.println(m.group(1) + " " + m.group(2) + " " + m.group(3));
}
}
You can try it here.
split method. Also the phone number does not have a hyphen after the parenthesis: i is "(123) 456-7890" not "(123)-456-7890".If I understand your question, you could use a Pattern like (XXX) XXX-XXXX where X is a digit. You can also use {n} to require n occurences. You group with (). Something like,
String str = "(123) 456-7890";
Pattern p = Pattern.compile("\\((\\d{3})\\) (\\d{3})-(\\d{4})");
Matcher m = p.matcher(str);
if (m.matches()) {
String areaCode = m.group(1);
String first3digits = m.group(2);
String last4digits = m.group(3);
System.out.printf("(%s) %s-%s%n", areaCode, first3digits,
last4digits);
}
Gives your requested output of
(123) 456-7890
or, if you must use split you might first remove the ( and ) with a call to replaceAll and something like
String str = "(123) 456-7890";
String[] arr = str.replaceAll("[()]", "").split("[ -]");
System.out.printf("(%s) %s-%s%n", arr[0], arr[1], arr[2]);
which also gives your requested output of
(123) 456-7890
split method.
() so you don't need to replace them.
String(s) in the array. With my approach you do not.this works:
String s= "(123) 456-7890";
String[] parts = s.split("[()\\- ]");
System.out.println("(" + parts[1] + ") " + parts[3] + "-" + parts[4]);
If you must use the split method:
String s= "(123) 456-7890"
String[] split = s.split("[()-]");
System.out.println("(" + split[1] + ")" + split[2] + "-" + split[3]);
(123, so then you doSystem.out.println("(" + NumberTokens[0] + ")")you get two braces. Either add(to delimeters and start from element 1 or just print without"("System.out.println("123) 456-7890".replaceAll("\\D", ""));
