Syntax error Validate Phone with Java Regular Expressions

Validate Phone with Java Regular Expressions

In order to match the phone using regular expression, we use the matches method in Java. The java.lang.String.matches() method returns a boolean value which depends on the matching of the String with the regular expression.

Declaration − The java.lang.String.matches() method is declared as follows −

public boolean matches(String regex)

Let us see a program to validate a phone number with regular expressions −

Example

 Live Demo

public class Example {
   public static void main( String[] args ) {
      System.out.println(phone("+91 1023456789"));
   }
   // validate zip
   public static boolean phone( String z ) {
      return z.matches("\+[0-9]*\s+\d{10}" );
      // taking an assumption that a phone number is of ten digits
   }
}

Output
