Check valid Email Id using Regex in Java

Any email id is of the form: abc.xyz@company.com or abc23.xyz@company.co.uk or abc_34year@company.com . One can validate these emails using regular expression in Java. Below is a program which can replace the email ids with a word 'EMAIL'.

package com.Nur;

public class Emailvalidation {

    /**
     * @param args
     * @author nur.haldar
     * @return
     */
    public static final String EXAMPLE_TEST = "This is the emailid: nur.haldar@comviva.com" +
            " from where" +
            " the mail was sent to nurjamia@gmail.com. Please check " +
            "the two email ids are valid or not";
    public static void main(String[] args) {
        //String nameRegex = "[A-Z][a-z]+\s\s?[A-Z][\.]?\s\s?[A-Z][a-z]+";
        String pattern = "(\\w)(\\s+)([\\.,])";
        pattern = "\\b[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}\\b";
        System.out.println(EXAMPLE_TEST.replaceAll(pattern, "EMAIL"));

    }

}

Output: This is the email id: EMAIL from where the mail was sent to EMAIL. Please check the two email ids are valid or not
