Apache email validator: import and usage problem

[Zulfi Khan <zu...@yahoo.com.INVALID>]

Hi,
I am trying to use the Apache email validator code.
 
I tried to use two import statements to import the apache email validator for testingemail addresses but they are not working:



import org.apache.commons.validator.routines.EmailValidator;
https://stackoverflow.com/questions/624581/what-is-the-best-java-email-address-validation-method

and 

importorg.apache.commons.validator.routines.InetAddressValidator;

https://github.com/apache/commons-validator/blob/master/src/main/java/org/apache/commons/validator/EmailValidator.java







packagecom.mycompany.validatename;

//importorg.apache.commons.validator.*; ERROR, How to correct?

//importorg.apache.commons.validator.routines.InetAddressValidator; ERROR,how to coorect?

importjava.util.regex.Matcher;

importjava.util.regex.Pattern;

importjavax.swing.JOptionPane;




public classValidateNameForm extends javax.swing.JFrame {




 publicValidateNameForm() {

 initComponents();

 }

 

 private voidjTF1ActionPerformed(java.awt.event.ActionEvent evt) { 

 // TODO addyour handling code here:

 } 

 private voidCheckIfInputValid(String input, String regex){

 String s;

 Patternpattern = Pattern.compile(regex);

 s =input.trim();

 Matchermatcher = pattern.matcher(s);

 JOptionPane.showMessageDialog(null, "Input "+s+" isvalid " + 

 String.valueOf(matcher.matches())); 

 }

 private voidjButton1ActionPerformed(java.awt.event.ActionEvent evt) { 

 StringemailAddress= jTF1.getText();

 booleanisValidEmail =EmailValidator.getInstance().isValid(emailAddress);//SYNTAX ERROR

 

 } 




 public staticvoid main(String args[]) {

 try {

 for(javax.swing.UIManager.LookAndFeelInfo info : 

 javax.swing.UIManager.getInstalledLookAndFeels()) {

 if("Nimbus".equals(info.getName())) {

 javax.swing.UIManager.setLookAndFeel(info.getClassName());

 break;

 }

 }

 } catch(ClassNotFoundException ex) {

 :

 :

 }




 // Variablesdeclaration - do not modify 

 privatejavax.swing.JButton jButton1;

 privatejavax.swing.JLabel jLabel1;

 privatejavax.swing.JTextField jTF1;

 // End ofvariables declaration 

}

You might want to add the required dependency.
If you are working with maven (recommended) then here is a minimal pom that
will work finding the jar from maven central.

----
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="
