Validate Email Address with GUI

Structure of the Problem Requirements 

In this problem we will learn how to make Graphic User Interface for Validation an Email Address . Before this we upload this program in command prompt now we have attractive GUI for it. The Program will check that rather the user input email is valid or not ? The Program accept email only when it is written in proper email format. To achieve this we used string matches function and follow the email format. Here is the source code of this problem which help you in better understanding.

Source Code     

public class NewJFrame extends javax.swing.JFrame {

     * Creates new form NewJFrame
    public NewJFrame() {

     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
