Code Explanation

The code begins by importing the necessary packages for creating a GUI application with Java Swing. A JFrame named "Demo" is created as the main window, and its layout is set to FlowLayout for easy arrangement of components. A JLabel is added to label the JTextField where users will enter their email ID. The JTextField is initialized with a width of 20 columns, and its text alignment is set to the right using the setHorizontalAlignment() method. Both the label and text field are added to the frame. Finally, the frame's size is set to 550x250 pixels, and it is made visible to display the GUI.
