Login App

Login App is a simple Java application that demonstrates how to create a login window using Swing. It takes a username and password input and checks if the credentials match predefined values ("username" and "password"). If they match, it prints a successful login message, otherwise, it prints a failed login message.

Features

• Graphical User Interface (GUI):

  • A login screen with fields for username and password.
  • A login button to submit the entered credentials.

• Login Functionality:

  • Verifies the entered username and password against predefined values.
  • Provides feedback on successful or failed login attempts.

Technologies Used

• Java - The main programming language used to build the application.
• Swing - A Java library for building graphical user interfaces (GUIs).
• SpringLayout - Used to arrange components in the login panel.

Getting Started

Prerequisites

To run this app, you need:

• JDK (Java Development Kit) installed on your machine.
• An IDE like IntelliJ IDEA, Eclipse, or NetBeans (optional, but recommended).

Steps to Run

1. Clone or download the repository to your local machine.
2. Open the project in your IDE or text editor.
3. Compile and run the LoginApp class to launch the login window.

Code Explanation

• CommanConstants: This class contains constant values for the application, such as the application name, frame size, and text field size.

• LoginGUI: The LoginGUI class is responsible for creating the login window using Swing components:

  • A JLabel for the username and password fields.
  • JTextField for entering the username.
  • JPasswordField for entering the password.
  • A JButton for submitting the credentials.
  • SpringLayout is used to manage the layout of the components.

• LoginApp: This is the entry point of the application. It launches the LoginGUI window.

Example Usage

• Open the app, and enter the following credentials:

  • Username: username
  • Password: password

• If the credentials are correct, the console will display:

  LOGIN SUCCESSFUL!
  

• If the credentials are incorrect, the console will display:
