This feature is very important and useful in all programs. It includes user levels and restrictions for system and data protection against unnecessary data manipulation.  It depends on how the programmer creates these features.

This tutorial shows the source code and how to use it. Before we start, make sure to subscribe to our newsletter or share these articles on any social media platform.

In the code, we use try-catch exception for error handling, if-statement to check if the user name and password are valid, if true the FORM will display and hide the login form.

To create a Login form, it is required to use JFrame Form. Inside your JFrame form add the element jLabel, jTextField, and jButton. jLabel for the User Name and Password Label, jTextField to accept the user name and password and a button to execute the login. Remember that this feature uses MySQL server any version but tested on version 5.1
