Part 3 | Computer Screen Lock Application in Java Swing | Read & Store Password
In this video, we implement password storage and retrieval for our Computer Screen Lock Application using Java Swing.
You’ll learn how to:
Store a password securely in a file using Java NIO
Read the saved password from the system
Use the user home directory for portability
Handle file creation and overwrite safely
Separate password logic into a clean, reusable class
This is an important step before connecting the password with the unlock authentication logic in upcoming parts.
