Real-World Project: Creating a Simple Greeting Application

Summary

The tutorial demonstrates creating a simple GUI in Java using Swing. It starts by setting up a new Java project in Eclipse and a class with a main method. The GUI class includes a constructor to initialize a JFrame for the window. The example adds a button and a label, where clicking the button changes the label text. This covers basic concepts of graphical user interfaces in Java.
