The document describes an event handling program in Netbeans IDE that allows a user to input values to calculate the areas of different shapes. The program takes length and width values to calculate the area of a rectangle, a side value to calculate the area of a square, and base and height values to calculate the area of a triangle. It then displays the computed areas. It also describes a program that displays a user's name or "UNIDENTIFIED" when an enter button is clicked based on input. Finally, it outlines a product order program that allows a user to input quantities, calculates totals, displays discount percentages based on total amount, and shows discounted amounts.
