Here's the Java code for the ProductDisplaySystem class, which produces the expected output by following the steps outlined in the case study questions. `java public class ProductDisplaySystem public static void main(String[] args) // Step 1: Write a Java program to display the title "Product Management System" // using System.out.println, along with decorative lines for formatting. System.out.println("============================================="); System.out.println("---------- PRODUCT MANAGEMENT SYSTEM ----------"); System.out.println("============================================="); // Step 2: Display a formatted header for the product table. // Using System.out.printf for precise column alignment. // %-9s: left-aligned string, 9 characters wide // %-15s: left-aligned string, 15 characters wide // %-11s: left-aligned string, 11 characters wide // %-8s: left-aligned string, 8 characters wide System.out.printf("%-9s%-15s%-11s%-8s%n", "ID", "Name", "Price", "Quantity"); // Separator line for the header System.out.println("============================================="); // Step 3: Display at least three product records using System.out.println // in a proper aligned format, matching the expected output data. // Using the same printf format string for consistent alignment. System.out.printf("%-9d%-15s%-11d%-8d%n", 101, "Laptop", 2500, 2); System.out.printf("%-9d%-15s%-11d%-8d%n", 102, "Mouse", 50, 5); System.out.printf("%-9d%-15s%-11d%-8d%n", 103, "Keyboard", 120, 3); // Step 4: Add a footer line after displaying all products. System.out.println("============================================="); // Step 5: Display a message "Thank you for using ITI Store System". // The message is manually centered within the 45-character width. System.out.println(" Thank you for using ITI Store System"); // Final decorative lines as per the expected output. System.out.println("============================================="); System.out.println("============================================="); ` Last free one today — make it count tomorrow, or type /upgrade for unlimited.
