In this video, we solve a Java practice problem that simulates a simple receipt calculator. We walk through the program step by step, starting with reading user input for a subtotal and coupon status, applying a conditional discount, calculating tax, and formatting the final total for output.
This problem is designed to reinforce foundational Java skills and common patterns you’ll use throughout the course, especially when working with user input, numeric calculations, and decision-making logic.
Skills practiced in this video:
Using Scanner for user input
Working with double values for calculations
Writing if statements for conditional logic
Applying percentage-based discounts and tax
Formatting numeric output using printf
Basic input validation and edge-case handling (extension)
This walkthrough focuses on reasoning and structure rather than memorizing code, so you can apply the same approach to similar problems later in the course.
