Answer
Use 'printf()' with '%.2f'. Frame the concept in practical terms so you can explain it during interview discussion.
To display a double value with two decimal places, use 'System.out.printf()' with '%.2f'. This is essential in e-commerce for showing prices consistently, like a price of 19.9 appearing as 19.90.
