double price = 19.99;
System.out.printf("Price: %d", price); // Prints: Price: 19Answer and explanation
Correct answer
B. It prints the double as an integer.
Why
Using '%d' with a double in 'printf' will not throw an exception but rather print the double value as an integer by truncating the decimal part, which might not be the intended behavior.
