Final answer:
The block of code should check if the positive number value is divisible by 5 using the modulo operator, and display the appropriate message.
Step-by-step explanation:
The block of code should have a condition that checks if the positive number value is divisible by 5 using the modulo operator. If the condition is true, it should display "Multiple of 5". If the condition is false, it should display "Incorrect". Here's an example:
int value = 15;
if (value % 5 == 0) {
System.out.println("Multiple of 5");
} else {
System.out.println("Incorrect");
}
