Here’s a simple Java program that accepts the  number of late days and calculates the fine or displays the membership cancellation message:

import java.util.Scanner;

public class LibraryFine {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

// Input number of late days

System.out.print(“Enter number of days late: “);

int daysLate = sc.nextInt();

if (daysLate <= 0) {

System.out.println(“No fine. Book returned on time.”);

} else if (daysLate <= 5) {

System.out.println(“Fine is ₹5”);

} else if (daysLate <= 10) {

System.out.println(“Fine is ₹10”);

} else if (daysLate <= 30) {

System.out.println(“Fine is ₹50”);

} else {

System.out.println(“Membership cancelled due to delay over 30 days.”);

}

}

}

📌 Sample Runs:

Input: 3

Output: Fine is ₹5

Input: 12

Output: Fine is ₹50

Input: 35

Output: Membership cancelled due to delay over 30 days.
