Library Fine Calculation
Calculate library fine based on number of days a book is overdue.

Java Library Fine Calculation Program
This program helps you to learn the fundamental structure and syntax of Java programming.
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter number of days late: ");
int days = sc.nextInt();
double fine;
if (days <= 0) {
fine = 0;
} else if (days <= 5) {
fine = days * 1.0;
} else if (days <= 10) {
fine = 5 * 1.0 + (days - 5) * 2.0;
} else {
fine = 5 * 1.0 + 5 * 2.0 + (days - 10) * 5.0;
}
System.out.println("Fine = " + fine);
sc.close();
}
}Output
Enter number of days late: 8 Fine = 11.0
Understanding Library Fine Calculation
We use slabs of days to apply different fine rates as the delay increases.
