Define a class called Library with the following description:
Instance Variables/Data Members:
int accNum — stores the accession number of the book.
String title — stores the title of the book.
String author — stores the name of the author.
Member methods:
Accession Number Title Author
Write a main method to create an object of the class and call the above member methods.
- (a)void input() — To input and store the accession number, title and author.
- (b)void compute() — To accept the number of days late, calculate and display the fine charged at the rate of Rs. 2 per day.
- (c)void display() — To display the details in the following format:
