Bymadwithcode

Universal Library wants to extract the book code for the arrangements and easy retrieval .

Write a program to implement this scenario to help them to extract.

Business Rules:

The book code should be length of 18 . else print “ Invalid Book Code “

1 – The first 3 position is for Department Code .

2 – The next 4 position is for Publication Years

3 – The next 5 position is for Number of Pages.

4 – The next 6 position is for Book Id

The valid Department code is  101, 102, 103 else print “ Invalid Department Code”

The valid Year of Publication is 1900 to 2020 else print “ Invalid Year “

The valid Page Number is from 00001 to 99999 else print “ Invalid Page Numbers”

The valid Book ID is character followed by numbers else print “ Invalid Book ID”

Create a class Program and get the book code as input and implement the above functionalities

Sample Input 1 :

Enter the book code of length 18

101202012345J12345

Sample Output 1:

Department Code        : 101

Year of Publication     : 2020

Number of Pages        : 12345

Book ID                      : J12345

Sample Input 2 :

Enter the book code of length 18

102201945678G54321

Sample Output 2:

Department Code        : 102

Year of Publication     : 2019

Number of Pages        : 45678

Book ID                      : G54321

Sample Input 3 :

Enter the book code of length 18

102201945678G

Sample Output 3:

Invalid Book Code

Sample Input 4:

Enter the book code of length 18

104201945678G54321

Sample Output 4:

Invalid Department Code

Year of Publication     : 2019

Number of Pages        : 45678
