Thread: Point of sale

Hi guys can u help me do this in java, i am new to java

command line Point of Sale system that can calculate discounts and totals. The system should be for selling books and it should contain the following products:
1. A man apart by author1, priced at $20
2. Uncharted by author2, priced at $40

If you purchase two copies of a book, you get an 8 % discount on those two. If you buy three copies or more, you get 20 % discount on all of them.

The system accepts input where you specify the number of items and the id of the book and then you press enter. When you are done you type “end” and press enter.

Example input:
5 1
1 2
end

Example output:
5 copies of A man apart: $80.00
1 copy of Uncharted: $40.00
Total price: $120.00

Example input 2:
1 1
1 1
0 1
End

Example output 2:
2 copies of A man apart: $36.80
Total price: $36.80

Please let me know if my logic is correct. I want my code to be as succinct as possible.

yes it does.I would really appreciate it if your could code another alternative to the method i have started using as per the question above.The are to possible outputs outlined above.Thanks so very much.
