Question about the task Pharmacy
Java Core, Level 7, Lesson 10
Archived
Do not dig too deep...You should call buy() in the Pharmacy class and sell() in the Person class. It's quite obvious, if you read only the methods' names. However, if you read this two (or see the output), the other pairing is more logical.

Under discussion
Last Requirement not met Like so many other people, it looks just like it's supposed to. I even tested it with numbers and I still get what appears to be the correct output. I haven't the slightest idea what the hold up is, which sucks as I thought I had this on the first try, and now I've tried it like 4 times.
