Question about the task Mixed-up bytes
Java Syntax, Level 16, Lesson 2
Under discussion

I understand that's a more beautiful way, but I'd like to use the try-catch-finally formula just in order to better understand how all this works. So, the validator implies that I'm not using the newInputStream and newOutp

Question about the task Pharmacy
Java Core, Level 7, Lesson 10
New
possible bug in the correct solution The allDrugs map is static but the methods of DrugController are not. Making its methods synchronised still allows simultaneous access to the allDrugs via 2 different DrugController objects. Either the methods should be static too or or synchronized(DrugController.class) should be used.

Same as the suggested solution but doesn't work Well, this quite simple code of mine doesn't only produce the expected output but also fully coincides with the suggested solution (I checked it line by line). Still, it does not pass the verification. Could there be a bug?
