Hi, what is wrong with the createRandomGamePiece method?Hi, Despite the fact I had to manually write the whole GamePieceFactory method (where the task said at level 12 that it will complete it by its own), I don't know why it does not validate now. Can you help? Thanks

Question about the task Tetris (part 14)
Java Collections, Level 2, Lesson 15
Resolved
Confusing redrawing of the lines The logic of the algorithm is that it takes all of the non full lines and add them to an array. It leaves the full lines in the old array because the old array will be overwritten. Now, in line 25 it says add incomplete lines to the beginning of the list. This line of code doesn't make sense to me.

It technically works, but not really... I almost have it, but not quite. With the example input it works, printing 4 as the lowest and 5 as the next smallest (I have it printing both for testing) but when I added a 3 at the end of the list of numbers (but before the enter breaks the loop) and it correctly updates the lowest number to 3, b

What is happening???I don't understand what's happening, I run the code, it outputs 4, the lowest entered number. But it doesn't meet the requirements to pass, it fails the 'print the lowest entered number' and somehow it also fails 'take input from keyboard.' How is that possible if it is successfully taking in number

Is it wanting me to compare the contents or address of the strings? And what does 'pairwise' comparison mean? I assume it's a term for one of those comparison type, but this
