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.

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
