Skyscraper puzzle solver in Java

$begingroup$
For an assignment, I have created a solver for the Skyscraper Puzzle:
Each puzzle consists of an N×N grid with some clues along its sides. The object is to place a skyscraper in each square, with a height between 1 and N, so that no two skyscrapers in a row or column have the same number of floors. In addition, the number of visible skyscrapers, as viewed from the direction of each clue, is equal to the value of the clue. Note that higher skyscrapers block the view of lower skyscrapers located behind them.
The puzzle and the ordinances are hard coded into the program. I would like feedback on efficiency and readability. Any and all suggestions are welcome!
