![]() In the UML diagram, you will see class names in the form package::class. It is visible only within its own package.įurthermore, we use packages to better organize our code. This occurs when an attribute has no visibility modifier (i.e., no public, private, protected). The one example in the diagram is ToggleButtonEventHandler, which has a field of type NonogramMakerPresenter.Ī tilde (~) indicates package-private visibility. The class touching the back of the arrow has a field whose type is the class that touches the arrowhead. The class touching the back of the arrow has a method parameter or local variable (but not a field) whose type is the class that touches the arrowhead.įor instance, the start() method in the Main class has a local variable of type NonogramMakerPresenter, so the diagram has a dashed, open arrow pointing from Main to NonogramMakerPresenter.Ī solid line with an open arrowhead indicates an association. The diagram includes three symbols that have not appeared in earlier assignments:Ī dashed line with an open arrowhead indicates a dependency. ![]() The nonogram maker consists of the classes shown in the UML diagram below. The text files for both examples can be found in the puzzles directory of this repository The remaining lines represent the rows and columns of the cell grid where 0s represent empty cells and 1s represent filled cells.īelow is a second example recreating the OU logo. Similarly, the final C lines contain the nonogram numbers for the columns in order from left to right with one column per line. The next R lines contain the nonogram numbers for the rows in order from top to bottom with one row per line. The first line contains the dimensions of the cell grid: the number of rows R followed by the number of columns C. This program runs using command line arguments specifying the number of rows, number of columns, and cell length (i.e., the size of a square). See the document javafx.md for instructions on how to do this. To use the library, we need to download and manually add it to the build path. The graphical interface of the nonogram maker will be created with JavaFX. The program will take this image and calculate the row and column numbers of the corresponding nonogram. The program will have a graphical interface that allows a user to draw a binary image. In this example, the image is a boring letter P, but puzzles can be generated from any two-color pixel art.įor Project 4, we will write a nonogram puzzle maker. The solution to the puzzle is shown below, and it illustrates the feature of nonograms that is responsible for their popularity: Solving the puzzle reveals a hidden binary image! The pair of 2s that labels the fourth row indicates that there are two contiguous groups of 2 filled cells, and the groups are separated by one or more empty cells. The 4 that labels the second row indicates that 4 of the 8 cells are filled, and there are no empty cells between any pair of filled cells (i.e., the filled cells are in a single contiguous group). The 0 that labels the first row indicates that none of the cells are filled. The cells are initially empty, and the goal is to fill the correct cells to satisfy the numbers. ![]() Specifically, the numbers are the lengths of the contiguous groups of filled cells in the row or column. The cells can be in two states, empty or filled, and the numbers indicate which cells are filled. Over the past decade, they've become increasingly popular in video game form, where they are more commonly known by Nintendo's trademarked name, "Picross" (a portmanteau of "picture" and "crossword").Ī nonogram consists of a grid of cells in which each row and each column are labeled by a list of numbers. Nonograms are grid-based logic puzzles invented independently by Non Ishida and Tetsuya Nishio in 1987. Hoare (British computer scientist, winner of the 1980 Turing Award) Make it so complicated that there are no obvious deficiencies. So simple that there are obviously no deficiencies, and the other way is to There are two ways of constructing a software design: One way is to make it ORIGINAL OWNER IS THE UNIVERSITY OF OKLAHOMA CS 2334 Project 4: A Simple Nonogram Maker THIS IS A COLLEGE PROJECT AND NOT MY OWN, THIS IS HERE TO SHOW WHAT I WAS ABLE TO DO WHEN COMPLETING THIS PROJECT.
