This are the requirements for the lab that I need tomake:
This lab can be written entirely insidethe Maza.java file. Create a new project calledMaze.java. Then copy all of the text in Maze.java DownloadMaze.java into the file Maze.java that Netbeans created. You need 2methods:
Example text file for a maze:##### ## #####The string that should result from this file is:"####\n# ##\n #\n####"DeMorgan's Law can help you test multiple condition in one ifstatement. Here is someinformation: wikipedia.org/wiki/De_Morgan's_laws
This is the code for Maze.java
