    That is not a compiler error. You get that error when you execute a program.
    Did you get any compiler errors? Don't try to execute the code, just compile it.
    If you don't understand my answer, don't ignore it, ask a question.

    I don't even know where the compiler is. Pretty sad.

    Ok found something. It says matrix has the value null at this spot.
    public static void printWorld(boolean[][] matrix) {
    		for (int r=0; r<matrix.length; r++) {
    			for (int c=0; c<matrix[0].length; c++) {
    				System.out.print(matrix[r][c] ? " # " : " - ");
    			}
    			System.out.println();
    		}

    I supposed you're using an IDE that hides all that.

    Next step is to fill in the new constructor. You will need read the Specifications to get the details of what arguments the constructor gets and what its supposed to do with them.

    Source of the null matrix:
    	public boolean[][] world() {
    		// TODO Auto-generated method stub
    		return null;
    	}

    The methods are skeletons. The code can't be executed yet without errors.

    Talk to whoever wrote the code in post#1 about how to rewrite it to make it fit with the new code from your professor.

    Make a list of the specifications for the constructor and work on the items one by one.

    Many of the values passed in the constructor's args are what your main() method asked for and read in from the user. Now those values are coming as args in the constructor.
