问题 So I have a method that looks like this: public Maze(String[] textmaze, int startRow, int startCol, int finishRow, int finishCol){ int numRows = textmaze.length; int numCols = textmaze[0].length; int [][] x = new int[numRows][numCols]; } So I want to use the variables x, numRows and numCols in other methods however numRows and numCols needs the String textmaze which must be passed in as a parameter and the main method where this method is called is in another class which I'm not allowed to
