SOLUTION AT Australian Expert Writers

THIS IS IN JAVA I need help creating a 2d array from a text file. Basically, I need to read in a text file and make a 2D array from it. So in particular, if I have this file here:M 10 8S 0 2G 6 5W 4 3W 4 4W 4 5W 4 6W 5 6W 6 6W 7 6W 8 3W 8 4W 8 5W 8 6EI need it to read as followed:M 10 8 corresponds to the dimensions of the 2d array. In this case, it is a 10×8.The rest of the file goes as follows:S indicates a starting point on a map, so an S would have to be placed at 0,2 (x,y) on our 2d arrayG is the goal, so a G would be placed at 6,5 (x,y) in our 2d array.W represents walls, and a W would be placed at each corresponding x,y coordinate.E signifies the end of the file, so we can stop reading the file and close it at E.(x,y), x at 0 is the furthest left point of the 2d array while y at 0 is the top of it.What I have so far:public class AStar {/*** @param args the command line arguments*/public static void main(String[] args) {Scanner scanner = new Scanner(System.in);int x = 0;int y = 0; System.out.println(“Please enter the name of the map file: “);String filename = scanner.nextLine();try{new BufferedReader(new FileReader(filename));} catch (IOException o) {System.out.println(“There was an error opening the file.”);} String [][] map = new String[x][y]; }}I’m not sure if any of it is right thoughthanks

Using Crow;s foot Notation creat an ERD that satisfies the following •A doctor can be scheduled for many appointments, but may not have any scheduled at all.•Each appointment is scheduled with exactly 1 doctor. •A patient can schedule 1 or more appointments. •One appointment is scheduled with exactly 1 patient. •An appointment must generate exactly 1 bill, a bill is generated by only 1 appointment. •One payment is applied to exactly 1 bill, and 1 bill can be paid off over time by several payments. •A bill can be outstanding, having nothing yet paid on it at all. •One patient can make many payments, but a single payment is made by only 1 patient. •Some patients are insured by an insurance company. If they are insured, they can only carry insurance with one company. •An insurance company can have many patients carry their policies. For patients that carry insurance, the insurance company will make payments for eligible items, each single payment is made by exactly 1 insurance company.
