Question

I am supposed to create a Java program like this:

(Note: the bolded 4, 6, 2, 2, and n are inputs)

I also have to implement the method bodies for the following methods keeping these exact method headers :

public static int promptUser(Scanner in, String prompt, int min, int max)

public static void eraseMap(char[][] map)

public static void simplePrintMap(char[][] map)

Lastly, here's an algorithm for the main method is:

Show welcome message Begin new game loop

Call promptUser to get the width and height of the map. Create a 2 dimensional array of char for the map.
Call eraseMap to initialize the map.
Call simplePrintMap to print out the blank map.

Call promptUser for the location (row & column) to sweep.
Mark that location on the map with Config.NO_NEARBY_MINE.

Call simplePrintMap again, showing the visited location.

Continue new game loop while the user wants to keep playing.

When done playing, show the Thank you message.

Explanation / Answer

import java.io.*;

import java.util.Scanner;

public class Game{

public static int promptUser(Scanner in, String prompt, int min, int max){

System.out.print(prompt);

int inp = in.nextInt();

if(inp>max && inp<min)

promptUser(in, prompt, min, max);

else

return inp;

return inp;

}

public static void eraseMap(char[][] map){

int i,j,row=map.length,col=map[0].length;

for(i=0;i<row;i++)

for(j=0;j<col;j++)

map[i][j]='.';

}

public static void simplePrintMap(char[][] map){

System.out.println();

for(char[] row : map){

for(char val : row)

System.out.print(val + " ");

System.out.println();

}

}

public static void main(String[] args){

char resp;

Scanner in = new Scanner(System.in);

System.out.println("Welcome to Mine Sweeper!");

do{

int width = promptUser(in, "What width of map would you like (3 - 20): ", 3, 20);

int height = promptUser(in, "What height of map would you like (3 - 20): ", 3, 20);

char map[][] = new char[height][width];

eraseMap(map);

simplePrintMap(map);

int row = promptUser(in, "row: ", 1, height);

int column = promptUser(in, "column: ", 1, width);

//I don't know what do you mean by Config.NO_NEARBY_MINE, there fore I am just putting a null value there

map[row-1][column-1] = '';

simplePrintMap(map);

System.out.println("Would you like to play again (y/n)?");

resp = in.next().charAt(0);

}while(resp == 'y');

System.out.println("Thank you for playing Mine Sweeper!");

}

}
