I’m a newbie to java
. Can anyone pls help me with resolving the error arrayindexoutofboundsexception
.
public class Minesweeper { public static void main(String[] args) { int M = Integer.parseInt(args[0]); int N = Integer.parseInt(args[1]); double p = Double.parseDouble(args[2]); // game grid is [1..M][1..N], border is used to handle boundary cases boolean[][] bombs = new boolean[M+2][N+2]; for (int i = 1; i <= M; i++) for (int j = 1; j <= N; j++) bombs[i][j] = (Math.random() < p); // print game for (int i = 1; i <= M; i++) { for (int j = 1; j <= N; j++) if (bombs[i][j]) System.out.print("* "); else System.out.print(". "); System.out.println(); } // sol[i][j] = # bombs adjacent to cell (i, j) int[][] sol = new int[M+2][N+2]; for (int i = 1; i <= M; i++) for (int j = 1; j <= N; j++) // (ii, jj) indexes neighboring cells for (int ii = i - 1; ii <= i + 1; ii++) for (int jj = j - 1; jj <= j + 1; jj++) if (bombs[ii][jj]) sol[i][j]++; // print solution System.out.println(); for (int i = 1; i <= M; i++) { for (int j = 1; j <= N; j++) if (bombs[i][j]) System.out.print("* "); else System.out.print(sol[i][j] + " "); System.out.println(); } } }
and here is the exception:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0 at Minesweeper.main(M
