Question

Lab 00 Mine Counter! Objective: Write a program that creates a 10x10 multi-dimensional array, places 10 mines in random locations on the board, and finally counts the number of mines an empty space is neighboring 8 squares. For reference this works similarly to functionality in the game "Minesweeper". Then finally demonstrate that the program can create an empty board, populate it with mines, and finally count mines by using its The example above shows the center squares value is based on the number of mines "*") that surrounds its 8 neighbors. Tips and Hints: import java.util.Random; Make sure exactly 10 mines are placed in the board. If a mine already exists in that space then randomly pick another space until there are 10. This may require a loop. g each of the functionalities required into multiple methods may be extremely beneficial . A multi-dimensional array of enums, Strings, or even ints can solve this problem.

int mines = 10;
Random r = new Random();

while (mines > 0)
{
int i = r.nextInt(10); // Get random indices
int j = r.nextInt(10);
if (a[i][j] != '*')
{
a[i][j] = '*'; // Fill with mines
mines--;
}
}
System.out.println("Placing mines");
for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 10; j++)
{
System.out.print(a[i][j]);
}
System.out.println();
}
  
System.out.println("Performing mine count");
int[][] mineCount = new int[10][10];
for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 10; j++)
{
if (a[i][j] == '_') // Get all cases
{
int mine = 0;
if (i + 1 < 10 && a[i + 1][j] == '*')
mine++;
  
if (j + 1 < 10 && a[i][j + 1] == '*')
mine++;
  
if (j - 1 >= 0 && a[i][j - 1] == '*')
mine++;
  
if (i - 1 >= 0 && a[i - 1][j] == '*')
mine++;
  
if (j + 1 < 10 && i + 1 < 10 && a[i + 1][j + 1] == '*')
mine++;
  
if (j + 1 < 10 && i - 1 >= 0 && a[i - 1][j + 1] == '*')
mine++;
  
if (i + 1 < 10 && j - 1 >= 0 && a[i + 1][j - 1] == '*')
mine++;
  
if (j - 1 >= 0 && i - 1 >= 0 && a[i - 1][j - 1] == '*')
mine++;
  
a[i][j] = Integer.toString(mine).charAt(0);
}
}
}
  
for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 10; j++)
{
System.out.print(a[i][j]);
}
System.out.println();
}
}   
}

The output of above program I'm getting is:

1) It is not possible to change size of standard array
2) It is not possible for standard arrays. You can change for arrayLists.
