Randomly generated rows and columns in Array

Randomly generated rows and columns in array:
Im coding a program for a game of chess. The code isn't complete but...I'm having a problem in the constructor. Im trying to to assign Q to an element in the array with a randomly generated row and column and i receive a loss of precision error.....

Code:

public class DancingQueen
{
    public static int BOARD_SIZE = 8;
    public static char SPACE = ' ';
    private char [][] board;
    
    public DancingQueen()
    {
       board = new char [BOARD_SIZE][BOARD_SIZE];
       //nested for loop
       for (int row =0; row< board.length; row++)
            for(int col =0; col<board.length; col++)
            {
                SPACE = board[row][col];
            }

         (ERROR COMES HERE) board(int)[(Math.random()*BOARD_SIZE)](int)[(Math.random()*BOARD_SIZE)] = 'Q' ;
          int x = (int)'Q';
        }
       
      
    
    
    public char[][] getBoard()
    {
        char[][] temp = new char[board.length][board[0].length];
        for(int row = 0; row < board.length; row++)
            for(int col = 0; col < board[0].length; col++)
                temp[row][col] = board[row][col];
        return temp;
    }
  


    public String move(int fromRow, int fromCol, int toRow, int toCol)
    {
        if(fromRow<0 || fromRow>7 || fromCol<0 || fromCol>7){
            System.out.println("Invalid from coordinate.");}
        if(toRow<0 || toRow>7 || toCol<0 || toCol>7){
            System.out.println("Invalid to coordinate.");}
            
            
        
        //moves vertical, horizontal,diagnol
        //||of fromCol to toCol = || fromRo to toRow
    }
       

    }
