Passing CharArray to Method

I'm trying to pass my char array grid1 to the method called status. I'm receiving the error char cannot be converted to char[][]. How would I pass grid1 so it would work in the for loop?

    for (int row = 0; row < 30; row++){
        for (int col = 0; col < 30; col ++){
            if (status(grid1[row][col], row, col)){

            }
        }
    }



    public boolean status(char [][] grid, int a, int b){

    char value = grid[a][b];    
        if (value == 'X'){
            //add X to another array
            return true;
        } else {
        return false;
        }
        //add - to another array
    }

You're already dereferencing your grid1 array in the loop. So unless that loop is to be part of your status method for whatever reason, your status method could be a lot simpler: you don't need to pass a char[][], you could pass a char. And clearly you don't need the column and row indexes. Your method should be like this:

public boolean status(char value){

        if (value == 'X'){
            //add X to another array
            return true;
        } else {
        return false;
        }
        //add - to another array
}

grid1[row][col] is a single element of char array, therefore is of type char. You need to pass the whole array grid1.

the problem is that your method signature is expecting an array and you call it using a value from the array.

call like:

 status(grid1, row, col)

or fix the method signature

public boolean status(char grid){

    char value = grid;

Just replace

if (status(grid1[row][col], row, col)){

with

if (status(grid1, row, col)){
