    Default Boolean method returning a boolean value

    I have revised the code in my previous post - actually tweaking the teacher's suggestion to fit a particular program - and now have a new problem. I get the following error (it actually prints it twice) for the following code:

    Type mismatch: cannot convert from Boolean[] to Boolean.

    public boolean check() {
    		boolean[] checkValues = new boolean[n];
    		for (int i = 0; i < n; i++)
    			checkValues[i] = true;
    		for (int x = 0; x < n; x++) {
    			for (int y = 0; y < n; y++) {
    				// Check row
    				for (int i = 0; i < n; i++) {
    					if (board[x][i] != LOCATION_EMPTY) 
    						checkValues[board[x][i]] = false;
    				// Check column
    				for (int i = 0; i < n; i++) {
    					if (board[i][y] != LOCATION_EMPTY) 
    						checkValues[board[i][y]] = false;
    			return checkValues;

    Default Re: Boolean method returning a boolean value

    checkValues is an array of booleans, not a single boolean.

    What is this code suppose to do? Without knowing that, it's difficult to help you figure out what needs to be fixed.
