I'm trying to make a Java Soduku solver. I have some errors in my code, any help would be great. I have some errors on cells, fields, array list, integer generate numbers, and a couple errors with brackets. Thanks for your time and help! package random; import java.util.Collections; public class Soduku { static short row; boolean check() { if(row==9) { } return true; } boolean check2() { if(cells[row[col]] != 0) { if(solve(col==8? (row+1): row, (col+1) % 9 )) { return true; } } else { Integer[] random = generateNumbers(); for(int i=0; i<9; i++) { if(!containedInRowCol(row, col, random[i] && !containedIn3x3Box(row, col, random[i]))) { cells[row] [col] = random[i]; fields[row] [col].setText(String.valueOf(random[i])); if(solve(col==8? (row +1) : row, (col +1) % 9)) return true; else { cells[row] [col] = 0; fields[row] [col].setText(""); } } } } } return false; private boolean containedIn3x3Box(int row, int col, int value) { int startRow = row/3 * 3; int startCol= col/3 *3; for(int i=startRow; i<startRow +3; i++) for(int q=startCol; q<startCol +3; q++) { if(!(i==row && q==col)) { if(cells[i] [q] ==value) { return true; } } } return false; } private Integer[] generateNumbers() { ArrayList<Integer> random = new ArrayList<Integer>(); for(int i=0; i<9; i++) random.add(i+1); Collections.shuffle(random); return random.toArray(new Integer[9]); } public static void main(String[] args) { }[/i][/i][/i][/i][/i]
