i have wrote most of my sudoku code including the gui. i need help flickering two colors for a solved row, col, or 3*3 box. i have a writeNumber method that will probably make the new method easier(it takes the logical x/y coordinates and translate them into phyiscal coordinates.). i am very new to the timer class and i know i need it for this feature. i also think i need another method to detect a row,col, or the box being solve.



Here is the writeNumber method:
private void writeNumber(Graphics g, byte x, byte y, String number, Color color)
{

final int factor = 40;

g.setFont(new Font("Serif", Font.BOLD, 30));
g.setColor(color);

if (!number.equals(""))
{

byte temp = Byte.parseByte(number);

g.drawString(String.valueOf(temp), 12 + x * factor, 30 + y * factor);
}
}
