For : the simplest goal is to keep the numeric label visible while showing snakes/ladders on top of the same cell. Building on 's suggestion to use images, two practical, maintainable approaches work well in Swing: (A) keep one component per cell (JLabel with both text and icon), or (B) render the whole board in a custom JPanel and draw snakes/ladders programmatically. Both approaches avoid losing the numbers; choice depends on needed visual complexity and resize behavior.

Approach A — JLabel per cell (quick, component-based): use a transparent PNG for the snake/ladder image and set it as the JLabel icon while keeping the label text centered. Scale icons to cell size so the image does not obscure the text layout. Example setup:

ImageIcon icon = new ImageIcon(originalImage.getScaledInstance(cellWidth, cellHeight, Image.SCALE_SMOOTH));
JLabel cell = new JLabel("25", SwingConstants.CENTER);
cell.setIcon(icon);
cell.setHorizontalTextPosition(SwingConstants.CENTER);
cell.setVerticalTextPosition(SwingConstants.CENTER);
cell.setForeground(Color.BLACK);
cell.setOpaque(true);

Tips: use contrasting text color, set borders for visual separation, and pre-scale images to avoid runtime stretching artefacts.

Approach B — custom painting (best for smooth snakes, curves, and full control): override paintComponent and draw grid numbers, then draw snakes/ladders as anti-aliased paths. Maintain a simple model like an int[] jumps where jumps[src] = dst. Mapping a square number to pixel coordinates in a zigzag board:

int idx = n - 1;
int rFromBottom = idx / cols;
int cInRow = idx % cols;
int col = (rFromBottom % 2 == 0) ? cInRow : (cols - 1 - cInRow);
int row = rows - 1 - rFromBottom;
int x = col * cellWidth + cellWidth/2;
int y = row * cellHeight + cellHeight/2;

Extra notes: JLayeredPane can combine both methods if components and painted layers are required. Always separate board model (numbers, jumps) from rendering, test with debug outlines, and prefer vector drawing for smooth scaling.

Use images?
Can you explain what you have now and how you want to change it?

Sir, I jus developed in grid layout with 50 labels. If I use image on it means the numbers will vanish know sir. I dono whether my idea is correct or not. Please suggest me.

I don't know about the game you are trying to make or what its grid should look like. If you need numbers in all the squares of a grid then you could use JLabels and set their text to numbers.
