Java Swing repaint(), revalidate() issue after addind Jpanel to Jpanel

i'm quite new in java and i'm trying create my own scrabble game. I created my own classes Board and Tile both JPanels. while im drawing tiles on my Board :

Tile tile = new Tile(currentlyChosenLetter, jump);
board.add(tile);
tile.setBounds(x * jump + 1, y * jump + 1, jump - 2, jump - 2);

when im doing like this everything seems working fine :

Without repaint

but after adding :

board.revalidate();
board.repaint();

tiles are misplaced, i need to repaint in case of removing Tiles.

WithRepaint

x and y im getting from my mouse position : 

int jump = board.getHeight() / 15;
int x = (e.getX() / jump);
int y = (e.getY() / jump);

where e is MouseEvent.

board.revalidate();
board.repaint();

The revalidate() statement invokes the layout manager so the child components are given a size and location based on the rules of the layout manager. The default layout manager for a JPanel is the FlowLayout so the components appear on a single line.

So don't use setBounds(...). Instead use a proper layout manager like the GridLayout and add components to each square of the grid.

I would suggestion you might want to a JLabel to each grid. Then you can add and Icon to each label with the default icon for a given square. Then as a letter is added you replace the Icon with the text.
