I'm trying to make a 2D grid to move on. It's going to be 10x10 and that will not change. When a player clicks a square in the grid, the player gets moved to that square. How can i accomplish this?

I currently have a working board, where the player can just move to any coordinates he wants. There is no squares to stick to :-)

Just round the coordinates up to your grid size:

 1  2 `int x = xpos - (xpos % gridsize);int y = ypos - (ypos % gridsize);`

This did the trick
 1  2  3  4  5  6  7  8  9 `        Felt [][] board = new Felt[16][12];                for (int i=0; i < board.length ; i++) {            for (int j=0; j < board[i].length ; j++) {                int x = i;                int y = j;                board[i][j] = new Felt(x, y);            }        }`

Here is how I would optimize that code. I am not the most experienced so take my feedback lightly.

 1  2  3  4  5  6  7  8  9  10  11 ` // Assuming the board dimensions will never change during the game.private final byte boardWidth = 16;private final byte boardHeight = 12;      private Felt[][] board = new Felt[boardWidth][boardHeight];       for (int x = 0; x < boardWidth ; x++) {    for (int y = 0; y < boardHeight ; y++) {        board[x][y] = new Felt(x, y);    }}`

EDIT: Are you using standard Java2D, perhaps Slick2D or?
