I'm doing a "game" for a school project and I fall in a problem. I have 4 pawn (player) and I must to move them from the value of a dice roll in a snake circuit.
Where must I put the player movement and how can i link it with the dice?

Move pawn (player) from dice roll
That would be game control, which belongs in your subclass of World. You can have a method in the class of the player to receive the number to move that is called by the world after the dice is "rolled". That method should perform the appropriate movement for the player.
I fall in a little problem. We must to make the game of the goose :/
the problem is that in the movement i must to add the pattern of the "road". (image of the board: 
) . the problem that i have now is when i have added the "snake road".
to make things easier i'll add my code :D
the world class:
my player class:
and finally my dice class:
thank you in advance for your help

You can programmatically create the pattern of the road using the position of the player. The following should show what I mean:
If player is at left or right edge, then getX()%8 will result in a value of zero.
TEST:
getX() = 0 or 8 : result 0
getX() = 1, 2, 3, 4, 5, 6 or 7 : result is 1, 2, 3, 4, 5, 6 or 7
When at left or right edge, if map goes up, then getY()%2 + (getX()%9)/8 will result in a value of one.
TEST:
getX() = 0, getY() = 1, 3, 5 or 7 : result (1 + 0) = 1
getX() = 0, getY() = 0, 2, 4 or 6 : result (0 + 0) = 0 (cannot move up)
getX() = 8, getY() = 0, 2, 4 or 6 : result (0 + 1) = 1
getX() = 8, getY() = 1, 3, 5 or 7 : result (1 + 1) = 2 (cannot move up)
If cannot move up then player moves right only when getY()%2 results in a value of 0.
TEST:
getY() = 0, 2, 4, or 6 : result 0 (move right)
getY() = 1, 3, or 5 : result 1 (move left)
So, if at edge and can move up, move up; else move horizontally:
public void moveOneSpace()
{
if (getX()%8 == 0 && getY()%2+(getX()%9)/8 == 1) setLocation(getX(), getY()-1);
else setLocation(getX()+1-2*(getY()%2), getY());
