New to Java

I cant figure out what to write for my switch statement on this assignment,
(25 spaced board game with 2 players, each taking turns rolling a die untill someone reaches 25)

my method parameters for the movePlayer method are sapposed to be which player, (player1 or player2), moves as well as how many spaces out of 6 (rolled on the die). i am also sapposed to check if a winner can be identified in case 1 and case 2.
i thought i was getting the hang of this but on this i'm at a total loss for ideas of how to do it,
anyone have suggestions?

public class GameBoard
{
        public static final int BOARD_LENGTH = 25;
	private int player1;
	private int player2;
	private int winner;
	
public GameBoard(int player1State, int player2State)
	{
		player1 = 0;
		player2 = 0;
		winner = 0;
		player1 = player1State;
		player2 = player2State;
	}
 
int player1State;
int player2State;
 
public int getBoardLength()
	{
		return BOARD_LENGTH; 
	}
 
public int getPlayer1State()
	{
		return player1State;
	}
 
public int getPlayer2State()
	{
		return player2State;
	}
 
int getWinner()
	{
		return winner;
	 }
          
public void resetBoard(int player1State, int player2State, int winner)
	     {
		player1State = 0;
		player2State = 0;
		winner = 0;
	       }
       

         // This method moves the specified player along
	// the game board a specified number of spaces.

	public void movePlayer( int spacesMoved, int playerMoved)
	{
             int spacesMoved;
             int playerMoved;

		switch( playerMoved )
		{
			case 1:
				// Your code goes here.

			case 2:
				// Your code goes here.

			default:
				System.out.println("Warning: Player " +  //Fill this in//
				                    + " does not exist!");
		}
         }
}
