    Are you asking how to move the logic from the paintComponent() method to use a println()?

    Sometimes it is easier to start from the beginning than to try to rewrite code that is written for a completely different environment.

    It could take longer to rewrite a GUI app to run in a console. Your choice of course.

    change the values of an array
    Use an assignment statement:
    theArray[theIndex] = value;  // change array's contents at index element

    stock it in another
    Can you explain what that means?

    i mean that after you change the values, the program should print the new array and you should be able to keep doing this. like you are moving the cars 1 block at a time and take a picture after every move

    the program should print the new array
    The Arrays class's deepToString() method is useful for printing out the contents of a 2 dim array for debugging:
    System.out.println("an ID "+ java.util.Arrays.deepToString(theArrayName));

    If the print out is for a user to see, you'll have to write some loops and use print()

    i'm almost finished now, but when i try to get an extern file (the level) i get this error:
    --Error: File Not Found--
    The data file could not be found. Check thefile name and try again.

    where should the file be
    Where the program is looking for it to be.
    To see where the program is looking for the file, Create a File object with the same path to the file that is currently being used and print out the value of the File class's get absolute path method.

     {int[][] board = { {8,88,88,88,88,88,88,8},
                    {8,22,22,22,37,23,36,8},

    make the numbers(cars) move
    Define the rules for moving a car. If a car is at 3,4 what other locations are legal moves? There are 8 locations immediately adjacent.
    What if the other location is not empty (has a value other than 10)?

    fill the other space with '10'??
    Not sure where the "other space" is?

    If you know where the car was located before it was moved, that would be the place that is empty after the car was moved.

    -ask the player which car he wants to move
    -ask the player in which direction
    -show the gameboard where the car is moved --> so let the number move and fill the open space with 10

    the problem is that i don't know how to move the number in the array when the player calls it.
    the program asks the number and the direction but then it doesnt do anything else

    how to move the number in the array when the player calls it.
    That wasn't the step to work on. I don't see that step in the list of steps in post #44.
    Are you adding new steps to that list? If so, please post the new list of steps.

    You need to work on one step at a time. The first step was:
    -ask the player which car he wants to move

    How will the program do that?
