Question about the task

Under discussion

three task are not passed

An object on the playing field can have one of two states: it can be alive (isAlive=true) or dead (isAlive=false).
For example, if the snake hits the edge of the playing field, it dies. The same thing happens to an apple when it is eaten by the snake. To store object state, create a boolean isAlive variable in the Apple and Snake classes. Modify the logic for drawing a snake so that dead snakes are red.

The snake can move in one of four directions. To indicate these directions, create a Direction enum with UP, RIGHT, DOWN, and LEFT fields.

And in the Snake class, create a direction field, which will store the current direction of movement. Let the snake initially move to the left. The snake's direction will be changed by the setDirection(Direction) method. Create it.

Requirements:

The Apple class must have a public boolean isAlive field that is initialized to true.
The Snake class must have a public boolean isAlive field that is initialized to true.
In the Snake class's draw(Game) method, replace all calls to the setCellValue(int, int, String) method with calls to the setCellValueEx(int, int, Color, String, Color, int) method using arguments (x, y, Color.NONE, HEAD_SIGN (or BODY_SIGN), <color of snake>, 75). If the snake is dead, its color must be Color.RED. Otherwise, any other color, for example, Color.BLACK.
There must be a public Direction enum with the following values: UP, RIGHT, DOWN, LEFT.
The Snake class must have a private Direction direction field that is initialized to Direction.LEFT when it is declared.
The Snake class must have a public setter for the direction field: setDirection(Direction), which assigns the passed value to the field.

I'd move the Direction enum in a separate file. The reason probably is, that the validator is looking for eg. Direction.LEFT when testing the code. But your inner enum needs to be addressed like Snake.Direction.Left (from outside). So it doesn't find that code.
