Coould you explain how to read the data?

Question about the task

Sokoban (part 16)

Java Collections, Level 10, Lesson 15

Under discussion

I don't know how to read the right level from a file, could you give me a hint?

All that remains is to finish implementing the level loader.
16.1. Open the levels.txt file and carefully study the file structure. The character 'X' represents a wall, ‘*’ represents a box, ‘.’ represents a storage location, ‘&’ represents a box in a storage location, and ‘@’ represents the player. There are 60 levels in the file.
16.2. Implement the GameObjects getLevel(int level) method. It must:
16.2.1. Read the data for the passed level from the file. The levels should repeat in a loop. If the user has completed all 60 levels and gets to level 61, then the program takes the user back to level 1. And instead of level 62, the player is taken to level 2, etc.
16.2.2. Create all of the game objects described in the specified level. The coordinates of each game object must be calculated using the following logic:
16.2.2.1. The top-left object (if there is one) must have coordinates x = x0 = BOARD_CELL_SIZE / 2 and y = y0 = BOARD_CELL_SIZE / 2.
16.2.2.2. An object that is one cell to the right must have coordinates x = x0 + BOARD_CELL_SIZE and y = y0.
16.2.2.3. An object that is one cell below the top-left object must have coordinates x = x0 and y = y0 + BOARD_CELL_SIZE.
16.2.2.4. The coordinates of all objects on the board must be calculated in a similar manner.
16.2.3. Create a new GameObjects object and put all of the objects into it.
16.2.4. Return the created object container.

The game must be fully functional. Check to see if there are any problems. If there are, fix them.

Requirements:

Implement the GameObjects getLevel(int level) method as outlined in the task conditions.

package com.codegym.task.task34.task3410.controller; import com.codegym.task.task34.task3410.model.Direction; import com.codegym.task.task34.task3410.model.GameObject; import com.codegym.task.task34.task3410.model.GameObjects; import com.codegym.task.task34.task3410.model.Model; import com.codegym.task.task34.task3410.view.View; public class Controller implements EventListener { private View view; private Model model; public Controller() { model = new Model(); model.restart(); model.setEventListener(this); view = new View(this); view.init(); view.setEventListener(this); } public static void main(String[] args) { Controller controller = new Controller(); } @Override public void move(Direction direction) { model.move(direction); view.update(); } @Override public void restart() { model.restart(); view.update(); } @Override public void startNextLevel() { model.startNextLevel(); view.update(); } @Override public void levelCompleted(int level) { view.completed(level); } public GameObjects getGameObjects(){ return model.getGameObjects(); } }

You have to read lines until it matches "Maze: " plus the level. Once you find a match, you go from there.
