Screenshot of the map and console after entering input

Problem description: 
The map does not show the route from the starting point to the ending point. It has no reactions after user input.

Step to reproduce: 
1. Run Main.java.
2. Enter the starting point and the destination point with appropriate integers (1 and 4 in this case) in the console.
3. Press enter.

Actual result: 
The content of the map remains unchanged. Yet, the console seems to work well. It continues prompting the users to enter another value.

Expected result: 
After entering the inputs, the map should be updated and show the route from the starting point to the endpoint using red arrows. Users can then keep entering the value and the map will keep changing.
