Textdatei mit BufferedReader einlesen

[actlyc]

Hallo,

ich habe ein Programm mit dem ich ein Array (Spielfeld) erstellen kann. Auf diesem Spielfeld kann ich eine Variable mit Konsoleneingaben wie up, down, left, right bewegen.

Nun soll das Programm, eine Map (txt.) mit BufferedReader und/oder Path.paths.get einlesen.
Der Quellcode sieht so aus (nicht mein eigener Quellcode, sondern eine Musterlösung)

// needed to use Scanner for user input

import java.util.Scanner;
import java.io.BufferedReader;
import java.io.FileReader;

                    run = false;
                    break;
                // if the user input is not one of our commands print help
                default:
                    System.out.println("Command unknown! Please type up, down, left or right to move or exit to quit this program");
            }
        } while (run);
        System.out.println("Goodbye");
    }
}

Mein Problem ist, dass ich nicht weiß wo diese Methoden eingesetzt werden und ob sie eine eigene Klasse brauchen. Habe schon viele YouTube Videos durch aber konnte nicht viel verstehen.

Bedanke mich schonmal für eure Hilfe
