  • Einlesen einer txt.datei und speichern in einem char[][]?

    Guten Abend,

    ich benötige Hilfe beim einlesen einer Textdatei mithilfe des BufferredReaders, welches im Folgeschritt mein CharArray überschreiben soll.
    Hier mein Quellqode : :)

    Java-Quellcode

    1. // needed to use Scanner for user input
    3. import java.util.Scanner;
    4. import java.io.BufferedReader;
    5. import java.io.File;
    6. import java.io.FileReader;
    7. import java.io.IOException;
    9. /**

    11. * set.

    14. * @author John Doe 1234567 Group 42h

    16. class SokobanTesto {

    Jedoch komme ich nicht weiter, über Lösungsansätze würde ich mich freuen!
