Edit: Und eine Java-Lösung für die es sicher keine gute Punktzahl geben wird.
Month.java:
Code: Alles auswählen
package de.python_forum.blackjack.dosdate;
public enum Month {
JANUARY("January"), FEBRUARY("February"), MARCH("March"), APRIL("April"),
MAY("May"), JUNE("June"), JULY("July"), AUGUST("August"),
SEPTEMBER("September"), OCTOBER("October"), NOVEMBER("November"),
DECEMBER("December");
private final String name;
private Month(String name) {
this.name = name;
}
@Override
public String toString() {
return name;
}
}Code: Alles auswählen
package de.python_forum.blackjack.dosdate;

private final int day;

throw new IllegalArgumentException("not a valid dos date");
}
this.day = day;

return new DosDate(encoded & 0x1f, encoded >> 5 & 0xf, encoded >> 9);
}
@Override
public String toString() {
return "" + day + " " + MONTHS[month - 1] + " " + year;
}
}Code: Alles auswählen
package de.python_forum.blackjack.dosdate;
