Also ich habe nun alles in der richtigen Reihenfolge, aber es kommen noch immer die gleichen Fehler.
Es kann ja auch nicht sein, dass in Eclipse die Teile unterstrichen werden, dann aber trotzdem gehen sollen.
Ich denke mal solange die unterstrichen sind, stimmt da was nicht. Leider kann ich nicht sagen was, da das für mich neu ist.
Ich habe folgende Dateien, in denen ein Fehler auftritt

Da dieses Thema für mich absolut neu ist (ich arbeite mich in das Thema gerade erst ein und habe 0Erfahrung) wäre es toll wenn mir jemand sagen könnte wo das Problem liegt.
Fehlt eine Bibliothek oder eine andere Datei oder wie kommen die Fehler zustande?
Stacktrace usw.
