如何将这两个课程与其他课程联系起来,以便在课程1出现“ 17-0.10”?
第1类:
public class Main {
public static int String(int room){
}
public static void main(String[] args) {
Room office = new Room(17, 0, 10);
Room lecture = new Room(2, 0, 10);
Room lab = new Room(18, 1, 1);
System.out.println(office); // => "17-0.10"
System.out.println(lecture); // => " 2-0.10"
System.out.println(lab); // => "18-1.01"
}
}
第2类:
public class Room {
public int gebaeude;
public int etage;
public int raumnummer;
public Room(int gb, int eg, int rn) {
this.gebaeude = gb;
this.etage = eg;
this.raumnummer = rn;
}
public String toString() {
return this.gebaeude + "-" + this.etage + "." + this.raumnummer;
}
}
如果您要问,我写了Class 2和“ public static int String(int room)”,这是Java的新手,我首先尝试的只是System.out.println(Room);

在您的代码中,只需删除Main类中的String()方法。其他一切都很好。
