First of all I am sorry if don't know how to explain my question properly and if the title is not fully correct or not clear enough. This is my first stackoverflow post. I will try to explain my beginner question with example:

I have following Student class:

```
public class Student {
    private String name;
    private int matrikelnummer;
    public static int STUDENT_COUNT;

    public Student(String name, int matrikelnummer){
        this.name = name;
        this.matrikelnummer = matrikelnummer;
        STUDENT_COUNT++;
    }

    public String toString() {
        return "Student Nr.: " +matrikelnummer+" Name: "+name;
    }
}

```

and another class Tutorium:

```
public class Tutorium {
    private int raumNr;
    private String tutor;
    private String fach;
    private Student[] teilnehmer;

    public Tutorium(int kapazitaet, int raumNr, String tutor, String fach) {
        this.raumNr = raumNr;
        this.tutor = tutor;
        this.fach = fach;
        teilnehmer = new Student[kapazitaet];
    }

    public String toString() {
        if (teilnehmer == null) {
            return "Noch keine Teilnehmer";
        }

        String out = "Tutorium " + fach + " Bei " + tutor + " in " + raumNr + " " + "\n";

        return out + --- ; //here i want to print all array element from teilnehmer
    }
} 

```

For e.g if have following main:

```
public class TutoriumsVerwaltung {
    public static void main(String[] args) {
        //Studenten und Tutorien erzeugen.
        Student[] studs = {new Student("Tim", 333333),
                new Student("Anna", 444444),
                new Student("Lisa", 345987),
                new Student("Karl", 336292),
                new Student("Elisabeth", 999999)};
        Tutorium[] tuts = {new Tutorium(5, 6057, "Tobias", "PPR-J"),
                new Tutorium(2, 6057, "Roland", "PPR-C"),
                new Tutorium(9, 6051, "Max", "PPR-J")};
        //Infos ueber Tutorien und Studenten ausgeben.
        System.out.println("Es gibt "+Student.STUDENT_COUNT+" Studenten.");
        for (Student student : studs)
            System.out.println(student);
        for (Tutorium tutorium : tuts)
            System.out.println(tutorium);
        System.out.println("");

```

I want toString() method from Tutorium to print in following format:

```
Tutorium PPR−J bei Tobias in Raum 6057

Teilnehmer:

Student Nr.: 333333 Name: Tim

Student Nr.: 444444 Name: Anna

Student Nr.: 345987 Name: Lisa

```

I have tried creating getters/setters (maybe not correctly?) but without success. Would someone care explaining me my problem and solution to it.
