java - (期望的标识符)getter/setter和对象

我的程序有问题。当我尝试以下编译时，我仅收到以下消息：

Tutorium.java:15: error: <identifier> expected
    public void settName(vorlesung.lectureName) {
                                              ^

所以我的代码：

Tutorium.java

public class Tutorium {
private Vorlesung vorlesung;
public String tName;
private int tNumber;


public int gettNumber() {
    return this.tNumber;
}

public String gettName() {
    return this.tName;
}

public void settName(vorlesung.lectureName) {
    this.tName = vorlesung.lectureName;
}

public String toString() {
    return (this.tName + ", " + this.tNumber);
}

public Tutorium(int tNumber){
    this.tNumber = tNumber; } }

Vorlesung.java

public class Vorlesung {
public String lectureName;
private int lectureNumber;
private int lecture;
private Dozent dozent;
private String lecturerlName;

public String getlectureName(){
    return this.lectureName;
}

public int lectureNumber(){
    return this.lectureNumber;
}

public int lecture(){
    return this.lecture;
}

public String getlecturer(){
    this.lecturerlName = dozent.lecturerlName;
    return this.lecturerlName;
}

public String toString() {
    return (this.lectureName + ", " + this.lectureNumber);
}

public Vorlesung(String lectureName, int lecture) {
    this.lectureName = lectureName;
    this.lecture = lecture +1;
    this.lectureNumber = this.lecture -1;
    this.lecturerlName = lecturerlName;
}}

我的主要方法：

public class MainVorlesung {
public static void main(String[] args) {
    Student student = new Student("STUDENTNAME", "STUDENTLASTNAME", 178, 1);
    Vorlesung vorlesung = new Vorlesung("Programmieren", 13341);
    Tutorium tutorium = new Tutorium(3);
    Dozent dozent = new Dozent("LECTURERFIRSTNAME", "LECTURERLASTNAME", 815);

    System.out.println(student.toString());
    System.out.println(vorlesung.toString());
    System.out.println(tutorium.toString());
    System.out.println(dozent.toString());

}}

我的目标是将tName的值设置为vorlesung.lectureName的值。

为什么我不能那样做呢？

感谢您的帮助。 :)
谢谢

最佳答案

由于您的目标是：


  我的目标是将tName的值设置为vorlesung.lectureName的值。


您应该完全摆脱setName方法，因为它完全取决于vorlesung字段，因此不应更改。您还应该摆脱tName字段，而将getName()更改为：

public class Tutorium {
    private Vorlesung vorlesung;
    // public String tName;  // get rid of
    private int tNumber;



    public String gettName() {
        if (vorlesung != null) {
            return vorlesung.getlecturer();
        }

        return null; // or throw exception
    }

    // *** get rid of this since you won't be setting names
    // public void settName(Vorlesung vorlesung) {
    //     this.tName = vorlesung.lectureName;
    // }

我刚刚注意到，您的Tutorium类没有并且绝对需要setVorlesung(...)方法。

public void setVorlesung(Vorlesung vorlesung) {
    this.vorlesung = vorlesung;
}
