Setter Getter Arrays Java
23,703
You are using Array of Lecture objects and overwriting the same array with two different array references. Hence, it is not working. Use the below code:
public class Student {
private Lecture[] lecture;
public void setStudentLecture(Lecture[] lecture) {
this.lecture = lecture;
}
public Lecture[] getStudentLecture() {
return lecture;
}
public static void main(String[] args) {
Student student = new Student();
Lecture[] lectures = new Lecture[3];
lectures[0] = new Lecture("Physics");
lectures[1] = new Lecture("Mathematics");
lectures[2] = new Lecture("Chemistry");
student.setStudentLecture(lectures);
Lecture[] lectures1 = student.getStudentLecture();
for (int i = 0; i <lectures1.length; ++i) {
System.out.println(lectures1[i].getName());
}
}
}
public class Lecture {
private String name;
public Lecture(String name) {
this.name = name;
}
public String getName(){
return name;
}
}
