Я пытаюсь выяснить, почему мой код не работает, так как делаю все как в уроке и не могу найти ошибок:
Я пытаюсь отсортировать массив по avgGrade:
import java.util.*;
public class sortObjects implements Comparable {
public static void main(String[] args) {
// TODO Auto-generated method stub
class Student {
String name;
String firstName;
int examGrade;
int testGrade;
Student(String n, String fn, int e, int t) {
this.name = n;
this.firstName = fn;
this.examGrade = e;
this.testGrade = t;
}
public String toString() {
return "Student [name=" + name + ", firstName=" + firstName + ", examGrade=" + examGrade
+ ", testGrade=" + testGrade + "]";
}
float avgGrade() {
return ((this.examGrade + this.testGrade) / 2);
}
}
/* Students applying to SBWL */
var applicants = new Student[] {
new Student("Muster", "Max", 3, 1),
new Student("Thorarensen", "Sophia", 2, 4),
new Student("Blöndal", "Emma", 5, 5),
new Student("Thorarensen", "Olivia", 5, 5),
new Student("Hansen", "Ava", 1, 1),
new Student("Lovelace", "Ada", 3, 5),
new Student("Kappel", "Gerti", 4, 2)
};
System.out.println(Arrays.toString(applicants));
}
@Override
public float compareTo(Pakcage1.Student o) {
// TODO Auto-generated method stub
return this.avgGrade-o.avGrade;
}
}
