为什么我的矢量不打印字符串？[复制]

问：

我正在研究向量，在练习一些练习时，我被困在这个特定的练习中，我的代码似乎没有打印名称字符串，我不知道为什么。在最终项目中，我只能打印平均数为 >=6 的学生姓名，因为这些姓名不会打印通过打印已批准学生的平均值而不是姓名来检查代码是否有效！ 你们能帮我解决吗？

这是主类：

package Program;

import java.util.Scanner;
import java.util.Locale;
import Entities.Student;

public class Program {

    public static void main(String[] args) {

        Locale.setDefault(Locale.US);
        Scanner sc = new Scanner(System.in);

        String name;
        double grade1;
        double grade2;
        double average;

        System.out.printf("how many students will you enter? ");
        int n = sc.nextInt();

        Student[] vect = new Student[n]; // vector that will store the students created

        for (int i = 0; i < vect.length; i++) {
            System.out.printf("imput the name, first and second grade for the student number %d%n ", i + 1);
            name = sc.nextLine(); // reads the name
            sc.nextLine();
            grade1 = sc.nextDouble();
            grade2 = sc.nextDouble();
            average = (grade1 + grade2) / 2;
            vect[i] = new Student(name, grade1, grade2, average);
        }

        for (int i = 0; i < vect.length; i++) {

            if (vect[i].getAverage() >= 6.0) {
                System.out.printf("%s%n", vect[i].getName());
                System.out.printf("%.2f%n", vect[i].getAverage());
            }
        }
    }
}

这是课程：Student

package Entities;

public class Student {
    private String name;
    private double grade1;
    private double grade2;
    private double average;

    public Student(String name, double grade1, double grade2, double average) {
        this.name = name;
        this.grade1 = grade1;
        this.grade2 = grade2;
        this.average = average;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getGrade1() {
        return grade1;
    }

    public void setGrade1(double grade1) {
        this.grade1 = grade1;
    }

    public double getGrade2() {
        return grade2;
    }

    public void setGrade2(double grade2) {
        this.grade2 = grade2;
    }

    public double getAverage() {
        return average;
    }

    public void setAverage(double average) {
        this.average = average;
    }

}
