学生对象的HashMap不打印Student的对象

Question

import java.util.Scanner;

public class StudentMap extends Student{
    public static void main(String[] args)
    {
        Student[] studentClass = new Student[2];
        Scanner s1 = new Scanner(System.in);
        for(int i=1;i<=studentClass.length;i++)
        {
            System.out.println("Enter name for "+i+"Student");
            String studentName = s1.next();
            System.out.println("Enter email for "+i+"Student");
            String email = s1.next();
            System.out.println("Enter phone number for "+i+"Student");
            Integer num = s1.nextInt();
            studentClass[i] = new Student();
            studentClass[i].setName(studentName);
            studentClass[i].setEmail(email);
            studentClass[i].setPhoneNumber(num);
        }
        s1.close();
        for(Student stu : studentClass)
        {
            System.out.println(stu.name);
            System.out.println(stu.email);
            System.out.println(stu.phoneNumber);
        }
    }
}

执行此代码时，它会出现OutOfBoundIndex错误。 我已创建了Student类，其中包含name，email和phoneNumber的所有set方法。
