创建一个对象数组,数组的元素是学生对象，学生的信息包括学号，姓名和成绩

以下是一个示例代码，创建一个包含三个学生对象的数组：

class Student {
    private int id;
    private String name;
    private double grade;

    public Student(int id, String name, double grade) {
        this.id = id;
        this.name = name;
        this.grade = grade;
    }

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public double getGrade() {
        return grade;
    }
}

public class Main {
    public static void main(String[] args) {
        Student[] students = new Student[3];
        students[0] = new Student(1, "Tom", 89.5);
        students[1] = new Student(2, "Jerry", 78.0);
        students[2] = new Student(3, "Alice", 92.5);

        for (int i = 0; i < students.length; i++) {
            System.out.println("Student " + students[i].getId() + ": " + students[i].getName() + " - Grade: " + students[i].getGrade());
        }
    }
}

输出结果：

Student 1: Tom - Grade: 89.5
Student 2: Jerry - Grade: 78.0
Student 3: Alice - Grade: 92.5
