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

好的，这个问题是可以回答的。您可以这样创建一个对象数组：

class Student {
    private String id;
    private String name;
    private int score;

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

    // getter and setter methods
}

// create an array of Student objects
Student[] students = new Student[3];
students[0] = new Student("001", "Alice", 90);
students[1] = new Student("002", "Bob", 80);
students[2] = new Student("003", "Charlie", 70);

这样就创建了一个包含三个学生对象的数组，每个学生对象包含学号、姓名和成绩三个属性。

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

创建一个对象数组，数组的元素是学生对象，学生信息包括学号姓名和成绩，求总人数和平均分

以下是一个示例代码，其中包含一个 `Student` 类来表示学生对象：

public class Student {
    private String id;
    private String name;
    private double score;

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

    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public double getScore() {
        return score;
    }
}

然后，我们可以创建一个 `Student[]` 数组来存储学生对象，然后迭代数组并计算总人数和平均分：

public static void main(String[] args) {
    Student[] students = {
            new Student("001", "张三", 80),
            new Student("002", "李四", 90),
            new Student("003", "王五", 70),
            new Student("004", "赵六", 85)
    };

    int total = students.length;
    double sum = 0;
    for (Student student : students) {
        sum += student.getScore();
    }
    double average = sum / total;

    System.out.println("总人数：" + total);
    System.out.println("平均分：" + average);
}

输出结果：

总人数：4
平均分：81.25
