JAVA实现创建一个学生对象，包括学号、姓名和班级信息，利用标准化输入设置3个学生信息，并实现三个学生对象的序列化和反序列化。

以下是一个JAVA实现创建学生对象、序列化和反序列化的示例代码：

import java.io.*;

public class Student implements Serializable {
    private String studentNumber;
    private String name;
    private String className;

    public Student(String studentNumber, String name, String className) {
        this.studentNumber = studentNumber;
        this.name = name;
        this.className = className;
    }

    public String getStudentNumber() {
        return studentNumber;
    }

    public void setStudentNumber(String studentNumber) {
        this.studentNumber = studentNumber;
    }

    public String getName() {
        return name;
    }

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

    public String getClassName() {
        return className;
    }

    public void setClassName(String className) {
        this.className = className;
    }

    public static void main(String[] args) {
        Student[] students = new Student[3];

        // 从标准输入读取3个学生信息
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        try {
            for (int i = 0; i < 3; i++) {
                System.out.println("请输入第" + (i + 1) + "个学生信息：");
                System.out.print("学号：");
                String studentNumber = reader.readLine();
                System.out.print("姓名：");
                String name = reader.readLine();
                System.out.print("班级：");
                String className = reader.readLine();
                students[i] = new Student(studentNumber, name, className);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 序列化学生对象
        ObjectOutputStream oos = null;
        try {
            oos = new ObjectOutputStream(new FileOutputStream("students.dat"));
            for (int i = 0; i < 3; i++) {
                oos.writeObject(students[i]);
            }
            oos.flush();
            System.out.println("序列化学生对象成功！");
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (oos != null) {
                    oos.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        // 反序列化学生对象
        ObjectInputStream ois = null;
        try {
            ois = new ObjectInputStream(new FileInputStream("students.dat"));
            for (int i = 0; i < 3; i++) {
                Student student = (Student) ois.readObject();
                System.out.println("学生信息：学号=" + student.getStudentNumber() + ", 姓名=" + student.getName() + ", 班级=" + student.getClassName());
            }
            System.out.println("反序列化学生对象成功！");
        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        } finally {
            try {
                if (ois != null) {
                    ois.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

运行该程序，可以按照提示输入3个学生的信息，然后程序会将这些学生对象序列化到文件 `students.dat` 中，并且读取该文件，反序列化出之前序列化的学生对象，输出它们的信息。
