有没有办法把Java序列化为TreeMap？

import java.io.*;
import java.util.TreeMap;

public class SerializationExample {

    public static void main(String[] args) {
        // 创建要序列化的Java对象
        MyObject myObject = new MyObject("Hello, World!");

        try {
            // 创建一个TreeMap对象
            TreeMap<MyObject, byte[]> serializedObjects = new TreeMap<>();

            // 将Java对象序列化为字节数组
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            ObjectOutputStream oos = new ObjectOutputStream(baos);
            oos.writeObject(myObject);
            byte[] serializedObject = baos.toByteArray();

            // 将序列化后的字节数组放入TreeMap中
            serializedObjects.put(myObject, serializedObject);

            // 打印TreeMap
            System.out.println(serializedObjects);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

class MyObject implements Serializable, Comparable<MyObject> {
    private String value;

    public MyObject(String value) {
        this.value = value;
    }

    @Override
    public int compareTo(MyObject other) {
        return this.value.compareTo(other.value);
    }

    @Override
    public String toString() {
        return value;
    }
}
