附加到 ObjectOutputStream（在不关闭流的情况下写入多个对象）

import java.io.*;
import java.util.ArrayList;
import java.util.List;

public class ObjectOutputStreamExample {
    public static void main(String[] args) {
        List<String> objectsToWrite = new ArrayList<>();
        objectsToWrite.add("Hello, World!");
        objectsToWrite.add("This is a test.");

        try (FileOutputStream fileOutputStream = new FileOutputStream("output.txt");
             ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream)) {
            for (String object : objectsToWrite) {
                objectOutputStream.writeObject(object);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
