java - 我想写入和读取文件，当我运行 : java. io.EOFException 时出现此错误

Question

我有这个类 Dictionar ，实现了 Serialized 和类 ScriereCitire包 Controller ；

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class ScriereCitire {

    public void scriere(Dictionar dictionar){
        try (FileOutputStream fileOut = new FileOutputStream("dict.txt")){
            ObjectOutputStream objOut = new ObjectOutputStream(fileOut);
            objOut.writeObject(dictionar);
            objOut.close();
        } catch (FileNotFoundException e) {         
            e.printStackTrace();
        } catch (IOException e1) {      
            e1.printStackTrace();
        }

    }

    public Dictionar citire(){
        try(FileInputStream fileInput = new FileInputStream("dict.txt")){
            ObjectInputStream objInput = new ObjectInputStream(fileInput);
            @SuppressWarnings("unused")
            Dictionar dictionar = (Dictionar)objInput.readObject();
            objInput.close();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;

    }

}

我在项目中创建了一个名为 dict.txt 的文件。我有一个类缅因州，我称之为 GraphicInterface，它调用 ScriereCitire。但当我运行时，它指出这是一个错误:

java.io.EOFException
    at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source)
    at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source)
    at java.io.ObjectInputStream.readStreamHeader(Unknown Source)
    at java.io.ObjectInputStream.<init>(Unknown Source)
    at controler.ScriereCitire.citire(ScriereCitire.java:27)
    at view.GUI.<init>(GUI.java:46)

Answer 1

您以某种方式创建了一个空文件。可能您在创建它时遇到了异常并忽略了它。

I created a file named dict.txt in the project

如何？为什么？

注意序列化数据不是文本，不应放置在名为 .txt 的文件中。
