解压缩（解压缩）文件显示错误，意外结束归档

Question

这里我有几个文件夹中的Bookfolder（英语，印地语，日语）。将英语，印地语，日语转换为english.zip，hindi.zip和japanese.zip。一切都很好，我把zip文件和文件夹保存在Bookfolder中，这是我用java做的事情。但是当我手动解压缩zip文件ex:english.zip时，右键单击这里的解压缩，然后显示错误为意外的归档结束。这是我的代码。

public void foldertToZip(File zipDeleteFile) {
    //System.out.println(zipDeleteFile);
    File directoryToZip = zipDeleteFile;
    List<File> fileList = new ArrayList<>();
    //System.out.println("---Getting references to all files in: " + directoryToZip.getCanonicalPath());
    getAllFiles(directoryToZip, fileList);
    //System.out.println("---Creating zip file");
    writeZipFile(directoryToZip, fileList);
    //System.out.println("---Done");
}

public static void getAllFiles(File dir, List<File> fileList) {
    try {
        File[] files = dir.listFiles();
        for (File file : files) {
            fileList.add(file);
            if (file.isDirectory()) {
                System.out.println("directory:" + file.getCanonicalPath());
                getAllFiles(file, fileList);
            } else {
                System.out.println("file:" + file.getCanonicalPath());
            }
        }
    } catch (IOException e) {
    }
}

public static void writeZipFile(File directoryToZip, List<File> fileList) {
    try {
        //try (FileOutputStream fos = new FileOutputStream(directoryToZip.getName() + ".zip"); ZipOutputStream zos = new ZipOutputStream(fos)) {
        File path = directoryToZip.getParentFile();
        File zipFile = new File(path, directoryToZip.getName() + ".zip");
        try (FileOutputStream fos = new FileOutputStream(zipFile)) {
            ZipOutputStream zos = new ZipOutputStream(fos);
            for (File file : fileList) {
                if (!file.isDirectory()) { // we only zip files, not directories
                    addToZip(directoryToZip, file,zos);
                }
            }
        }
    } catch (FileNotFoundException e) {
    } catch (IOException e) {
    }
}

public static void addToZip(File directoryToZip, File file, ZipOutputStream zos) throws FileNotFoundException,
        IOException {
    try (FileInputStream fis = new FileInputStream(file)) {
        String zipFilePath = file.getCanonicalPath().substring(directoryToZip.getCanonicalPath().length() + 1,
                file.getCanonicalPath().length());
        System.out.println("Writing '" + zipFilePath + "' to zip file");
        ZipEntry zipEntry = new ZipEntry(zipFilePath);
        zos.putNextEntry(zipEntry);
        byte[] bytes = new byte[1024];
        int length;
        while ((length = fis.read(bytes)) >= 0) {
            zos.write(bytes, 0, length);
        }
        zos.closeEntry();
    }
}`

当我提取新的zip文件（例如：english.zip）时，它显示错误为意外的归档结束（我想不是精确地压缩）‘

您需要在writezipfile()方法中关闭zipoutputstream；

for (File file : fileList) {
    if (!file.isDirectory()) { // we only zip files, not directories
        addToZip(directoryToZip, file,zos);
    }
}
//here close zos
zos.close();
