Java zip压缩的文件 Java 解压不了。但winrar可以

Question

    public static void main(String[] args) {
        String path = "D:/a.zip";
        try {
            byte[] data = "abcd".getBytes();
            FileOutputStream os = new FileOutputStream(path);
            ZipOutputStream zos = new ZipOutputStream(os);
            ZipEntry entry = new ZipEntry("a.txt");
            zos.putNextEntry(entry);
            zos.write(data);
            zos.close();
            os.close();
            System.out.println("压缩完成");
            //
            FileInputStream is = new FileInputStream(path);
            ZipInputStream zis = new ZipInputStream(is);
            entry = zis.getNextEntry();
            String s = String.format("name=%s; size=%d", entry.getName(), entry.getSize());
            if (entry.getSize() == -1) {
                s = "解压失败:" + s;
            } else {
                s = "解压成功:" + s;
            }
            System.out.println(s);
            zis.closeEntry();
            zis.close();
            is.close();
        } catch (Throwable e) {
            throw new RuntimeException(e);
        }
    }
谁帮我看看为什么解压失败。用windows解压是可以解压出文件来的。

//
            FileInputStream is = new FileInputStream(path);
            ZipInputStream zis = new ZipInputStream(is);
            entry = zis.getNextEntry();
            byte[] buf = new byte[1024];
            int len;
            while ((len = zis.read(buf)) > 0) {
                System.out.println(new String(buf,0, len));
            }
            String s = String.format("name=%s; size=%d", entry.getName(), entry.getSize());
            if (entry.getSize() == -1) {
                s = "解压失败:" + s;
            } else {
                s = "解压成功:" + s;
            }
            System.out.println(s);
            zis.closeEntry();
            zis.close();
            is.close();
