我正在尝试将字节数组转换为ZIP文件。我使用以下代码获取字节：
byte[] originalContentBytes= new Verification().readBytesFromAFile(new File(“E://file.zip”));
private byte[] readBytesFromAFile(File file) {
int start = 0;
int length = 1024;
int offset = -1;
byte[] buffer = new byte[length];
try {
//convert the file content into a byte array
FileInputStream fileInuptStream = new FileInputStream(file);
BufferedInputStream bufferedInputStream = new BufferedInputStream(
fileInuptStream);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
while ((offset = bufferedInputStream.read(buffer, start, length)) != -1) {
byteArrayOutputStream.write(buffer, start, offset);
}
bufferedInputStream.close();
byteArrayOutputStream.flush();
buffer = byteArrayOutputStream.toByteArray();
byteArrayOutputStream.close();
} catch (FileNotFoundException fileNotFoundException) {
fileNotFoundException.printStackTrace();
} catch (IOException ioException) {
ioException.printStackTrace();
}
return buffer;
}
但是我现在的问题是将字节数组转换回ZIP文件-如何完成？
注意：指定的ZIP包含两个文件。
