2. Write A Byte Array To A File

Hi, In my vc++ application I'm reading some binary data from the SQL using one stored procedure.The data contains hex values stored as bytes. After reading.

I've found many ways of converting a file to a byte array and writing byte array to a file on storage. What I want is to convert java.io.File to a byte array and then convert a byte array back to a java.io.File. I don't want to write it out to storage like the following: //convert array of bytes into file FileOutputStream fileOuputStream = new FileOutputStream('C: testing2.txt'); fileOuputStream.write(bFile); fileOuputStream.close; I want to somehow do the following: File myFile = ConvertfromByteArray(bytes). I think you misunderstood what the java.io.File class really represents.

C# Write A Byte Array To A File

1. C# Append byte array to existing file. So far it is unclear what is causing your problem - all Stream and Writer classes are able to write byte arrays directly.
2. The offset parameter gives the offset of the byte in array. // Write the original file data.

It is just a representation of the file on your system, i.e. Its name, its path etc. Did you even look at the Javadoc for the java.io.File class? Have a look If you check the fields it has or the methods or constructor arguments, you immediately get the hint that all it is, is a representation of the URL/path. Oracle provides quite an extensive tutorial in their, with the latest NIO.2 functionality too. With NIO.2 you can read it in one line using. Similarly you can use to write all bytes in your byte array.

UPDATE Since the question is tagged Android, the more conventional way is to wrap the FileInputStream in a BufferedInputStream and then wrap that in a ByteArrayInputStream. That will allow you to read the contents in a byte. Similarly the counterparts to them exist for the OutputStream.
