Write InputStream to a file [duplicate]

Question

I have an object, in this object I have an InputStream which contains a file.

I want to write what is inside of InputStream to a file inside of a folder.

How would I go about doing this in Core Java?

I was able to print out each line of the InputStream using BufferedReader and .readLine(), however I want the entire file wrote to disk not just what is inside of it.

Hopefully this makes sense, thank you.

If you are using Java 7 or above you can use java.nio.file.Files:

InputStream in = obj.getInputStrem();
Path file = ...;
Files.copy(in, path);

It also supports different options (see CopyOption implementations like StandardCopyOption and LinkOption)
