How to download a file using API for Java

Hello,

We are using API to get the Akana token which we are using the get the Access token from Box( a 3 legged authorization).

Once we get the access token how can we use the token in java code to download the file?

BoxAPIConnection boxConnection = new BoxAPIConnection(accessToken);
		boxConnection.getAccessToken();
		String fileID = "11111";
		BoxFile file = new BoxFile(boxConnection, fileID);
		BoxFile.Info info = file.getInfo();

		FileOutputStream stream;
		try 
		{
			stream = new FileOutputStream(info.getName());
			file.download(stream);
			stream.close();
		} catch (FileNotFoundException e) 
		{
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		catch (IOException e)
		{
			e.printStackTrace();
		}

When I pass the access token in constructor to create boxconnection e.g new BoxAPIConnection(accessToken);

it throws a client exception. I could not find any example which helps.
