If (responseCode = HttpURLConnection.HTTP_OK) This program downloads the file and saves it into the directory E:/Download. Int responseCode = httpConn.getResponseCode() HttpURLConnection httpConn = (HttpURLConnection) url.openConnection() Public static void downloadFile(String fileURL, String saveDir) Download the latest version of the cloud service API collection file from the. * saveDir path of the directory to save the file How to install and configure Postman for Zscalers cloud service API. * fileURL HTTP URL of the file to be downloaded when the user clicks on the link, it downloads a file from a server url.

Private static final int BUFFER_SIZE = 4096 * A utility that downloads a file from a URL.

Close the input stream, the output stream and the connection.įor the purpose of reusability, we create a utility class as follows: package.

Repeatedly read array of bytes from the input stream and write them to the output stream, until the input stream is empty.

Create an output stream to save file to disk.
