Here, we are using BufferedInputStream to download a file. Then, we opened an InputStream from the file using openStream method. Next, in order to be able to download large files we wrapped the input stream into a BufferedInputStream. Also, we created a FileOutputStream by providing a path on the disk where we want the file to be saved. Next, we use a bucket of byte[] to read bytes from the input stream and writing onto the output stream iteratively.

This example, demonstrates how we can use our own buffer for example bytes so that downloading large files should not consume huge memory on our system. To do that, we have used try-with-resources block for respective streams instantiation. While writing the previous example, we had to take care of a lot of logic.
