Java I/O File Handling - Locating the Resource: File (Java IO) vs Path (Java NIO2)
In today’s video, we’re going to review together Java IO API. As you’ve already known, I/O here means input and output, more specifically, read from a resource into a java application and write from a java application out to a resource. A resource could be a disk, filesystem, network, etc,…
There are two main concepts in Java I/O:
first, we need to know where the file is and its characteristic like its name, it exists or not, it’s a folder or file,...
Second, then, we can read or write from/to this file.
