"Hi, Amigo! I came up with a couple of interesting tasks for you."
"They can only be completed in IntelliJ IDEA. Take a look at these interesting conditions…"
Iterating through a file tree
1. The main method is passed two arguments as inputs. The first argument is path, which is the path to the directory; the second is resultFileAbsolutePath, which is the name (full path) of an existing file that will store the result.
Find all the files
Implement the getFileTree method, which must create a list of all of the files, including nested files. Use a queue. Don't use recursion. Return a list of the paths to all the found files. Don't return paths to directories. The path must be absolute.
Advanced file search
Let's implement a configurable file search within a directory. Look over the java.nio.file.FileVisitor interface and its superclass's implementation java.nio.file.SimpleFileVisitor.
