The IO classes

• The Files class' newOutputStream() method is used to create a writable file.
• A Path and a StandardOpenOption argument are passed to this method (newOutputStream[]). This method creates a file if it hasn't existed yet, opens the file for writing, and returns an OutputStream that can be used to write bytes to the file.
• The newInputStream() method of the files class is used to open a file for reading. This method accepts a Path parameter and returns a stream that can read bytes from a file.
• A BufferedReader object is declared to read a line of text from a character-input stream, buffering characters so reading is more efficient.
• The BufferedWriter class writes text to an output stream, buffering the characters.
