A file is a place to store data we wish to persist after our program has terminated.
File handling is done using ‘pipelines’ of objects.
One cannot pass an object as a parameter to another object.
A PrintWriter object is used as a printer driver.
A buffer object holds only one character.
The println() method is only found in the standard output object.
A FileReader object is the logical representation within a program of a physical file on disk.
A file which is open for reading is closed by calling the method close() from the input buffer.
A file buffer is a means of improving efficiency when processing files.
The readLine() method is used to read data from a file.
