What delimits a "paragraph"? (That is, how can you tell the end of a paragraph?) Text processing systems like TeX/LaTex use an empty line to designate the end of a paragraph. If that's the case then, here's some pseudo-code you might consider:

Create a Scanner object with the file name. Call it infile.
(You have already done this.)
 
Declare a String. Make it empty.  (For example: String file_data = "";)
 
Repeat the following loop as long as infile has a next line:
BEGIN LOOP
 
    Declare a String called line and set it equal to infile.nextLine();
    If the length of the line String is not equal to zero
    THEN
        Set file_data equal to file_data + the line String that you just read.
    ELSE
        Break out of the Loop;
    END IF
 
END LOOP

Of course if you mean to read the entire file, and not a single blank-line-delimited paragraph, you would eliminate the IF/ELSE conditional block and just append each line. The loop terminates when there are no more lines to be read.

Some people would prefer a StringBuilder object rather than a String for file_data. You would use the StringBuilder.append() method for each line you read.


Cheers!
