description

In this assignment, you'll write a Java program which asks the user to enter the name of a plain text file. The program reads the file and then outputs an html version according to the guidelines provided.

The purpose of the assignment is to provide some practice reading and writing files as well as reinforcing what you've learned about handling Strings

If you're unfamiliar with the basics of HTML or need a refresher, you can learn more at w3schools.

file names

The user should enter the name of an input file which ends ".txt". The output file should have the same name as the input file, except that instead of ending ".txt", it should end ".html"

the rules

We'll only be working with a very small part of HTML in this assignment. You're welcome to add more if you'd like, but at a minimum, the HTML output should begin:

<html>
<body>

and should end:

</body>
</html>

Other transformations from the input file to HTML should be done according to the following:

  • If a line begins and ends with an underscore character ('_'), the program should output the contents of that line (minus the leading and trailing underscores) within an h1 header tag. For example, if the line contained the text

    _Big Important Point_

    the program would output:

    <h1>Big Important Point</h1>

  • Blank lines are replaced with HTML paragraph tags, i.e.,

    <P>

    (You do not have to close paragraphs with an XHTML-style closing paragraph tag </P>).

  • Lines that begin with a '-' character (i.e. a minus sign) are considered to be bullet points of an unordered list.
    • In your output, lists should begin:

      <ul>

    • Each bullet point in the list will consist of the characters of the line following the '-' in the input, and will be enclosed in list item tags, i.e.,

      <li>text following the '-'</li>

    • Lists should end:

      </ul>

    So for example, if in the input file we see:

    - turkey
    - lettuce
    - tomato
    - little bit of mayo

    Your program would output

    <ul>
    <li>turkey</li>
    <li>lettuce</li>
    <li>tomato</li>
    <li>little bit of mayo</li>
    </ul>

  • Any line that doesn't match any of the previous rules will be output as is, but with a line break tag <br /> at the end.

An Example

If the input file is:

_shanty_

Who lives in a pineapple under the sea?
Spongebob Squarepants

- absorbent
- yellow
- porous

is he, Spongebob Squarepants

The program would output:

<html>
<body>
<h1>shanty</h1>
<p>
Who lives in a pineapple under the sea?<br />
Spongebob Squarepants<br />
<p>
<ul>
<li> absorbent</li>
<li> yellow</li>
<li> porous</li>
</ul>
<p> is he, Spongebob Squarepants<br />
</body>
</html>

which, when rendered in a web browser, would look something like:

shanty

Who lives in a pineapple under the sea?
Spongebob Squarepants

  • absorbent
  • yellow
  • porous

is he, Spongebob Squarepants

outputting URLs

Any text in the input file of the form [[X][Y]] should be treated as a hyperlink, where X is the URL, and Y is the text to display on the screen. For example, if X is http://www.cis.temple.edu/~jfiore/2023/fall/1068 and Y is class, your program should output a hyperlink that displays the text class, which when clicked takes the user to the page http://www.cis.temple.edu/~jfiore/2023/fall/1068.

You are not required to handle the possibility that one of these blocks begins and ends on different lines of the input file.

exceptions

Remember that you are not required to handle FileNotFoundException using try-catch-finally blocks. We'll cover these later in the semester. For now, it is only necessary to add the clause throws FileNotFoundException to each function where you write new File or any function that calls a function that has a throws FileNotFoundException clause. You'll find examples of this in our classnotes.

extra credit

For up to 5 extra credit points, define a new markup shortcut (for example, one that marks a region that should be bold or italicized, links to places in the same document, or others) and add it to your program.

For up to 5 extra credit points, write a JUnit test to test some function that you've written that is passed a string and returns a new string according to one of the transformation rules previously described.

grading

  • 2 points output html, body, </body>, </html> tags
  • 6 points reads input filename and generates correct output filename
  • 4 points recognize and output blank lines
  • 4 points recognize and output headers
  • 8 points recognize and output links
  • 8 points recognize and output lists (including <ul>, </ul>)
  • 4 points setup of input file
  • 4 points setup of output file

what to submit

Please upload your .java file to Canvas.

It's a good idea to confirm through the Canvas submission page that what you've intended to submit was uploaded. We will grade what you submit. If you submit a corrupted, empty, or otherwise incorrect file, this is what we'll grade. It is your responsibility to verify through the Canvas submission page that you've submitted the correct files and that they were uploaded properly.

Here's a Canvas tutorial on how to submit files.
