Lines lost during reading of a file in JTextPane

[Hunter McMillen]

Hey everyone,

I am reading java file into a JTextPane and some of the lines are getting skipped over, and I cant seem to find where, I think I just need another set of eyes to look at my read method.

/**
 * Reads a File object line by line and appends its data
 * to the JTextPane. I chose to NOT use the JTextPane's read()
 * function because it creates formatting conflicts.
 *
 * @param file      The File object to read data from
 */


    public void readFileData(File file)

  {
     Scanner fileScanner = null;

     try
     {
        fileScanner = new Scanner(file);
     }
        catch(FileNotFoundException fnfe)
        {
           System.err.println(fnfe.getMessage());
        }

     while(fileScanner.hasNextLine())
     {
        String line          = fileScanner.nextLine();
        String trimmedLine = line.trim();

            //test line for potential keywords, ignore comments
        if(!trimmedLine.contains("/**") && !trimmedLine.contains("/*") &&
           !trimmedLine.contains("//"))
        {
           boolean tst = Keywords.hasKeywords(line);
           if(tst) //keywords exist in the line, split the line up
           {
              String[] words = line.split("\\s");
              for(String word : words)
              {
                 if(Keywords.isKeyword(word))
                 {
                        //copy keyword object 
                    Keywords k = map.get(word); 
                        //append keyword with proper color
                    ui.append(k.getText() + " ", k.getColor());
                 }
                 else //not a keyword append normally
                 {
                    ui.append(word + " ", Color.BLACK);
                 }
              }
              ui.append(newline);
           }
           else //if the line had no keywords, append without splitting
           {
              ui.append(line, Color.BLACK);
              ui.append(newline);
           }
        }
        else 
        {
                //create darker color, because the built-in 
                    //orange is too bright on your eyes
           Color commentColor = Color.ORANGE.darker().darker();

            //if this is the start of a multiline comment
           if(trimmedLine.startsWith("/**") || trimmedLine.startsWith("/*") )
           {
              //while not at the end of the comment block
              while(!trimmedLine.endsWith("*/"))
              {
                 //append lines
                 ui.append(line, commentColor);
                 ui.append(newline);

                    //ensure more lines exist
                 if(fileScanner.hasNextLine())
                 {
                    line = fileScanner.nextLine();
                    trimmedLine = line.trim();
                 }
              }
                //append the ending line of the block comment, has '*/'
              ui.append(line, commentColor);
              ui.append(newline);
           }
           else if(trimmedLine.startsWith("//")) //start of single line comments
           {
              ui.append(line, commentColor);
              ui.append(newline);
           }//end if
        }//end if
     }//end while
            fileScanner.close();
  }//end readFileData()

any help would be great

Thanks,
Hunter

You have received an answer at the other forum, so why haven't you updated your posting here with the answer?

I was planning on coming back to it later on, since I am at work and have other things to be doing. I marked the topic as resolved to indicate I had found an answer, so no one would waste their time looking for one. Don't get so bent out of shape.

There is not time like the present. As soon as you accepted an answer on the other site you should have indicated that on this site. It would have taken an extra minute of your time to do this.

Why should the 5-10 people who read your question on this site first have to check with the other site to see if an answer has been found?

I will continue to get "bent out of shape" when you think that your time is more valuable than our time.

So the solution to this problem was how I was checking whether lines had comments, I was testing if a line contained comments, then only printing the line if the lines STARTED with comments, so lines like:

if(!a && !b && c) //this is a test condition

wont be printed because the line doesn't start with a comment.
