    public class PDFBoxReadFromFile {
     
     
      public static void main(String[] args) throws Exception {
     
        try (PDDocument document = PDDocument.load(new File("C:\\Users\\ed\\Documents\\test2.pdf"))) {
     
          if (!document.isEncrypted()) {
            PDFTextStripperByArea stripper = new PDFTextStripperByArea();
            stripper.setSortByPosition(true);
            Rectangle2D rect4 = new Rectangle2D.Double(210, 160, 230, 25);
            Rectangle rect1 = new Rectangle(55, 290, 225, 17);
     
            Rectangle2D rect2 = new Rectangle2D.Double(281, 255, 255, 20);
            Rectangle2D rect3 = new Rectangle2D.Double(2, 365, 660, 1900);
            stripper.addRegion("class2", rect1);
            stripper.addRegion("class3", rect2);
            stripper.addRegion("class4", rect3);
            stripper.addRegion("class5", rect4);
            PDPage firstPage = document.getPages().get(0);
            stripper.extractRegions(firstPage);
            System.out.println(stripper.getTextForRegion("class5"));
            System.out.println(stripper.getTextForRegion("class2"));
            System.out.println(stripper.getTextForRegion("class3"));
            System.out.println(stripper.getTextForRegion("class4"));
     
            File file = new File("C:/Users/ed/eclipse-workspace/pdfboxreadfromfile/file.txt");
            FileWriter fw = new FileWriter(file);
            PrintWriter pw = new PrintWriter(fw);
            pw.println(stripper.getTextForRegion("class5"));
            pw.println(stripper.getTextForRegion("class2"));
            pw.println(stripper.getTextForRegion("class3"));
            pw.println(stripper.getTextForRegion("class4"));
            pw.close();
     
          }
        } catch (IOException e) {
          System.err.println("Exception while trying to read pdf document - " + e);

    In one line
    Use the print method instead of the println method.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    Did the print method create the desired output?

    Can you show what the output was like using the print method so we can see what the problem is?
