      private static Object f;
  
      public static void main(String args[]) {
      PDFTextStripper pdfStripper = null;
      PDDocument pdDoc = null;
      COSDocument cosDoc = null;
  
      File file = new File("D:\\1.pdf");
      try {
          f = null;
          PDFParser parser = new PDFParser((RandomAccessRead) f);
          FileInputStream f= new FileInputStream(file); 
          parser.parse();
          cosDoc = parser.getDocument();
          pdfStripper = new PDFTextStripper();
          pdDoc = new PDDocument(cosDoc);
          pdfStripper.setStartPage(1);
          pdfStripper.setEndPage(5);
          String parsedText = pdfStripper.getText(pdDoc);
          System.out.println(parsedText);
          } catch (IOException e) {
           e.printStackTrace();
         } 
        }
     }
