Answer 1

PDFBox is for pdf manipulation and it doesn't do OCR out of the box, you need something like ApacheTika or Tesseract OCR

if the pdf already has text in it you can extract it like this

    PDFTextStripper stripper = new PDFTextStripper();
    stripper.setStartPage(1); // 1 based
    stripper.setEndPage(1);
    String extractedText = stripper.getText(doc);
    System.out.println(extractedText);
