public class ReadPDF {
public static final String READ_PDF = "F://knpcode//result//List.pdf";
public static void main(String[] args) {
try {
// PDFReader
PdfReader reader = new PdfReader(READ_PDF);
PdfDocument pdfDoc = new PdfDocument(reader);
// get the number of pages in PDF
int noOfPages = pdfDoc.getNumberOfPages();
System.out.println("Extracted content of PDF---- ");
for(int i = 1; i <= noOfPages; i++) {
// Extract content of each page
String contentOfPage = PdfTextExtractor.getTextFromPage(pdfDoc.getPage(i));
System.out.println(contentOfPage );
}
pdfDoc.close();
}catch (IOException e) {
System.out.println("Exception occurred " + e.getMessage());
}
}
