// Import the necessary IronPDF package for working with PDF documents
import com.ironsoftware.ironpdf.PdfDocument;

import java.io.IOException;
import java.nio.file.Paths;

public class Main {
    public static void main(String[] args) throws IOException {
        // Load the PDF document from the specified file
        PdfDocument pdf = PdfDocument.fromFile(Paths.get("business plan.pdf"));

        // Extract all text from the PDF document
        String text = pdf.extractAllText();

        // Print the extracted text to the console
        System.out.println("Text extracted from the PDF: " + text);
    }
}
// Import the necessary IronPDF package for working with PDF documents
