Java Code to Read PDF Document

Here is the code which you can use to read a file with or without tabular boundaries using the IronPDF library.

import com.ironsoftware.ironpdf.PdfDocument;
import java.io.IOException;
import java.nio.file.Paths;

/**
 * This class demonstrates how to read text from a PDF document using the IronPDF library.
 */
public class PdfReader {
    public static void main(String[] args) {
        try {
            // Load the PDF document from the specified file path
            PdfDocument pdf = PdfDocument.fromFile(Paths.get("C:\\sample.pdf"));

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

            // Print the extracted text to the console
            System.out.println(text);
        } catch (IOException e) {
            // Handle exceptions that may occur during file loading or reading.
            e.printStackTrace();
        }
    }
}

import com.ironsoftware.ironpdf.PdfDocument;
import java.io.IOException;
import java.nio.file.Paths;

/**
 * This class demonstrates how to read text from a PDF document using the IronPDF library.
 */
public class PdfReader {
    public static void main(String[] args) {
        try {
            // Load the PDF document from the specified file path
            PdfDocument pdf = PdfDocument.fromFile(Paths.get("C:\\sample.pdf"));

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

            // Print the extracted text to the console
            System.out.println(text);
        } catch (IOException e) {
            // Handle exceptions that may occur during file loading or reading.
            e.printStackTrace();
        }
    }
}

In this program, the PdfDocument class in IronPDF is used to read the contents of a PDF file. The main method creates a PdfDocument object by loading a PDF file from the specified file path "C:\sample.pdf" using the fromFile method. The extractAllText method is then called on this object to extract and return all text in the PDF as a String. The extracted text is printed to the console. The program includes error handling using try-catch blocks to manage potential IOException.
