Key Features

IronPDF for Java

IronPDF for Java is a powerful library designed to simplify PDF generation within Java applications. With IronPDF, developers can effortlessly create, manipulate, and render PDF documents programmatically, enabling the generation of dynamic reports, invoices, and documents with ease. The library offers a straightforward API for converting HTML content, including CSS styling and images, into PDF format, making it ideal for web applications and content management systems.

Here's a step-by-step guide on how to integrate these libraries:

1. Perform Mathematical Calculations: Use Apache Commons Math to perform the necessary mathematical calculations, such as solving equations, computing statistical measures, or generating charts. For example, you can use Apache Commons Math to calculate statistical measures like mean, median, and standard deviation for a dataset.
2. Generate HTML Content: Once the calculations are performed, generate HTML content representing the results. IronPDF allows you to create PDF documents from HTML content, making it easy to include dynamic data, images, and formatting in your PDF reports. You can use libraries like Thymeleaf or FreeMarker to generate HTML templates dynamically.
3. Convert HTML to PDF: Use IronPDF to convert the generated HTML content into a PDF document. IronPDF provides a simple API for converting HTML to PDF, allowing you to specify options such as page size, margins, and header/footer content.
4. Save or Stream the PDF: Finally, save the generated PDF document to a file or stream it directly to the client browser, depending on your application's requirements. IronPDF supports saving PDF documents to disk or streaming them over HTTP, making it easy to integrate PDF generation into web applications.

Example Integration

Here's an example demonstrating how to integrate Apache Commons Math with IronPDF to generate a PDF report containing statistical analysis results:

import org.apache.commons.math3.stat.descriptive.DescriptiveStatistics;
import com.ironpdf.*;
import java.io.File;
import java.io.IOException;

public class PDFReportGenerator {
    public static void main(String[] args) {
        // Perform statistical analysis using Apache Commons Math
        double[] data = {10, 20, 30, 40, 50};
        DescriptiveStatistics stats = new DescriptiveStatistics(data);
        double mean = stats.getMean();
        double stdDev = stats.getStandardDeviation();

        // Generate HTML content with statistical analysis results
        String htmlContent = "<h1>Statistical Analysis Report</h1>"
                + "<p>Mean: " + mean + "</p>"
                + "<p>Standard Deviation: " + stdDev + "</p>";

        // Convert HTML to PDF using IronPDF
        try {
            HtmlToPdfConverter converter = new HtmlToPdfConverter();
            PdfDocument pdfDocument = converter.convertHtmlString(htmlContent);

            // Save the PDF document to disk
            pdfDocument.saveAs(new File("StatisticalAnalysisReport.pdf"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

import org.apache.commons.math3.stat.descriptive.DescriptiveStatistics;
import com.ironpdf.*;
import java.io.File;
import java.io.IOException;

public class PDFReportGenerator {
    public static void main(String[] args) {
        // Perform statistical analysis using Apache Commons Math
        double[] data = {10, 20, 30, 40, 50};
        DescriptiveStatistics stats = new DescriptiveStatistics(data);
        double mean = stats.getMean();
        double stdDev = stats.getStandardDeviation();

        // Generate HTML content with statistical analysis results
        String htmlContent = "<h1>Statistical Analysis Report</h1>"
                + "<p>Mean: " + mean + "</p>"
                + "<p>Standard Deviation: " + stdDev + "</p>";

        // Convert HTML to PDF using IronPDF
        try {
            HtmlToPdfConverter converter = new HtmlToPdfConverter();
            PdfDocument pdfDocument = converter.convertHtmlString(htmlContent);

            // Save the PDF document to disk
            pdfDocument.saveAs(new File("StatisticalAnalysisReport.pdf"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
