import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;

import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;

public class Document4jApp {

public static void main(String[] args) {

    File inputWord = new File("C:/Users/avijit.shaw/Desktop/testing/docx/Account Opening Prototype Details.docx");
    File outputFile = new File("Test_out.pdf");
    try  {
        InputStream docxInputStream = new FileInputStream(inputWord);
        OutputStream outputStream = new FileOutputStream(outputFile);
        IConverter converter = LocalConverter.builder().build();
        converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();
        outputStream.close();
        System.out.println("success");
    } catch (Exception e) {
