How Java uses the API of the Apache POI library to create Word files

In Java, you can use the API of the Apache POI library to create Word files. Firstly, it is necessary to add the dependencies of the Apache POI library in the project, which can be done through Maven, by adding the following dependencies in the pom.xml file: <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>4.1.2</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.1.2</version> </dependency> The above dependencies include the basic components of the Apache POI library and support for the Office Open XML format. The following is an example of creating a simple Word document using Apache POI: import org.apache.poi.xwpf.usermodel.XWPFDocument; import org.apache.poi.xwpf.usermodel.XWPFParagraph; import org.apache.poi.xwpf.usermodel.XWPFRun; import java.io.FileOutputStream; import java.io.IOException; public class CreateWordDocument { public static void main(String[] args) { //Create a new Word document XWPFDocument document = new XWPFDocument(); //Create paragraph XWPFParagraph paragraph = document.createParagraph(); //Create Text Run XWPFRun run = paragraph.createRun(); //Set Text Content run.setText("Hello World!"); try { //Save Document to File FileOutputStream out = new FileOutputStream("sample.docx"); document.write(out); out.close(); System. out. println ("Word document created successfully!"); } catch (IOException e) { e.printStackTrace(); } } } The above code creates a new Word document, then adds a paragraph and adds the text content "Hello World!" to the paragraph. Finally, save the document to the file 'sample. docx'. A Word file sample can be a specific Word document containing text, images, tables, styles, and other content. The code in the above example creates a Word file sample with only one simple paragraph content.
