如何在Apache POI HWPF文档中添加换行符，例如\\n

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.Paragraph;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.hwpf.usermodel.Run;

import java.io.FileOutputStream;
import java.io.IOException;

public class ApachePOIHWPFExample {
    public static void main(String[] args) {
        try {
            // 创建文档对象
            HWPFDocument document = new HWPFDocument();

            // 获取文档段落
            Range range = document.getRange();

            // 创建新段落
            Paragraph paragraph = range.insertAfter(new Paragraph());

            // 创建行对象
            Run run = paragraph.createRun();

            // 添加文本和换行符
            run.setText("Hello");
            run.addBreak();
            run.setText("World");

            // 保存文档
            FileOutputStream out = new FileOutputStream("output.doc");
            document.write(out);
            out.close();

            System.out.println("文档添加换行符成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
