如何在java中解码和读取chm文件？

import org.apache.tika.Tika;
import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.chm.ChmExtractor;
import org.apache.tika.sax.BodyContentHandler;
import org.xml.sax.SAXException;
import java.io.FileInputStream;
import java.io.IOException;

public class CHMReader {
    public static void main(String[] args) {
        try {
            // 创建Tika实例
            Tika tika = new Tika();

            // 创建CHM文件输入流
            FileInputStream inputstream = new FileInputStream("path/to/your/chm/file.chm");

            // 创建CHM文件解析器
            ChmExtractor extractor = new ChmExtractor();

            // 创建元数据对象
            Metadata metadata = new Metadata();

            // 创建内容处理器
            BodyContentHandler handler = new BodyContentHandler();

            // 创建解析上下文
            ParseContext context = new ParseContext();

            // 解析CHM文件内容
            extractor.parse(inputstream, handler, metadata, context);

            // 输出解析结果
            System.out.println("CHM文件内容: " + handler.toString());

            // 关闭输入流
            inputstream.close();
        } catch (IOException | TikaException | SAXException e) {
            e.printStackTrace();
        }
    }
}
