import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;
import org.thymeleaf.templatemode.TemplateMode;
import org.thymeleaf.templateresolver.StringTemplateResolver;

public class HtmlGenerator {

    private final TemplateEngine templateEngine;

    public HtmlGenerator() {
        templateEngine = new TemplateEngine();
        StringTemplateResolver templateResolver = new StringTemplateResolver();
        templateResolver.setTemplateMode(TemplateMode.HTML);
        templateEngine.setTemplateResolver(templateResolver);
    }

    public String generateHtml(String title, String content) {
        Context context = new Context();
        context.setVariable("title", title);
        context.setVariable("content", content);
        return templateEngine.process("html", context);
    }
}

public static void main(String[] args) {
    HtmlGenerator htmlGenerator = new HtmlGenerator();
    String html = htmlGenerator.generateHtml("Hello, World!", "This is a sample HTML generated by Thymeleaf.");
    System.out.println(html);
}
