怎么用java实现html代码

ava要运行html代码，需要运行在服务器端，也就是servlet容器中，经过容器编译解析，返回html静态内容，示例如下：

在servlet里面写就可以了

引入一系列包

import java.io.IOException

import java.io.PrintWriter

import javax.servlet.ServletException

import javax.servlet.ServletRequest

import javax.servlet.ServletResponse

import javax.servlet.http.HttpServlet

import javax.servlet.http.HttpServletRequest

import javax.servlet.http.HttpServletResponse

import java.io.*

public class Servlet1 extends HttpServlet {

public void doGet(ServletRequest req,ServletResponse res)throws ServletException, IOException{try{PrintWriter pw=res.getWriter()//在浏览器输出需要

pw.println("<script<script")}catch(exception e){="" e.printstacktrace()="" 为发现调试错误}}}=""

如下：

public static String do_post(String url, List<NameValuePair> name_value_pair) throws IOException {

        String body = "{}"

        DefaultHttpClient httpclient = new DefaultHttpClient()

        try {

            HttpPost httpost = new HttpPost(url)

            httpost.setEntity(new UrlEncodedFormEntity(name_value_pair, StandardCharsets.UTF_8))

            HttpResponse response = httpclient.execute(httpost)

            HttpEntity entity = response.getEntity()

            body = EntityUtils.toString(entity)

        } finally {

            httpclient.getConnectionManager().shutdown()

        }

        return body

    }

    public static String do_get(String url) throws ClientProtocolException, IOException {

        String body = "{}"

        DefaultHttpClient httpclient = new DefaultHttpClient()

        try {

            HttpGet httpget = new HttpGet(url)

            HttpResponse response = httpclient.execute(httpget)

            HttpEntity entity = response.getEntity()

            body = EntityUtils.toString(entity)

        } finally {

            httpclient.getConnectionManager().shutdown()

        }

        return body

    }

。。写个简单的，给个思路吧。。

public class FileTestDemo {

public static void main(String[] args) {

File file = new File("E:\\test.html")

OutputStream out = null

try {

out = new FileOutputStream(file)

out.write("<h1>test2</h1>".getBytes())

out.flush()

} catch (Exception e) {

}

}

}

要用到OutputStream输出流，可以看一下API。。
