java将英文翻译为汉字

把英文翻译为中文的Java程序可以使用第三方的翻译API，例如百度翻译API或谷歌翻译API。以下是一个简单的使用百度翻译API将英文翻译为中文的Java程序示例：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class EnglishToChineseTranslator {
    public static void main(String[] args) {
        String englishText = "Hello, world!"; // 待翻译的英文文本
        String baiduApiKey = "your_baidu_api_key"; // 百度翻译API的API Key
        String baiduApiUrl = "http://api.fanyi.baidu.com/api/trans/vip/translate"; // 百度翻译API的请求URL

        try {
            // 构造URL
            String urlStr = baiduApiUrl
                    + "?q=" + URLEncoder.encode(englishText, "UTF-8")
                    + "&from=en&to=zh"
                    + "&appid=" + baiduApiKey
                    + "&salt=" + System.currentTimeMillis()
                    + "&sign=" + MD5(baiduApiKey + englishText + System.currentTimeMillis() + "your_baidu_secret_key");
            URL url = new URL(urlStr);

            // 发送HTTP请求
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");

            // 读取响应
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            // 解析响应
            String chineseText = response.toString().split("\"dst\":\"")[1].split("\"")[0];
            System.out.println(chineseText);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static String MD5(String s) {
        // 计算MD5摘要
        // 略
    }
}
