BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

5. 網絡請求
在Android應用程序中，我們可以使用Java代碼進行網絡請求，處理服務器返回的數據。以下是一個示例代碼：
“`
public class MyAsyncTask extends AsyncTask {
protected String doInBackground(String… params) {
String result = “”;
try {
URL url = new URL(params[0]);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod(“GET”);
connection.APP開發setConnectTimeout(5000);
connection.setReadTimeout(5000);
connection.connect();
if (connection.geAPPtResponseCode() == HttpURLConnection.HTTP_OK) {
InputStream inputStream = connection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = bufferedReader.readLine()) != null) {
result += line;
}
inputStream.close();
}
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
protected void onPostExecute(String result) {
// 處理返回的數據
}
}
new MyAsyncTask().execute(url);
“`
其中，“url”是請求的URL地址。
總結
以上是一些常見的Java代碼實例。當然，這只是Java編程的入門級別，如果您想深入了解Java編程語言，需要更多的學習和實踐。希望這篇文章能給你提供一個良好的開始。
