Try Catch unexpected token
提问by user673906
This code gives me an error of unexpected token on the try and catch. What is wrong?
这段代码在尝试和捕获时给了我一个意外令牌错误。怎么了？
public class WeatherTest
{
String weatherurl = "http://weather.yahooapis.com/forecastrss?w=35801&u=c";
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(weatherurl);
try {
HttpEntity httpEntity = httpClient.execute(httpGet).getEntity();
InputStream inputStream = httpEntity.getContent();
Reader in = new InputStreamReader(inputStream);
BufferedReader bufferedreader = new BufferedReader(in);
StringBuilder stringBuilder = new StringBuilder();
String stringReadLine = null;
while ((stringReadLine = bufferedreader.readLine()) != null)
{
stringBuilder.append(stringReadLine + "\n");
}
String qResult = stringBuilder.toString();
}
catch (IOException ie)
{
ie.printStackTrace();
}
}

Your try/catchblock is not inside a method.
您的try/catch块不在方法内。
You can place it in a method, and call the method.
您可以将它放在一个方法中，然后调用该方法。
public class WeatherTest {
String weatherurl = "http://weather.yahooapis.com/forecastrss?w=35801&u=c";
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(weatherurl);
public void myMethod() {
try { ... }
catch { ... }
}
}
