在json文件下面，我附上了用于打开文件的代码，它会打开文件，但我仍然坚持将推文分成单个单词。
private static final String filePath = "H:\\My Documents\\OO2\\Ass\\Tweets.Json";
public static void main(String[] args) {
try {
// read the json file
FileReader reader = new FileReader(filePath);
JSONParser jsonParser = new JSONParser();
JSONObject jsonObject = (JSONObject) jsonParser.parse(reader);
// get a String from the JSON object
String Username = (String) jsonObject.get("Username");
System.out.println("The first name is: " + Username);
// get a number from the JSON object
long Name = (long) jsonObject.get("Name");
System.out.println("The accouunt name is: " + Name);
// get an array from the JSON object
JSONArray Tweet= (JSONArray) jsonObject.get("Tweet");
// take the elements of the json array
for(int i=0; i<Tweet.size(); i++){
System.out.println("The " + i + " element of the array: "+Tweet.get(i));
}
Iterator i = Tweet.iterator();
// take each value from the json array separately
while (i.hasNext()) {
JSONObject innerObj = (JSONObject) i.next();
System.out.println("Tweet "+ innerObj.get("Tweet") +
" with level " + innerObj.get("knowledge"));
}
// handle a structure into the json object
JSONObject structure = (JSONObject) jsonObject.get("job");
System.out.println("Into job structure, name: " + structure.get("name"));
} catch (FileNotFoundException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} catch (ParseException ex) {
ex.printStackTrace();
} catch (NullPointerException ex) {
ex.printStackTrace();
}
}
}
我正在尝试阅读这个Json文件并将推文消息拆分为单个单词并分析带有情绪的推文。
