Java mail is there a better way to read emails?

Java mail is there a better way to read emails? - java

I have some code to read people's inbox, with a filter on send TO or FROM. The time it takes to make it process the messages is far too long.
The search term filters my total emails down to 6 emails from a specific sender, yet to process the emails it takes 4 seconds to create my email objects. I'm wondering if there is a better / faster way to do this. since I want to use this for more than just 6 emails. I'm using imaps settings with user and password to authenticate.

Russian language causing IOException

I'm making the bot for Google Dictionary using this API https://dictionaryapi.dev/. It's supposed to show word definitions in different languages. And the bot works just fine for English and Spanish. But there's an IOException every time I put in Russian words. What can be the cause of it?
Here's my Bot class.
Bot.java:
public void onUpdateReceived(Update update) {
//Model model = new Model();
WordModel wordModel = new WordModel();
Message message = update.getMessage();
if (message != null && message.hasText())
{
switch (message.getText()) {
case "/english":
DictionaryEntry.setLanguage("en");
sendMsg(message, DictionaryEntry.getLanguage());
break;
case "/russian":
DictionaryEntry.setLanguage("ru");
sendMsg(message, DictionaryEntry.getLanguage());
break;
case "/spanish":
DictionaryEntry.setLanguage("es");
sendMsg(message, DictionaryEntry.getLanguage());
break;
default:
if (!message.getText().contains("/")) {
try {
sendMsgs(message, DictionaryEntry.getWords(message.getText(), wordModel));
} catch (IOException e) {
sendMsg(message, "Не найдено");
sendMsg(message, DictionaryEntry.getUrl().toString());
}
}
break;
}
}
}
public void sendMsg(Message message, String text) {
SendMessage sendMessage = new SendMessage();
sendMessage.setChatId(message.getChatId());
sendMessage.setReplyToMessageId(message.getMessageId());
sendMessage.setText(text);
try {
//setButtons(sendMessage);
execute(sendMessage);
} catch (TelegramApiException e) {
e.printStackTrace();
}
}
public void sendMsgs(Message message, List<String> words) {
for (int i = 0; i < words.size(); i++) {
SendMessage sendMessage = new SendMessage();
sendMessage.setChatId(message.getChatId());
sendMessage.setReplyToMessageId(message.getMessageId());
sendMessage.setText(words.get(i));
try {
//setButtons(sendMessage);
execute(sendMessage);
} catch (TelegramApiException e) {
e.printStackTrace();
}
}
}
And here's my DictionaryEntry class where I process JSON string that I get from URL.
DictionaryEntry.java:
private static String language = "ru";
public static String getLanguage() {
return language;
}
public static void setLanguage(String language) {
DictionaryEntry.language = language;
}
public static URL getUrl() {
return url;
}
private static URL url;
public static List<String> getWords(String message, WordModel wordModel) throws IOException {
url = new URL("https://api.dictionaryapi.dev/api/v2/entries/"
+ DictionaryEntry.getLanguage() + "/" + message);
Scanner in = new Scanner((InputStream) url.getContent());
String result = "";
while (in.hasNext())
{
result += in.nextLine();
}
String result2 = result.replaceAll("\"", "\\\"");
List<WordModel> models = new ArrayList<>();
List<String> results = new ArrayList<>();
int count = 0;
try {
JSONArray mainArray = new JSONArray(result2);
for (int i = 0; i < mainArray.length(); i++) {
JSONObject wordEntry = mainArray.getJSONObject(i);
String wordName = wordEntry.getString("word");
wordModel.setWord(wordName);
JSONArray meaningsArray = wordEntry.getJSONArray("meanings");
for (int j = 0; j < meaningsArray.length(); j++) {
JSONObject meaningEntry = meaningsArray.getJSONObject(j);
JSONArray definitionsArray = meaningEntry.getJSONArray("definitions");
for (int k = 0; k < definitionsArray.length(); k++) {
//count++;
JSONObject definitionEntry = definitionsArray.getJSONObject(k);
String definition = definitionEntry.getString("definition");
wordModel.setDefinition(definition);
if (definitionEntry.has("example")) {
count++;
String example = definitionEntry.getString("example");
wordModel.setExample(example);
}
else {
wordModel.setExample("No examples found");
}
models.add(wordModel);
results.add("Word: " + wordModel.getWord() + "\n\n" +
"Definition: " + wordModel.getDefinition() + "\n\n" +
"Example: " + wordModel.getExample());
}
}
}
/*result = "Word: " + wordModel.getWord() + "\n\n" +
"Definition: " + wordModel.getDefinition() + "\n\n" +
"Example: " + wordModel.getExample();*/
} catch (JSONException e) {
count = 50;
}
results.add(url.toString());
return results;
}

+ URLEncoder.encode(message, "UTF-8")
You are sending a HTTP request. The URL should be appropriate for the used encoding.
There are more aspects of using the right charset/encoding, but this might already be sufficient. The site probably uses UTF-8, as that can handle the full Unicode range.
400 is BAD REQUEST.
url = new URL("https://api.dictionaryapi.dev/api/v2/entries/"
+ DictionaryEntry.getLanguage() + "/"
+ URLEncoder.encode(message, "UTF-8"));
And
Scanner in = new Scanner((InputStream) url.getContent(),
StandardCharsets.UTF_8);
StringBuilder sb = new StringBuilder();
while (in.hasNextLine())
{
sb.append(in.nextLine()).append('\n');
}
String result = sb.toString();

Check in your environment that the file was in utf-8u format Because Cyrillic may not be supported

In Workbook portion I want to read the excel file from local directory. When I run this code in debug mode, the control is going into exception block and forward it in my success page. So can some one please help me with this? I put sysout in that portion but nothing shows. I am using JXl for excel read and write. My confusion is in 3 star portion.

Not an answer, but a partial refactoring.
This is an abomination of an action. There is zero way this should have ever passed any code review:
Actions and business logic should be completely separate.
Methods should be responsible for a single responsibility. This method:
Checks content type (arguably reasonable since that's web-related)
Manually parses the form (inexcusable; use a library)
Processes an Excel file (inexcusable; extract) which in turn:
Validates against business logic
Converts Excel values to BO values
The amount of un-equivalent work the action does defies explanation. This makes it essentially impossible to reason about, debug, fix, or anything. The below is a very rough start of refactoring, but you have another day or two of work to properly isolate levels of functionality and error handling (which is wrong, by the way, because you never check vector, possibly the worst-named variable in history, for errors, it's just thrown away?!?!?!)

Error: A JNI error has occurred (javax.mail.jar)

I'm trying to read gmail messages using showmsg.java in the javamail sample package, and I keep getting this error when I run it. The program compiles fine though.
Here's the error message:

Based on your error code, check out this link:
Error: SQLSTATE[HY000]: General error: 1364 Field ‘xyz’ doesn’t have a default value
Otherwise, be sure that you're not updating a column constraint from NULL to NOT NULL if you don't provide a default value for already existing values to fill in.

J2ME , Quizz using choiceGroups

I am working on a driving licence project on j2Me wich is including Tests like quizz , well and i am having a problem after parsing the questions and moving them into choiceGroups just like that :
if (questions.length > 0) {
for (int i = 0; i < questions.length; i++) {
ChoiceGroup reponses = new ChoiceGroup("Reponses" + i, Choice.EXCLUSIVE);
reponses.append(questions[i].getReponse1(), null);
reponses.append(questions[i].getReponse2(), null);
reponses.append(questions[i].getReponse3(), null);
pass.append(questions[i].getContenu());
pass.append(reponses);
}
}
} catch (Exception e) {
System.out.println("Exception:" + e.toString());
}
disp.setCurrent(pass);
and the next step is the command who's controlling the choiceGroups to test them if they are like the true answer or not .
so i am blocked here .
if (c == valider) {
int result = 0;
for (int i = 0; i < pass.size(); i++) {
String ch = pass.get(i).getLabel();
System.out.println(ch);
}
}
I don't know how to get the choice from the choicegroup
any help

Actually, I am not sure what totally you want for:
This code will help you get selected items from choicegroup that i did long time before:
//get a selected array in choicegroup
private String[] choiceGroupSelected(ChoiceGroup cg) {
String selectedArray[] = new String[cg.size()];
int k = 0;
for (int i = 0; i < cg.size(); i++) {
if (cg.isSelected(i)) {
selectedArray[k] = cg.getString(i);
k++;
}
}
return selectedArray;
}
That function will help me get all selected items for deleting action below:
private void deleteSpecificItem() {
try {
String temp = null;
int index;
//get ChoiceGroup size
int numbers = cgTrip.size();
String selectedItems[] = choiceGroupSelected(cgTrip);
//
rs = services.RecordStoreManager.openRecordStoreByName("TripRS");
re = rs.enumerateRecords(null, null, true);
String[] tripList = new String[2];
for (int i = 0; i < numbers; i++) {
temp = selectedItems[i];
if (temp != null) {
while (re.hasNextElement()) {
try {
index = re.nextRecordId();
System.out.println("RecordID: " + index);
byte[] byteBuff = rs.getRecord(index);
String source = new String(byteBuff);
tripList = services.StringManager.getItems(source, ";", 2);
String strProcess = tripList[0] + "-" + tripList[1];
//inspect all of items in choicegroup and if they are selecting then compare with record
//If comparison is true then delete this record
if (temp.equals(strProcess)) {
System.out.println("Delete RecordID: " + index);
rs.deleteRecord(index);
re.keepUpdated(true);
break;
}
} catch (RecordStoreException ex) {
ex.printStackTrace();
}
}
}
}
try {
rs.closeRecordStore();
} catch (RecordStoreException ex) {
ex.printStackTrace();
}
rs = null;
re.destroy();
this.LoadTripItem();
} catch (RecordStoreNotOpenException ex) {
ex.printStackTrace();
}
}
