sonar issue: Extract this nested try block into a separate method

java
As you can see in the below code in sonar its give the "Extract this nested try block into a separate method". I am not understand how to resolve this issue please anyone can help.

Java mail is there a better way to read emails?

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.

Image File Compression before download into path using Java

I am Downloading Image from Gmail, what the problem here is , Image file upto 6MB, So it will take some more time in order to complete its download process. So my Question is Shall i compress image while downloading(ie Before save into path)? I have looked some Image compression examples in java,but all are taking image from one path then compress and finally stores that compressed image into some other folder.
If you want code for download attachment from gmail, Please click here . Could you please help me out to find the solution?

JavaMail check message content gmail IMAP

I am trying to read my messages, I can get it to print the header but the from and the content are displayed funny.
Here is the code I am using to display the messages:
int j = message.length-1;
for (int i=j;i>=0;i--) {
System.out.println("Message " + (i + 1));
System.out.println("From : " + message[i].getFrom());
System.out.println("Subject : " + message[i].getSubject());
try {
System.out.println("Body: " + message[i].getContent());
} catch (IOException ex) {
System.out.println(ex);
}
}
The output is as follows:
Message 1:
From: [javax.mail.internet.InternetAddress;#175831e]
Subject: Hello //This is correct
Body: javax.mail.internet.MimeMultipart#15b5219
Why doesn't this print out the actual email address for the from statement? And why doesn't it print out the actual body content? (I am only interesting in the plain text.)
Whole code:
import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.search.*;
import java.util.*;
import com.sun.mail.imap.*;
import java.io.*;
public class MailClient {
public static void main(String[] args) {
try {
Properties props = new Properties();
props.put("mail.store.protocol","imaps");
Session session;
session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com","email#gmail.com","password");
IMAPFolder folder = (IMAPFolder) store.getFolder("inbox");
folder.open(Folder.READ_ONLY);
Flags seen = new Flags(Flags.Flag.SEEN);
FlagTerm unseenFlagTerm = new FlagTerm(seen,false);
Message message[] = folder.search(unseenFlagTerm);
int j = message.length-1;
for (int i=j;i>=0;i--) {
System.out.println("Message " + (i + 1));
System.out.println("From : " + message[i].getFrom());
System.out.println("Subject : " + message[i].getSubject());
try {
System.out.println("Body: " + message[i].getContent());
} catch (IOException ex) {
System.out.println(ex);
}
}
System.out.println(newMsg);
folder.close(false);
store.close();
}
catch (MessagingException e) {
System.out.println("Error: " + e);
}
}
}
Thanks!

For plain text and html messages:
String content= messages[i].getContent().toString();
For Multipart Messages:
Multipart multipart = (Multipart) messages[i].getContent();
for (int j = 0; j < multipart.getCount(); j++) {
BodyPart bodyPart = multipart.getBodyPart(j);
String disposition = bodyPart.getDisposition();
if (disposition != null && (disposition.equalsIgnoreCase("ATTACHMENT"))) { // BodyPart.ATTACHMENT doesn't work for gmail
System.out.println("Mail have some attachment");
DataHandler handler = bodyPart.getDataHandler();
System.out.println("file name : " + handler.getName());
}
else {
System.out.println("Body: "+bodyPart.getContent());
content= bodyPart.getContent().toString();
}

The JavaMail FAQ tells you how to access the main text body of a message.

change this
message[i].getFrom()
to
message[i].getFrom()[0].toString())

Try to use next:
message[i].writeTo(System.out);

read sent mails from mail server

i know how can we retrive the mails from INBOX folder...but now i want to retrieve mails from SENT ITEMS folder...i am using imap to retrieve the data...
Let me know what parameter i should pass in this function to get mails from SENT ITEMS folder
Folder folder=store.getFolder("inbox");i should change the inbox as some stirng i want to know that string...

There is not a standard name here. The IMAP spec requires that the inbox be called "INBOX", but no other folders are specifically defined. It's just a name of a folder after all - some providers will use "Sent", some will use "Sent Items" and you might even see some other variants about.
I'd recommend listing the folders that the server knows about, and selecting the appropriate one from there (either interactively, or perhaps grepping for "sent" in the name if running headless). A better option overall might be to make this a configurable parameter (if your application already has a properties file).
Of course, if this is a throwaway project you could just hard-code the value for the specific server in question. But if you want to do it properly, you'll need to be flexible.

I found the solution for my problem....
i used this code to list out the folders from mail server
and pass those values in getFolder() function...it's working fine..
Folder[] folderList = store.getDefaultFolder().list();
for (int i = 0; i < folderList.length; i++) {
System.out.println(folderList[i].getFullName());
}

Gmail stores sent mails under a folder called Sent Mail inside [Gmail] folder. So I was able to get the sent mail folder through this;
Folder sentMail = store.getFolder( "[Gmail]" ).getFolder( "Sent Mail" );

This code will retrieve all mails and will print the contents and store in local if have any attachment
