I am trying to make a program that takes the information from the main args, and displays them as a email in another class when Java is run.
Ex.
From: PersonA
To: PersonB
Email message is here
I have gotten this far, but every time I append my "email.print()" into the next class, it never can print any of the Strings.
Main Args Class:
public class TestMessage {
public static void main(String[] args) {
Message email = new Message("Harry Morgan", "Rudolf Reindeer");
email.append("Dear so and so,");
email.append("It is my great pleasure to");
email.append("write you an email.");
email.append("");
I am a first-timer using J2EE and here on coderanch.com and wanted to make a Simple Email-like System which a Registered User can Send Message/Email to another Registered User. how to do it. I have already my register/login process done but I'm stuck on how to make the Email. And I have an sample Bootstrap for my UserInterface which I want to use.
At first, oracle change this site a lot. I logged into this site after a long time and I was amazed to see the new changes. Moving onto the the question.
I am developing a spring mvc web application. The problem is when I send email, let say to more than 4 person, the program hangs for a while. Some friend told me to use thread pool to solve this. What is the general practice for handling this kind of situation?
I wrote stand alone program to post message to IBM MQ , not sure if it posted to queue i see these Another 2,102 character(s) omitted is that mean it didnt post complete message? do i have to increase capacity of text size
As a part-time student, you took two courses last term. Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.
I have a java program which would display a message dialog box. The problem is it would stopped working before even displaying the message dialog box. This is my code.
import javax.swing.JOptionPane; public class HelloDialog { public static void main(String [] args) { JOptionPane.showMessageDialog(null, "Hello World!"); } }
There is a pop-up window which would say "Java(TM) Platform SE binary has stopped working." I am using textpad. What should I do with this?
I am working my way through "Head First Java" and typing the code in the book into Notepad++ as I go. In the first few chapters the code was simple and only had one class (main). Now the code has two or more classes. Originally I would compile the code in the Command Window by typing "javac" and the program's name. After it compiled I would execute the program by typing "java -classpath . " and the program's name. However, now when program has several classes I get the following error: Could not find or load main class. Below is a program I am having issues with... does it need to be saved as two separate files?
class DogTestDrive { public static void main (String [] args) { Dog one = new Dog(); one.size = 70; Dog two = new Dog(); two.size = 8;
This is a simple project that i was using to test my current java knowledge (kinda like revision) and for that i used two classes to make a simple averaging program. i know i0m making it more difficult but like i said i'm testing myself but i come up with an unexpected error. Here's the code:
- 1st Class
import java.util.Scanner; public class Main { public static int num; public static int total = 0; public static int average;
[Code].....
Now the problem is after inputing the numbers it doesn't give me the average but the value of 0.
The requirements are as follows:Design and implement the class Day that implements the day of the week in a program. The class Day should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type Day:
A. Set the day.
B. Print the day.
C. Return the day.
D. Return the next day.
E. Return the previous day.
F. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add four days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.
G. Add the appropriate constructors.
H. Write the definitions of the methods to implement the operations for the class Day, as defined in A through G.
I. Write a program to test various operations on the class Day.Should I break down my day.java into several separate classes, one for each of the sections (previous, next, etc)?
import java.util.*; public class MyDay { static Scanner readinput = new Scanner(System.in); String day; public MyDay(String day) { day = "Sunday";
[code]....
Ideally I would like to create a Gui that would have someone type in the day, and then press a button to return the next day, prior day, or have a text input to test for adding X number of days.
At startup, the class containing your main method is loaded. It loads all classes that it needs. Each of those loaded classes loads the classes that it needs, and so on. That can take a long time for a big application, frustrating the user. You can give users of your program the illusion of a faster start with the following trick. Make sure that the class containing the main method does not explicitly refer to other classes. In it, display a splash screen. Then manually force the loading of other classes by calling Class.forName.
I'm not sure if I got this right - the tip amounts to suggesting to load all the classes altogether in the main method while displaying the splash screen?
Second, how can the main method not refer explicitly to other classes? It has to create some objects after all...
I have a problem with this ascii animation program I am working on. I declared a method inside of my class AsciiAnimation extends JFrame implements ActionListener, called
package AsciiAnimation; import java.awt.*; import java.awt.event.*; import java.util.ArrayList; import javax.swing.*; public class AsciiAnimation extends JFrame implements ActionListener{ int currentFrame = 0; ArrayList<String> frameList = new ArrayList<String>();
[Code] ....
Basically I just am trying to figure out how java works with me accessing those 2 data members, currentFrame and frameList inside of my first class ALL in the same package.
I'm trying to make a stock program that stops the user from entering in textfield and displays a message when stock is low. There's just 2 problem the entered value by the user is only decremented twice then the total stock resets for example with SofaTotal and the if statement doesn't work:
I am trying send email .So I have downloaded javaEE and javamail jar files and added buildpath.And wrote this code below .But I am getting this exception.
Exception in thread "main" java.lang.RuntimeException: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is: java.net.SocketException: Permission denied: connect at com.readAlerts.SendEmailUsingGMailSMTP.main(SendEmailUsingGMailSMTP.java:63) Caused by: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is:
[Code]...
Tried every permutation and combination but all leading to this same error.
I want to validate an email input. The email input can only have one @ and at least one '.' after the @. I would like to ask if my regex pattern is correct.
YOUR CODE HERE import java.util.InputMismatchException; import java.util.Scanner; public class email { public static void main(String []args) {
Write a program that scans a text file for possible e-mail addresses. Addresses look like this:
someone@somewhere.net
Read tokens from the input file one by one using hasNext() and next(). With the default delimiters of Scanner, an entire e-mail address will be returned as one token. Examine each token using the indexOf() method of String. If a token contains an at sign @ followed some characters later by a period, regard it as a possible e-mail address and write it to the output file.
Programs such as this scan through web pages looking for e-mail addresses that become the targets of spam. Because of this, many web pages contain disguised e-mail addresses that can't easily be automatically extracted and above that is says to modify a program from our chapter which is this:
import java.util.Scanner; import java.io.*; class NamedFileInOut { public static void main (String[] args) throws IOException { int num, square;
[Code] ....
This is the first time hasnext() and next() have been introduced to me, so whereas scan.nextInt() looks for integers, does hasNext() looks for strings or characters? the wording in the exercise text is confusing to me. so basically i should create a text file with a ton of strings and within that jumble of text, stick a few email addresses; then when the program asks the user for the input file name, use that text file's name correct? pretty sure i have it up to that point, but using the indexOf() is what i'm having trouble wrapping my head around. do i look for the index of "@" and "."? i could conceptually see how i could say if the indexOf(".") is three spaces before the end then i know it's a .com or .net or .org or whatever. but how would i use indexOf("@") when the "user name" AND the "provider" (i.e. @yahoo or @google or @whatever) have an infinite number of lengths? we haven't had literally any discussion on input/output in classes so i am totally green to this.

i found a code to get emails from gmail in this forum.It's working very well, now i want to delete a specific sender email address.
So i can have the sender email with this:
Java Code: String senderAddress = aMessage.getFrom()[0].toString(); System.out.println(" From: " + senderAddress); mh_sh_highlight_all('java'); Now i want to do something like Java Code: If (senderAddress = "test@gmail.com"){ message.setFlag(Flags.Flag.DELETED, true); } mh_sh_highlight_all('java');
I need to check the existence of email accounts before sending them mails to avoid going to a blacklist for sending to non real accounts.
I was thinking on (SSL)Sockets and smtp commands but I cant get it to work properly I am shooting in the dark here...
I have a JAVA application that sends mail to the people that buy certain things but the information quality is bad, so I must check if the mail exists before sending the mail....
