BufferedReader - Read Names Off Of Email Addresses In A Text File And Print To Console
Nov 5, 2014I'm trying to write a program to read the names off of email addresses in a text file and my code is not printing anything to the console. So I want to print everything before the "@" sign. It seems like I'm missing a big thing
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;

Getting File Size Of Email Attachment?
Jun 17, 2014how to get the file size of an email attachment.
I used the following code to get this information.
l_EndUserObj.attachmentSize = mailAttachments.length();
The output is constant 2 even though the file size for each email attachment differ.
When I tried to use the getsize() I'm just getting an error that it is not a function.
I'm using BPM Studio during my coding.
Scanning Text File For Email Addresses
Mar 2, 2014Write 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.
Read Text File Into Object Array And Creating Random Access File
Dec 8, 2014I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.
Here is the base Product class that must be used to create the objects for the array.
public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;
[Code] .....
And then here is the data from the text file that i must extract to use to create product objects.
Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19
These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....
Read Text File Into Array Ask User To Save File And Print Data
Jul 14, 2014New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.

Read Input File And Create Output With Anagram For Words In File
Sep 24, 2014Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!
Heres is the code:
import java.io.*;
import java.lang.*;
import java.util.*;
/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.

How To Set Delimiters For Email That Is Saved As A Text File In Java
Jul 23, 2014I have saved emails that are stored in to text files and I want to retrieve the Sender, Reciever, Subject and the Email Content.I am using From: as a delimiter and To: as a delimiter and Subject as a delimiter and I am not sure what delimiter I should set for the email content.Also, there can be emails that will have comments after the message content and I plan on using the delimiter Comments:.
Any example of what delimiters I should use it would be great. Also I would like to know how check whether or not a delimiter exists so that I can print out the comments if it exists and if the file does not have comments, it prints out nothing.

Read File And Input Each Line Of File Into Array
Mar 21, 2015I am trying to read a file and input each line of the file into an array. I have not set the array size as I was hoping to fill the array using a while loop. Unfortunately the scope of the array does to work inside the while loop so I am being told that the array 'students' has not been initialised even though it has just outside of the while loop. Is it possible to do what I am trying to without having the array initialised in the while loop as surely the array will be reset every time if it was in the while loop? Here is my code:
public static void students(String file) throws FileNotFoundException {
try {
File studentInfo = new File(file);

Can't Read From A File
Apr 12, 2015I am writing a program that needs to read from a file, but I can't even get it to open. I have tried saving the .txt file 2 different ways. First, I saved the file to my src/package folder. Then I tried just the src folder. Then I tried going through Import/general/filesystem/ and selecting the root directory. However, my program is still unable to open the file.
private void readFile(String filename){
Scanner file;
try {
file = new Scanner(new File(filename));
System.out.println(file);
file.close();
} catch (Exception e){
System.out.println("Could not find file");
}
}
What am I doing wrong? How/where should I put the file?

Unable To Read File
Nov 27, 2014You are given a text. Write a program which outputs its lines according to the following rules:
If line length is ≤ 55 characters, print it without any changes.
If the line length is > 55 characters, change it as follows:
Trim the line to 40 characters.
If there are spaces in the resulting string, trim it once again to the last space (the space should be trimmed too).
Add a string... <Read More> to the end of the resulting string and print it.
I felt as if I did do what they were asking, but for some reason, I'm getting "Sorry, Unable to read file!"."Instead of using file, I did use the location of the file name".Also, I've attached a image of the input looks like and the output.

View Replies View RelatedUse TextIO Methods To Read File
Dec 2, 2014For the unit 3 assignment, you must develop a program. that reads the file icecream.dat. This file is supplied in the Files for Unit 3 Assignment directory in Unit 3. You must use TextIO methods to read the file. As you read the file, count the total number of ice cream cones that were sold. (This is the same as the number of lines that you read from the file.) Also count the total number of "Strawberry" cones that were sold.
At the end of the program, print out the total number of cones, the number of Strawberry cones, and the percentage of cones that were Strawberry.To do this program, you have to know when to stop reading from the file. TextIO has a function named TextIO.eof() to check whether the entire file has been read. The value of this function is true if the entire file has been read. The value is false if there is more data in the file. You want to continue reading from the file as long as TextIO.eof() is false.
Note: Suppose that flavor is a variable of type String and you want to test whether its value is "Strawberry". To do this, test whether flavor.equals("Strawberry"). (Do not use == to test for equality of Strings.)
Each line of the file icecream.dat is an ice cream flavor such as "Vanilla" or "Strawberry." A line represents the sale of one ice cream cone of the given flavor.
You must complete your program, test, debug, and execute it. You must submit your java code file. The output of your program must be captured by either copying the content in the output window and pasting it into a text document that you submit along with your java code file, or by capturing the image of the screen which contains the output of your java program. In windows you can capture a screen shot with the Ctrl Alt and Print Screen key sequence. This image can then be pasted into a Word, WordPad, or OpenOffice document which can be submitted with your assignment.
For students using the programr service online. Make sure that you create both the TextIO.java and the icecream.dat files as java project files. I found it was easier to rename icecream.dat to icecream.txt for some reason. For students using Netbeans, use the same set of rules that were defined in Unit 2 to setup your project and incude the TextIO.java file as we did in unit 2. Also make sure that you copy the icecream.dat file into your project directory so that it can be found by your java program.

Read And Process File Using Thread?
Nov 4, 2014I created a main class called X and two Y and Z classes.
Y and Z implements Runnable classes.
class X contains a static array A that can be accessed in Y and Z.
The Run () method of the class Y reads an input file and populates the vector A.
The Run () method of the Z class uses data stored into the vector A to process some data.
The objective of using threads in this problem is: as the vector A is filled in the Run () method of class Y, the Run () method of the class Z will processing the received values in the vector A.
to do this I did the following calls in the main method of class X:
ObjectY y = new Y ();
Thready thread = new Thread (objectY);
threadY.start ();
ObjectZ new Z = Z ();
Threadz thread = new Thread (objectZ);
threadZ.start ();
is that correct? I'm getting the expected results, but dont know if the code is parallelized in fact.
