Assigning a value to a variable from a .txt file

Hello, I'm having a slight problem doing this.
I have a text file called text.txt, and within it is the text "one two" (minus the speechmarks).
I'm simply trying to assign the second one of these words, (i.e. "two"), to a string variable of mine called second.
import java.util.*;
import java.io.*;
public class Class
    public static void main() throws FileNotFoundException
        FileReader file = new FileReader("C:\\Documents and Settings\\Admin\\Desktop\\numbers.txt");
        Scanner scanner1 = new Scanner(file);
String first = scanner1.next();
//String second =   // this is the part I don't know.
System.out.println(first); //this works fine, and shows "one"
System.out.println(second) // this is what I'm trying to make work, by showing "two".
}I hope I've explained myself clearly.
Thanks a lot, I'm really struggling with this seeminly-simple problem.

The Scanner API has good examples of how to use the class's methods. Try
String second =scanner1.next();And change the name of your class from "Class" to something else. Java uses that name for one of its classes.

How to load variables from a .txt file

Hi.
I usually make a flash aplication in colaboration with a php
programmer. But i want to test my swfs without having to wait for
him. So i want to do that through a text file. I know that flash
can load variables from text files. The problem is i don't know how
to format the text file ( example.txt).
Thank you

Here's a couple of ideas.
First you probably want to change what you have...and put
your 'if (pVar==1' etc inside a separate function and call it from
the onLoad handler after you have assigned the value to pVar...
because the onLoad will run at some unknown point in time after
loading has finished (actually in the test environment this might
work... but that wouldn't be the same as what happens in a
production setting).
To create test files for loadvars... simply create a new as2
file and put this code on the first frame and test movie:

Assign numeric value to a variable from an item

Someone please help me. I am attempting to assign a variable a numerical value from a text field. For example,
my text field item is :P202_AMOUNT. How do I assign the number that is entered into this item to a PLS_INTEGER variable? I have attempted to uss this line of code but it hasn't worked:
v_amount PLS_INTEGER := :P202_AMOUNT;
Please help.
-Stefano

Stefano,
The code you showed will work in the declaration section of a PL/SQL block that is part of your application's metadata (region, process, computation, etc.). Perhaps you are attempting to compile such a block externally using the bind variable. If that is the case, try v('P202_AMOUNT') instead. Or maybe your question is about format masks... How about giving us a bit more to go on?

Assign value to ODI variable from Jython

Hello Experts,
I have a procedure where I'm using Jython code. I want to assign a value to an ODI project variable from a Jython function:
Example:
#COUNTER = len(v_jythonList) ---> being #COUNTER the ODI project variable and len() the jython function
Now, i noticed that using ODI variables adds # sign which is use for comments in Jython code. Is there a way to assign values to ODI variables from Jython script?

How to define and populate value to a variable in a text file

hi all,
i have a text file on unix server, when i read it through open dataset, is it possible to populate dynamic value to a variable in the text file. and is it possible to define a variable at any place in the text file?
after this the program will send the internal table for emailing.
thanks.

Hi, If this file on server is a email template you can put some tags / marks and you can change it after you read it with OPEN DATASET / READ...
Sample:
OPEN DATASET p_file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
CHECK sy-subrc EQ 0.
DO.
READ DATASET p_file INTO lv_string.
IF sy-subrc EQ 0.
EXIT.
ENDIF.
REPLACE ALL OCCURENCES OF '((SYSTEM_ID))' WITH sy-sysid.
APPEND input_file_tab.
ENDDO.
CLOSE DATASET p_file.
on file there's a line with:
This email was generated on server ((SYSTEM_ID))
It will be translated to (sy-sysid = DEV):
This email was generated on server DEV
This is a "variable" like that you can use.

Loading text from a .txt file

I want to do something that should be VERY simple, but due to
Adobe's insistence on using #$%^ing tutorials instead of just
providing step by step instructions, it's very frustrating to
figure out how to do it.
All I want to do is load the contents of a text file into a
dynamic text field, but I can't figure out how to do it (I'm not
all that familiar with AS). I'm working with Flash 8. Please help.
Thanks.

Create the dynamic text box, and name it schedule.
Then, in the frame on the timeline that the text box resides
in, the corresponding actionscript would be used to create a text
variable and assign the text from a txt file to it:
loadText = new LoadVars();
loadText.load("externalfile.txt");
loadText.onLoad = function() {
schedule.text = this.textbody;
Where does the "textbody" variable come from? In the external
text file (externalfile.txt in this example), you have a variable
called textbody, and the externalfile.txt should read along the
lines of:
textbody = "I'm the external text that needs to be read
in"

Problem on reading and writing from from a *.txt file

I get Problem on reading and writing from from a *.txt file. The following is the read() method...

How to retrieve IndividualStrings from a txt file using String Tokenizer.

hello can any one help me to retrieve the individual strings from a txt file using string tokenizer or some thing like that.
the data in my txt file looks like this way.
Data1;
abc; cder; efu; frg;
abc1; cder2; efu3; frg4;
Data2
sdfabc; sdfcder; hvhefu; fgfrg;
uhfhabc; gffjcder; yugefu; hhfufrg;
Data3
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
i need to read the data as an individual strings and i need to pass those values to diffarent labels,the dat in Data3 i have to read those values and add to an table datamodel as 6 columns and rows depends on the data.
i try to retrieve data using buffered reader and inputstream reader,but only the way i am retrieving data as an big string of entire line ,i tried with stringtokenizer but some how i was failed to retrive the data in a way i want,any help would be appreciated.
Regards,

Hmmm... looks like the file format isn't even very consistent... why the semicolon after Data1 but not after Data2 or Data3??
Your algorithm is reading character-by-character, and most of the time it's easier to let a StringTokenizer or StreamTokenizer do the work of lexical analysis and let you focus on the parsing.
I am also going to assume your format is very rigid. E.g. section Data1 will ALWAYS come before section Data2, which will come before section Data3, etc... and you might even make the assumption there can never be a Data4, 5, 6, etc... (this is why its nice to have some exact specification, like a grammar, so you know exactly what is and is not allowed.) I will also assume that the section names will always be the same, namely "DataX" where X is a decimal digit.
I tend to like to use StreamTokenizer for this sort of thing, but the additional power and flexibility it gives comes at the price of a steeper learning curve (and it's a little buggy too). So I will ignore this class and focus on StringTokenizer.
I would suggest something like this general framework:
//make a BufferedReader up here...
do
String line = myBufferedReader.readLine();
if (line!=null && line.trim().length()>0)
line = line.trim();
//do some processing on the line
while (line!=null);So what processing to do inside the if statement?
Well, you can recognize the DataX lines easily enough - just do something like a line.startsWith("Data") and check that the last char is a digit... you can even ignore the digit if you know the sections come in a certain order (simplifying assumptions can simplify the code).
Once you figure out which section you're in, you can parse the succeeding lines appropriately. You might instantiate a StringTokenizer, i.e. StringTokenizer strtok = new StringTokenizer(line, ";, "); and then read out the tokens into some Collection, based on the section #. E.g.
strtok = new StringTokenizer(line, ";, ");
if (sectionNo==0)
//read the tokens into the Labels1 collection
else if (sectionNo==1)
//read the tokens into the Labels2 collection
else //sectionNo must be 2
//create a new line in your table model and populate it with the token values...
}I don't think the delimiters are necessary if you are using end-of-line's as delimiters (which is implicit in the fact that you are reading the text out line-by-line). So the original file format you listed looks fine (except you might want to get rid of that rogue semicolon).
Good luck.

Importing Text From A .txt File

Hey guys,
I'm looking for a way to import text from a .txt file but I'm totally lost. If someone could point me in the right direction that would be awesome

Hi Prails
This script is basically what you asked:
#target illustrator
#targetengine main
function copyText(){
    var textFile = File.openDialog ("Select the file");
    if (! textFile.exists || app.documents.length==0){
        return;
    textFile.open("r");
    var txtContent = textFile.read();
    textFile.close();
    var doc = app.activeDocument;
    var textItem = doc.textFrames.add();
    textItem.contents = txtContent
copyText ();
Basically what you need to do is declare the text file, open it, read the content and close it. Then, you create a new text item in the Illustrator document and write the content once catched into the text item.
You could continue to work with the variable "textItem" in my example script if you want to set properties like the size, color of the text, position and so on. Also, if you want, replace the first line of the function var textFile = new File ("~/Desktop/Test.txt"); by var textFile = File.openDialog ("Select the file"); so the scripts opens a dialog to ask you the file you want the copy the content.
Hope to be helped
Best Regards
Gustavo

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Populate a table reading the data from a TXT file

how can I populate a table reading the data from a TXT file?
thanks

Hey Kevin!
Using FORMS.TEXT_IO to bulk load data from a file strikes me as re-inventing the wheel. It is just about justifiable in a self-service environment, but I regard the EXTERNAL TABLE is a better solution for that situation as well.
The same applies to UTL_FILE. I think the ability to read text with UTL_FILE is primarily intended for read file-based configuration or file manipulation/processing rather than data loading.
Re-writing a text file into SQL statements is too much like hard work (even with an editor that supports macro definition and regular expressions) for no real benefit. You lose all the bulk load peformance you would get from SQL*Loader. But for QAD I'd probably let you off with it.
You missed out one obvious alternative: using Java to turn the contents of an XML file into a CLOB and inserting it into a table which is read by a PL/SQL procedure that parses the XML records and insert the retrieved data into a table.
Stay lucky, APC

How to calculate the number of vowels from a txt file. Pls give me a hand!!

Guys! How do i calculate the number of vowels from a txt file? I have to create a program to count the number of words, sentence, and vowels. So far I had managed to count the number of words. Now I need help on counting sentence and vowels! Pls give me a hand guys!

I first have to read from the file not the string.I
know how to read from a file. Now the problem ishow
to compare a character from a txt file!You fail to understand, that you have read the data
from the file into a string. Now loop over all
characters in the string. Forget about the file.
KajOr forget the scanners just as others have told you. Just read the file character by character using a FileReader.

Reading integers from a .txt file and computing means

I have a program that uses for loops to produce ten integers (1-10) are returns the average mean, geometric mean, and harmonic mean.
Now i need to change this program to read integers from a .txt file and return the same data. Basically i need to change my for statements that are incrementing to read the text file.
Thanks guys.

You haven't asked a question. You haven't posted code. What are you expecting here?
But I guess I'll take a stab at it and say you should look at the Scanner class
http://java.sun.com/javase/6/docs/api/java/util/Scanner.html
or BufferedReader
http://java.sun.com/javase/6/docs/api/java/io/BufferedReader.html
I'll never understand what makes people come to the forums, create an account, and ask a lazy question, when they could get a great answer much quicker through Google.
