Java loading text file and doing stuff help

Hello,
Can anyone help me with this, I just don't know where to start..
I need to create a java program which will load up a text file. The text file must be no bigger than 1000 characters (so somewhere there needs to be an exception I am guessing)
Once loaded, it needs to run some methods on the text file which each return a single statistical count, the methods need to count things like number of white space, number of vowels, frequency of each vowel (this would not need to return a single count but maybe update some sort of array?) , number of printable characters and number of consonants.
Any help would be very good.
Dean

Thanks for the help so far
But first things first, I should start at the
beginning.
I am thinking maybe start with something like from
the Sun tutorial for 'CopyCharacters.java'.
So we have the first part of the program that loads
up the txt file....
(I really would like to have GUI for this, but I
can worry about that once the actual program is
working
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
public class CopyCharacters {
public static void main(String[] args) throws
IOException {
FileReader inputStream = null;
FileWriter outputStream = null;
try {
inputStream = new
FileReader("input_characters.txt");
Right, now its time to actually read what is in the
file and use some of the statements you have
suggested, can anyone help me get started with this?
Dean
public class DeanHomeworkAssignment {
public static void main(String args[]) {
//Put your code here
}There ya go, that should get you started.
Start by writing the code to open the file.
This isn't that difficult.

Domain Value Mapping with Text file

Hai,
I have done the Domain value mapping with the xml file to xml file and it is working fine.
But in the case of Text file to Text file it is not working i.e. If the citiname is the
first field it is domain value mapping and working fine.
INPUT:
Erode, Mahes, 22
Coimbatore, Veera, 22
OUTPUT:
ED, Mahes, 22
CBE, Veera, 22
But if I change the Citiname to the second column it is not working the problem is
it is not working for subsequent columns.
INPUT:
Mahes, Erode, 22
Veera, Coimbatore, 22
OUTPUT:
Mahes,, 22
Veera,, 22
The input Text files are delimited by "comma" and optionally enclosed by "space".
Does anyone have attained the DVM in the Text file successfully.
Please help me.

Thank you for the reply Abhi
Text to Text means instead of giving the input file as XML file i am giving the input as a simple .txt file and I also want the output in the .txt format.
For the text file only it is not working fine in the xml file to xml file it is working fine.
For your another query I am not providing the correct parameters for "lookup-dvm"
I am giving the xsl file

Here I am checking the DVM function for the Second column and it is not working and I have given their Inputs and Outputs in my first message .
I have another question as you told both import and export of the DVM is always in the XML format only so I have a doubt whether the lookup-dvm will be working for xml files only and not for text files.
But in my case in text file it is working for the first column but not in the subsequent columns.
Thanks.

Hi, Rama!
Unfortunatly it' s beyond the scope of this forum to give that detailed advice on basic java se techniques like opening a file input stream and working with collections.
Please refer to the suns standard documentation on file i/o and collections for detailed information on that.
If you' ve any additional questions on more SAP specific problems, don' t hesitate to ask!

Java newbie & text files

I want to create a simple program that will read a text file and put it in a variable to use later in the program. I can't figure out how to assign characters from the text file to a variable. Please bear with me, this is my latest attempt:
import java.io.*;
public class FileReader1 {
public static void main(String[] args) throws IOException {
     File inputFile = new File("nfo.txt");
FileReader in = new FileReader(inputFile);
String intext;
int c;
while ((c = in.read()) != -1)
intext = (String)in;
in.close();
System.out.println(intext);
}

I used the BufferedReader method on the FileReader method to get a string instead of characters, thus I could easily assign the value to a string variable. Below is my solution:
import java.io.*;
public class FileReader1 {
public static void main(String[] args) throws IOException {
     File inputFile = new File("nfo.txt");
FileReader in = new FileReader(inputFile);
          BufferedReader br = new BufferedReader(in);
          String s;
          String intext="";
while ((s = br.readLine()) != null)
          intext = s;
System.out.println(intext);
in.close();
}

How to create a mapping with text file as my target

Email with Text File Attachement as Source

Hi All,
One of my interfaces needs to listen to incoming mails with an text file attachements.I wish to know how we can convert the text file contents into XML to further process it on the reciever side.

Hi,

Michel: sync gtasks with text files

I wrote Michel, a gtaks-to-text-file synchronizer. Michel is your friendly mate that helps you managing your todo list. It can push/pull flat text files to google tasks.
Right now, it features two commands:
michel pull
prints the default todo list on the standard output
michel push <TODO.txt>
replaces the default todo list with the content of TODO.txt
Of course you need a gmail account to make it work. It uses oauth, so when you start it the first time, it will give you an url to visit and you'll have to give access to the app, then it will save a token and won't ask next time. If you want to delete the token, it is stored in $XDG_DATA_HOME/michel/oauth.dat.
The code is on github. As usual comments and patches are welcome...

Oh, I have to add that currently, the package won't build correctly. That is not due to the python2-google-api-python-client package which does not set the rights correctly. A quick and dirty fix is to
# chmod +r /usr/lib/python2.7/site-packages/google_api_python_client-1.0beta4-py2.7.egg-info/top_level.txt
I notified the owner of python2-google-api-python-client of the correct change to do.

Receiver mail with text file attached without line feeds

Hi, friends
I have a text file to mail scenario, where file must be attached to receiver mail.
Receiver CC mail is protocol XIPAYLOAD and use mail package and keep attachment.
In tab module, i have:
Module name --> SAP XI Sample/ConvertCRLFfromToLF
Module configuration --> mode LFtoCRLF
The plain text file is attached to mail but there are no line feeds after the plain text lines.
Thanks, in advance

Stefan,
This is not a Java mapping, it's an ABAP mapping.
I've tryed also to insert this characters, but without success.
In my abap class i have:
data: l_newline type c value cl_abap_char_utilities=>newline.
data: l_linefeed type c value cl_abap_char_utilities=>CR_LF.
clear wa_string.
incode = idocument->get_elements_by_tag_name( 'linea' ).
length = incode->GET_LENGTH( ).
do length times.
    outcode = incode->get_item( index = d_lines ).
    wa_linea = outcode->get_value( ).
    if wa_string is initial.
      wa_string = wa_linea.
    else.
      concatenate wa_string l_newline l_linefeed crlf wa_linea into wa_string.
    endif.
    add 1 to d_lines.
enddo.
l_element_dummy = l_document->create_simple_element(
                name = 'Content'
                VALUE = wa_string
                parent = l_element_root ).
so...it's similar to your suggestion..
Any other input, please?
Regards,
Carme.

Compare with text file

Is it possible to do a line by line compare with the data in a text file and print the required data?
BufferedReader readCode = new BufferedReader(new FileReader("code.txt"));
String code = readCode.readLine();
while(more) {
System.out.print("Code:");
String productCode = in.readLine();
while (code != null){
     code = readCode.readLine();
     if (!(productCode.equals(code) || productCode.equals(code) || productCode.equals(code) ||productCode.equals(code) || productCode.equals(code) || productCode.equals(code) || productCode.equals(code) || productCode.equals(code))){
     // Goes back to the next loop interaction. Skiping the rest of the loop below
     System.out.println("Invalid product code. Check the product code again");
     continue;
productTemp[j] = productCode;
do{
     /*Keep asking for a quantity until some valid value is entered
     System.out.print("Quantity[0-100]:");
     productQuantity = Integer.parseInt(in.readLine());
}while(productQuantity > 100 || productQuantity < 0);
quantity[k]=productQuantity;
totalQuantity = quantity[k] + totalQuantity;
j++;
k++;
noOfItems++;
}     i cant seem to compare the user input code with the code in my textfile.i am stuck here...can somebody enlighten me?

nvm...thanks for ur help anyway..i try others
ways..save ur remarks for other pplThis is a public unmoderated forum. If you don't want remarks, don't post.
Besides, if you're not willing to describe your problem in better detail, what kind of "help" do you expect? It's not like you've entered a forum full of psychics. Your problem is unclear.

Good luck.

Reloading a 3500XL with Text File

How do I clear the config and reload the switch with a text file? I have the file ready to go but can't figure out how to get it to take. Any help would be appreciated. Thanks.

Erase startup
reload
N Don't do the config!
enable
copy and paste the text file
ATTENTION do NOT paste from a Wordprocessor like MS-WORd, they add all the ugly control codes(especially fun at the password!)

Help required with text file handling in GPIB

Hi attached is my vi for GPIB communication with Aginelt Network Analyzer in Labview 8.
I'm saving the data of network analyser into text file(appending all the data). I wish to make some changes into it. As can be seen there is a input which asks for number of points/segments. Supposed I give that input as 201 points(it can be 401,801,1601,51,etc.) than after every 201 points data should get appended into a new coloumn and not into 202 row. Seperate coloumn should start for the whole set of 201 points, where as currently what is happening is all the data is getting appended one below the other.
Can anyone help around,
Regards

Problem with Text file attachment

Hello All,
I am sending data from my program via mail in an attachment of text format in 4.6C. But the format of the data in the attachment is not correct. There is no line break in the data.
I've tried putting the line break manually by using hexadecimal code '09' as the line break. But it is not working.
Kindly suggest.
Thanks

Hello Brad,
I marked the problem as solved previously because the issue of all the lines coming together was solved.
So, I marked the question as solved.
Now, I have a different problem and rather than creating a new thread I opened this one only.
Thank you
