String Letter Count

I must create a program that reads in a string from the user then prints out the occurance of each letter of the alphabet using the charAt() method. Can I get a little help starting?

import java.util.Scanner;
import static java.lang.System.out;
public class Project5B_2{
public static void main(String[] args){
     //Create Scanner
Scanner scan = new Scanner(System.in);
int another=1;
while (another == 1) {
     //Set Variables

int countA=0;
int countE=0;
int countI=0;
int countO=0;
int countU=0;
int countY=0;
int countSpace=0;
int countOther=0;
out.print("Enter a string: ");
str=scan.next();
str=str.toUpperCase();
for(int i = 0; i < str.length(); i++) {
if(str.charAt(i) == 'A') {
countA++;
else if(str.charAt(i) == 'E') {
countE++;
else if(str.charAt(i) == 'I') {
countI++;
else if(str.charAt(i) == 'O') {
countO++;
else if(str.charAt(i) == 'U') {
countU++;
else if(str.charAt(i) == 'Y') {
countY++;
else if(str.charAt(i) == ' ') {
countSpace++;
else {
countOther++;
out.println("No. of \'A\' or \'a\' = " + countA);
out.println("No. of \'E\' or \'e\' = " + countE);
out.println("No. of \'I\' or \'i\' = " + countI);
out.println("No. of \'O\' or \'o\' = " + countO);
out.println("No. of \'U\' or \'u\' = " + countU);
out.println("No. of \'Y\' or \'y\' = " + countY);
out.println("No. of spaces = " + countSpace);
out.println("No. of other characters = " + countOther);
out.println();
out.print("Do you want to continue? (1=yes, 0=no) ");
another = scan.nextInt();

Letter count when SMS-ing. Update or allready usable??? Please reply!

I wondered if the Iphone could get a Letter-counter when SMS-ing? It would be really great if I could see how many letters when I am SMS-ing, because I don’t want to waste a SMS's airtime because I was out with one letter.
If this isn't yet available on the phone can you please put it on the next update?
Thanks allot for your hard work

I don't think that is a definite way to determine if a text will be sent as one or two messages. A standard text message (well at least in the UK) is 160 characters including spaces.
It you type a upper case W then it takes up much more space than a lowercase l.
I just tried it and could only get 56 W's on four lines but I can get 240 l's on four lines.
So just be careful if texting in your country is also restricted by the number of characters sent as you may well go onto two messages if you rely on the four lines suggestion.
I would personally love to see a character counter and would suggest you send feedback to apple and hopefully this feature will appear in a future firmware update.

Letter count in multiple Id documents?

Hello,
I'm working on a book project. The single chapters are single files. Additionally I have one Id document where all documents are displayed/link for preview reasons.
Now to my question: is there a possibility to do a letter count the gives me a total number? ... the sum from all linked indesign files?
I look forward to your reply and send best regards,
Christin

Open all the files
Find/Change
Go to the grep tab
Find
\w
Change to
$0
The find change result dialog box will display how many letters were changed - but nothing is changed as you have opted to change to found text - which is the same.
You just get a number that represents how many letters were changed, which is your letter count.

Find one character in a string and count the amount of times its found

Hey SQL Forum experts.
I have a string that is about 3000 characters long.
I'm trying to search my string for the value '{'.
Then I want to count how many times this value is found.
How do I form the Oracle SQL to do this?

Hi Colin,
Try the following:
SQL> var s varchar2(100)

SQL> exec :s := 'Colin {{ Mackenzie {{{'
PL/SQL procedure successfully completed.
SQL> select length(:s) - length(replace(:s, '{')) Matches from dual;

Library quick letter count.

Hi all,
we have a library function in the intranet site. On the top of the page we have the letters A until Z.
We like to make the letters bold if there is a file under.
All the information is stored in 1 DB table.
I am thinking aboute a query something like this:
SELECT COUNT(pk) FROM lib WHERE desc LIKE 'A%' or desc like 'a%'
I have to do this by a until z and not willing to do a query fore every letter.
How do i make a query/system to do this in a singel run?
Thanks, Johan.

This is actually a question about SQL and your database, isn't it? Your database's version of SQL probably has a "substring" function and a "convert-to-upper-case" function. You could look it up or ask in an appropriate forum.

String reference count

Hi,
is copy a string to another string a real copy or is it just an increment of the reference count to it. For example if used like this:
private void foo()
     String data = getFooData();
     lastData = data;
     if (someThingTodo) {
          // do something
          lastData = null;
}If it is a question of reference count, then this code only increment, and eventually decrement it, right ?

Assigning to a reference type--String, Object, List, MyClas, etc.--never copies the object. It always just causes the reference on the left side to point at the same object that the reference on the right side points to.
Java doesn't use reference counting for its memory management. But if your question about decrementing is in the vein, "Will the VM automatically detect when an object can no longer be reached and make its memory available for use by other objects?" then then answer is yes, that's taken care of for you.

String function to count total number of a specific character.

Gurus,
I've been trying to use INSTR to decipher a string to count the number of pipes in each string. Anyone have a simple SQL which shows how to use a string function to return a count of a specific character?
Thanks
-Scott

Hi, Scott,
To see how many '|' characters are in txt, you can see how much txt shrinks when you remove the '|'s.
LENGTH (txt) - NVL ( LENGTH ( TRANSLATE ( txt
                                                  , 'x|'
                         , 'x'
             , 0
             )The expression above works in any version of Oracle.
Starting in Oracle 11, you can also use REGEXP_COUNT:
REGEXP_COUNT (txt, '\|')'|' is a special symbol in regular expressions, so it has to be "escaped" ('\|') to indicate the pipe character.

Counting strings

Hi, what i'm trying to do is to count how many times every possible three-word-string (in a logical order ie 1-3, 2-4, 3-5...) occurs in a file.
public class Blandning2 {
public static void main(String[] args) throws Exception {
     String strang;
      int count = 0;
      int rakna = 0;
          Scanner sc = new Scanner(new File("test.txt"));
          Pattern p = Pattern.compile("\\b(\\w+)\\s+(?=(\\w+)\\s+(\\w+)\\b)");
              while (sc.findWithinHorizon(p, 0) != null) {
                  MatchResult m = sc.match();
                  count++;
               strang = m.group(1) + " " + m.group(2) + " " + m.group(3);

                Scanner scc = new Scanner(new File("test.txt"));
                while (scc.findWithinHorizon(findstrang, 0) != null) {
                  MatchResult mandra = scc.match();
                  rakna++;
                   System.out.println("string number " + count + ": " + strang);
                   System.out.println("occurs: " + rakna + " times");
} the file it reads is looks like this:

anyone who can see my mistake?
thank you in advance

I see two major problems with that code: the regex you're generating for the inner loop won't match if the whitespace within a three-name group is anything other than a single space character, and your hit-counter never gets reset. But that's a bad approach anyway. Instead of scanning the file over and over, you should scan it just once and use a Map to store the hit counts. import java.io.*;
import java.util.*;
import java.util.regex.*;

    String current = null;

NI 6343 Internal DI Sample Clock counter name text string?

I need to add a frequency test to my remote site (remote debug). Could someone tell me the text string as counter name for NI 6343 Internal DI Sample Clock? Thanks.

Does your remote computer have MAX installed? This is the easiest way to see what the device alias is.
You can always just try Dev1 and see if it works. This is the default when the very first device is added to a system.
If you can deploy code to the remote system, you can also use the DevNames property of the System Node from the DAQmx System Setup palette. This will show you all of the names of the devices in the system and you should see your device there.

How to search for upper/lower case using string using JAVA!!!?

-I am trying to write a program that will examine each letter in the string and count how many time the upper-case letter 'E' appears, and how many times the lower-case letter 'e' appears.
-I also have to use a JOptionPane.showMessageDialog() to tell the user how many upper and lower case e's were in the string.
-This will be repeated until the user types the word "Stop".
please help if you can
what i have so far:
[code]
public class Project0 {
public static void main(String[] args) {
String[] uppercase = {'E'};
String[] lowercase = {'e'};
String isOrIsNot, inputWord;
while (true) {
   // This line asks the user for input by popping out a single window
   // with text input
   inputWord = JOptionPane.showInputDialog(null, "Please enter a sentence");
   if ( inputWord.equals("stop") )
    System.exit(0);
   // if the inputWord is contained within uppercase or
   // lowercase return true
   if (wordIsThere(inputWord, lowercase))
    isOrIsNot = "Number of lower case e's: ";
   if (wordIsThere(inputword, uppercase))
     isOrIsNot = "number of upper case e's: ";
   // Output to a JOptionPane window whether the word is on the list or not
   JOptionPane.showMessageDialog(null, "The word " + inputWord + " " + isOrIsNot + " on the list.");
} //main
public static boolean wordIsThere(String findMe, String[] theList) {
for (int i=0; i<theList.length; ++i) {
   if (findMe.equals(theList[i])) return true;
return false;
} // wordIsThere
} // class Lab4Program1
[/code]

So what is your question? Do you get any errors? If so, post them. What doesn't work?

Reading a file, and counting how many e's there's in it!

Hello everyone!
Well, I'm trying to write a program that'll read a file and count the number of e's in there and print it out.
This is what the Index.txt file contains:
In Xanadu did Kubla Khan
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea.And this is my source code:
import java.io.*;
public class Appearance{
    public static void main(String[] args) throws IOException{
     index = new BufferedReader(new FileReader(("Index.txt")));
        while((letter = index.readLine()) != null){
   if(letter.contains("e")){
       eCount++;
System.out.print(eCount + "\n");
if(index != null){
      index.close();
   index = null;
private static BufferedReader index = null;
private static String letter = null;
private static int eCount = 0;
}But for some reason when I run it, the output is 4?.. Please tell me why, as I figured that this should work.. :O.

Vimsie wrote:
But for some reason when I run it, the output is 4?.. Please tell me why, as I figured that this should work.. :O.Because you are counting the number of lines that contain one or more 'e's. You don't count the occurances.

Counting number of lines in a text/csv file using xquery/xslt.

Hi,
I have a CSV file, I need to count the total number of lines in that file. This I have to use in OSB. My requirement is I have to count total no of lines in the $body file (CSV/flat file) and subtract header and footer lines from it.
EX:
header,1, @total_no_of_detal@
detail,1
detail,2
detail,3
detail,n
footer, 1
If suppose i have 10 detail lines, and I am getting body of the file as shown above,
then in the final file, I have to change the body of the file as:
header,1, *10*
detail,1
detail,2
detail,3
detail,n
footer, 1
Please advice how to do this in OSB.
Edited by: user12679330 on Aug 2, 2011 2:34 AM

I would suggest you to use MFL to convert the file into XML when you read it and then you can count the detail elements within the XML and update the values in Header element before writing the file again in flat file format again using MFL.
You can read the documentation of Format Builder utility which is used to define MFL here:
http://download.oracle.com/docs/cd/E21764_01/doc.1111/e15866/part_fb.htm
Alternatively, another approach is the read the whole flat file as a text string and then doing needed manipulations to get what you need. If you want to do it like this then you will need to consider following things:
1. Is the file in DOS format or Unix format? (To know the End of line character in use)
2. Does the file contain an end of line at the end of file? (whether there is an end of line char at the end of data of footer record)
Once you know above, you can try an xquery like following:
let $intermediateXML :=
<Root>
for $a in (tokenize($in, 'EOL'))
return
if (string-length($a) > 0)
then
<record>{$a}</record>
else ()
</Root>
let $count := count($intermediateXML/record)
let $outXML :=
<OutRoot>
for $i in 1 to $count
return
if (data($i) = 1)
then
<Record>{concat($out, $intermediateXML/record[$i]/text(), ',Count=',($count)-2)}</Record>
else
<Record>{concat($out, $intermediateXML/record[$i]/text())}</Record>
</OutRoot>
return op:concatenate($outXML/Record/text(), 'EOL')In Above XQuery, replace EOL with the end of line character which for unix wound be "&#xA ;" (remove quotes and space between the A and ; ) and for DOS would be "&#xD ;&#xA ;" (remove quotes and space between the A and ; and D ; )

[SOLVED] An elagant solution for: C to Shell? About strings

Hello:
I'm a newbie at Shell. I would like to traduce a C code to Shell. I would ike to make it compact BUT legible (not so cryptic as Shell could allow).
This is the original C code (the explanation of the files -input- are bellow, in the shell part):
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#define BUFF_SIZE 512
static void Check(char *InputFile, char *OutputFile)
FILE *fpi,*fpo;
char Buffer[BUFF_SIZE+1];
int CntRec = 0;
fpi = fopen(InputFile,"r");
fpo = fopen(OutputFile,"w");
if (fpi) {
memset(Buffer,0,sizeof(Buffer));
while (fgets(Buffer,BUFF_SIZE,fpi)) {
if ((strlen(Buffer) > 100) && (!memcmp(Buffer,"5698",4))) {
fputs(Buffer,fpo);
CntRec++;
memset(Buffer,0,sizeof(Buffer));
fclose(fpi);
fclose(fpo);
printf("Number of registers = [%d]\n",CntRec);
This is my first attempt with Shell:
#!/bin/bash
# Program:
# Gomy, FILL THIS, DO NOT FORGET!
# Synopsis:
# Read from a file each line, which has the following format:
# nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnl000000000000nnnnnnnSTRING [... more n and l's]
# where:
# n is a <positive int>
# l is a <char> (no special chars)
# The program should check that each line of the file:
# I) Has at least a [MIN_LENGHT] character length.
# II) The first characters of the string has a pre-defined
# pattern, in this case: MATCH_PATTERN
# If the line do not match [i] and [II], it should be copied
# in an output file for further analysis. Also, the number
# of those cases must be shown.
MIN_LENGTH=100
MATCH_PATTERN="5698"
counter = 0
#Read all the lines of the file.
while read line
do
len=${#line} #Store the length
pattern=${line:0:4} #Store the first x chars for contrast with [MATCH_PATTERN]
if [[ "$len" -lt "$MIN_LENGTH" && "$pattern" = $MATCH_PATTERN ]]; then
$line > output.txt
$counter++
fi
done
exit
Well, the If works. Never the less:
I) why I have to use a [[...]] instead of [].
II) The $line > output.txt is not working for me. It says: [STRING FROM FILE] command nor found.
III) Also the counter, with the ++ is not working.
IV) When I run the program, I do it like:
sh check.sh < test.txt
(or ./check <test.txt)
But I would like to do it like:
sh check.sh input.txt output.txt
I also tried to do it with awk, but my attempt failed:
awk '{ line=$0; print (length($line)) }' input.txt
could not manage the if's and others conditions so well!
Well, if you could give some tips, I would be delighted.
Thank you!

Hello: Thank for your answer, I took some of your code, and did this:
# Check the number of arguments that could be passed.
if [[ ${#@} != 2 ]]; then
echo "Wrong # of parameters...Use: check<inputfile> <outputfile>\n"
exit
fi
#Inputfile: is in position 1 on the ARGS
inputfile=$1
#Outputfile: is in position 2 on the ARGS
outputfile=$2
MIN_LENGTH=100
MATCH_PATTERN="5698"
#Read all the lines of the file.
# Notice: "read -r" Do not treat a backslash character in any special way.
# Consider each backslash to be part of the input line.
while read -r line
do
len=${#line} #Store the length
pattern=${line:0:4} #Store the first x chars for contrast with [MATCH_PATTERN]
if [[ "$len" -lt "$MIN_LENGTH" && "$pattern" = $MATCH_PATTERN ]]; then
(( ++count ))
echo "$line" >> "$outputfile"
fi
done < "$inputfile"
printf 'Number of registers: %s\n' "$count"
But I have some questions:
I) In your code, why use:
done < inputfile
. I don't get it. With the "while" is not enough to read all the file.
II) Is it OK to use inputfile=$1 and outputfile=$2 that way?
III) I did not find why (( ++count )) works in shell! Using
let count = count + 1
works, but that way you did it is more elegant.
IV) Puting "exit" at the end is redundant?
Thanks for the guide, is more compact that the one I was/am reading

StringBuilder to String.

Hi im doing a Open uni course and am getting read to sit my exam so i have downloaded some old test papers and have been going throught them and am stuck on one question that takes a file and the reads from said file one line at a time and changes each char into another char so if i had an A it would change it to an int then add - 3 to it and then take the new string and write it to a new file i have coded.
import ou.*;
import java.io.*;
import java.util.*;
public class cipher
public static void encryptFile()
String pathwayRead = OUFileChooser.getFilename();
String pathwayWrite = OUFileChooser.getFilename();
File readFile = new File(pathwayRead);
File writeFile = new File(pathwayWrite);
BufferedReader bufferedFileReader = null;
BufferedWriter bufferedFileWriter = null;
StringBuilder temp = null;
String currentLine;
int counter = 1;
int letter;
try
   bufferedFileReader = new BufferedReader(new FileReader(readFile));
   bufferedFileWriter = new BufferedWriter(new FileWriter(writeFile));
   currentLine = bufferedFileReader.readLine();
   while (currentLine != null)
         if (counter == 5)
            counter = 1;
          for (int i = 0; i < currentLine.length(); i++)
            temp = new StringBuilder(currentLine);
            letter = temp.charAt(i);
            System.out.println((char)letter);
            letter = letter - counter;
            System.out.println((char)letter);
            temp.deleteCharAt(i);
            temp.insert(i, (char)letter);
            System.out.println(temp.charAt(i));

finally
   try
      bufferedFileWriter.close();
      bufferedFileReader.close();
   catch(Exception anException)
      System.out.println("Error: " + anException);
}the System.out.println show me that the char are being changed as i wish but they are not being written like this.
say in one file i have the work "luke" i read in this file and the output file would have "lukd".
