How to count number of words in a string?

Is it only possible by counting the number of white spaces appearing in the string?

Of course that also depends upon how accurate you need to be and what the string contains. It is completely possible that there might be a line break which doesn't have a trailing or leading space.
Like that.
In that case Flash's representation of the string is likely "...space.\n\nLike that.." In chich case "space.\n\nLike" will be a word.
Also if you split on space and there are places where there are two spaces in a row you could inflate your number. So somthing that changes newlines (and returns) to spaces, then removes any multiple spaces in a row, and finally does the split/count thing would be more accurate.
But it all depends upon what you need.

How to count number of characters in a string?

Hi
I need to display values in a script. but the alignment getting distrubed if it is less than 20 charaters, for exmple material descirption is only displaying 20 characters in script. if it is less than 20 charcters the alignment getting changed.
please help me ...urgent..
thanks in advance...

solution to this problem in script is not to count the characters but to align them based on positions .
1.
Use the tab positions for that paragraph format to display the values in a finite format .
In this u need to give the position start and position end length and use the same in the script as
p ,,&itab-f1&
say my value has to print from position 125mm to 155 mm
i take one tab position for this paragraph format P and maintain the same in the output.
here ,, is the tab position .
See whether it is one character or 20 character it has to behave the same way it should not be misaligned .
check the tab position for that paragraph format in Tabs ..

vijay.

How to count the number of times a string occurs in a column.

I am listing team names in a column and want to have a tally at the bottom. In Excel I can use =SUM(IF(range="text",1,0)), but Numbers will not accept a range in that IF statement. ANy suggestions on a formula for his? I know I could create hidden columns and put formulas in all those and hen count them, but that sure seems like a heard way to resolve what should be one formula.
THanks!

Those which took time to read carefully *_iWork Formulas and Functions User Guide_* are aware of the availability of wildcard characters.
=COUNTIFI(range;"=text")
will do the trick.

Scanner -- how to count spaces a part of a string

I'm fooling around with Scanner in a little program just to teach myself. Right now, when given the chance to enter data, anything after a space is ignored, so, for example, if one enters "John Smith" for a name entry, on printout it only says "John." How can I fix this?

Melanie_Green wrote:
Opps forgot to close the scannerUmmm... As a general rule of thumb... If you open it, close it... and conversely: If you didn't open it, don't close it... any other way lies madness, like having to check if the stream has been closed by something else before every write. Yeck!
System.in, out, and err are opened and closed for you automatically... so you shouldn't (IMHO) close a scanner on System.in, because it would close the underlying System.in stream... which probably isn't what you wanted to do anyway.
And (just my humble opinion) I'd regard that "input loop" as "an abuse of loops"... because it's more complicated than it needs to be. However...
If one where to delegate the "simple attributes" of a "bean-like" class to a Map... Hmmm... the below code concept still isn't (IMHO) actually useful for real apps, because it's limited to String attributes only, but it was an interesting learning exercise none-the-less... and one could conceivably extend it to support all the primitive types, but what's the point... then you may as well just write simple old beans, forget about all the "clever stuff" under the hood, and get on with what the real problems ;-)

How to Look at current Token

When using the tokenizer in Java I see that you can count tokens "countTokens() " , see if a string has more tokens "hasMoreTokens()", etc. But how do you work with the current token?
For example:
while ((str = in.readLine()) != null )
     StringTokenizer tokens = new StringTokenizer(str);
     while (tokens.hasMoreTokens())
          System.out.println( tokens.nextToken() + "\n" );
          //tokenStr = tokens.nextToken();
          count++;
          //if (tokenStr.equals("<body>"))
          //     bodycount++;
         }I can count all the tokens in the string but how can I count the tokens "<body>"?
Any help please
eddiemjm

You are almost there. Trywhile ((str = in.readLine()) != null )
     StringTokenizer tokens = new StringTokenizer(str);
     while (tokens.hasMoreTokens())
          tokenStr = tokens.nextToken();
          System.out.println( tokenStr + "\n" );
          count++;
          if (tokenStr.equals("<body>"))
               bodycount++;
         }Note the change and move of the println() call.

How do I deal with Tokenized strings that are blank?

I'm writing a little application that writes data to a file. It sends data to the file as a "|" delineated string. Then I use tokenizer to break up the string as follows:
try {
                              String searchtext = SearchTxt.getText();
                              String tokenString = "";
                              String[] returnData = new String[8];
                              File filedata = new File("bigbase.txt");
                              BufferedReader in = new BufferedReader(
                              new FileReader(filedata));
                              String line = in.readLine();
                              while ( line != null) {
                              Pattern pat = Pattern.compile(searchtext);
                              Matcher mat = pat.matcher(line);
                                   if ( mat.find() ) {
                                   StringTokenizer t = new StringTokenizer(line, "|");
                                   maintextArea.setText("");
                                   int count = 0;
                                        while (t.hasMoreTokens()) {
                                             tokenString = t.nextToken();
                                             returnData[count] = tokenString;
                                             maintextArea.append(tokenString + " ");
                                             System.out.println(tokenString);
etc etc etc
The problem is that when the tokens are blank, I get an endless loop when I try to print out the data on that last line. How do I deal with Tokens that are blank so they don't endlessly loop my output?
Thanks
MrThis

Most people would probably tell you to use:
String.split(...);
But I'm not most people and I wrote this class before regex support was added to the String class which is based on StringTokenizer but supports empty tokens:

How to Count Number of completed line items in past 6 months / 12 months ?

How to Count Number of completed line items in past 6 months / 12 months ?
Hi,
I am trying to count "Number of Completed Line Items in Purchase Order Document" for my Key Figure ZPO_CNT.
Purchase Order document = ZEBELN
Line Item = ZEBELP.
I need to find and count if the Line Item has been received in the past 6 months from today and similarly in the past 12 months.
I have "Delivery Completed" field, ELIKZ.
So, based on this would I be able to calculate it in Query Designer?
If so, Please let me know how

Hello Deva
If youe want to calculate the completed line item for last 6 or 12 month then i think u will be displaying the query data for these montrhs...create a customer exit to give you date range and restric it in filter area....
Now Choose any of the below option
1. I would suggest to implement an additional key figure "counter" in cube and fill values with one for which delivery is completed.
Now use calculated key figure in Query Designer based on logic
IF counter = 1 THEN counter ELSE 0
OR
2. create a formula variable based on ELIKZ and use replacement path variable, it will display you no. of docs for which delivery is completed....
Award points if it solves your problem
Revert back in case of further assistance...
Thanks
