Count the number of lines in all of my java files.

I have created a reasonable size project with about 20 classes, rather than going through each and counting the lines are their any programs maby integrated into forte or another ide which can do this?
Thanks

Actually, if you are looking for kloc statitics, it is more complicated. You would not want blank lines counted. You may also want to separate out the counts for comments vs. code. Also seprations between JavaDoc comments and commented-out code. There are free and commercial programs which do this, or you can write your own.

Count the Number of Lines

Hi All,
I want to count the Number of lines that the user had entered in a multi-lined text box.
Because I want to restrict him up-to 6 lines.
How Can I don this.
Thanks in Advance,

How to count the number of lines dynamically,

In the below code am trying to read the lines which are selected using a check box, also am categorizing the contents depending on the follow up material.
after displaying one category contents am displaying a line
which also counts to a line in the internal table.
My question is how to count the number of lines(ULINE) displayed dynamically.

Count the number of lines in a txt file

I need to count the number of lines in a txt file, but I can't do it using readLine(). This is because the txt file is double spaced. readLine() returns null even if it is not the end of the file. thanks for the help

I need to count the number of lines in a txt file,
but I can't do it using readLine(). Then just compare each single byte or char to the newline (code 10).
This is because the txt file is double spaced. readLine() returns
null even if it is not the end of the file.Errm what? What do you mean by "double spaced"? Method readLine() should only return null if there's nothing more to read.

Count the number of lines in each file in a directory

Hello,
I would like to count the number of lines for each file in my directory and subdirectories.
I wonder how can I count the lines of the specified files?
Here is the program which is listed the files in the specified directory:
                    String path = "C:/User/Studies/Pracices/src/Pract1";
       String files;
       File folder = new File(path);
       File[] listOfFiles = folder.listFiles();
       for (int i = 0; i < listOfFiles.length; i++)
        if (listOfFiles.isFile())
     files = listOfFiles[i].getName();
     System.out.println(files);

Ok so one more question.
Actually my path is pointing to one Directory and like here I can just read from one file that the name of the file should be specified in the path is it possible to help me in that part?
File f = new File("C:/User/Studies/Practices/src/Pract1/");
FileReader fr = new FileReader(f);
      BufferedReader br = new BufferedReader(fr);
      String str = br.readLine();
          LineNumberReader ln = new LineNumberReader(br);
          int count = 0;
          while (ln.readLine()!=null)
              count++;
          System.out.println("no. of lines in the file = " + count);

Java Program+To count the number of lines in a method excluding comments???

Hi friends
can u plz help me out, the java program is counting the number of lines in a method excluding comments.
The first thing is how to identify a method, then there can be an inner method inside the parent method,
Please friends its urgent
Bye
Sandy

There's no such thing as an inner method in Java. You can either write the code yourself to parse Java source, or maybe something like ANTLR can do it.

Counting the number of lines for each procedure in a package

Hi,
I would like to write a query on USER_SOURCE that can display the number of code lines for each procedure/function in a package.
Is it possible to write such a query? Maybe by using analytical functions?
for example in the following example i would like to count the lines between "PROCEDURE proc1 IS" and "END proc1;" and between "PROCEDURE proc2 IS" and "END proc2;"
SQL> select text from user_source where name='PKG_TEST' and type='PACKAGE BODY';
TEXT
PACKAGE BODY PKG_TEST IS
PROCEDURE proc1 IS
BEGIN
    update t1 set EDITION_NAME = 'AAAAAAA';
    commit;
END proc1;
PROCEDURE proc2 IS
BEGIN
   update t1 set EDITION_NAME = 'AAAAAAA';
    commit;
END proc2;
END PKG_TEST;thanks for helping

Hopefully some idiot manager isn't trying to use this sort of thing to base their decisions on developer productivity. If so, they ARE idiots. Number of code lines NEVER, EVER, EVER!!! translates into an efficient application. If I were paid by the line, my code would look like:

Based on the idiocy of this method of determining "performance" I would get paid $5.00 at $1.00/line. And trust me, I saw this back in the 80's and 90's and saw similar idiotic code and had to clean up the mess. Most of it wasn't efficient code to start with let alone the number of lines generated.Or the other extreme, when the PHB firmly believed that execution efficiency was gained by reducing the number of lines of code. So instead of nicely formatted, easy to read code:

            EXEC SQL
                 SELECT (MAX(ORDER_NUM) + 1)

            END-EXEC.
            IF IND-NULL < 0
              MOVE 1 TO NEXT-NUM.

            MOVE NEXT-NUM TO MASK0.
            PERFORM HEADER-PROC THRU HEADER-EXIT.

Iterate through the lines and count the opening and closing curly braces. Whenever you see an opening one, increase the counter, when you see a closing one, decrease the counter. When the counter hits 0 again, you reached the end of the method.
I assume you know how to count lines while moving through a text line by line.

Count the number of occurences of a pattern in some files

Hi,
I am trying to extract some patterns in files using regex. I can easily extract the patterns using my program. I also wanted to count the number of occurences of the pattern in the files. For that I have written this code:
int count=0;
          while (m.find())
             System.out.println("Found Patterns: "+m.group());
             count++;
       System.out.println(count); //giving error saying identifier expectedUnfortunately I am getting an error saying identifier expected at the count line. What to do?
Thanks

Have EEM count the number of Lines

In *nix this is as simple as "wc -l" but unfortunately I can't seem to find a simple solution. For the purposes of this thread here is my test script...
event manager applet TEST authorization bypass
event syslog pattern "TRIGGER"
action 1.0 cli command "enable"
action 2.0 cli command "conf t"
action 3.0 cli command "show log"
action 4.0 cli command "COUNT NUMBER OF LINES FROM SHOW LOG -- $_cli_result"
Can someone let me know what action 4.0 would be in order to complete this task?
Thanks!

Actually, that parially worked. Perhaps you can help me troubleshoot the results I am getting.
Here is my test script:

Findind out the number of lines within a string - using buffered reader

Hi All,
Want to know the number of lines within a string..Sample code is there for reference..could u help me out how to have the number of lines in a string without java comments (i.e string within /**------*/ and // should be eliminated)
public class ReadLines {
     public static void main(String[] args) throws Exception{
          ReadLines rl = new ReadLines();
          rl.readLines();
     void readLines() throws Exception{
          String str = "/** This is a test message\n"+
               "* for testing\n"+
               "*/\n"+
               "import java.io.*\n"+
               "// this is again comment\n"+
               "public class ReadLines {\n"+
          BufferedReader reader = new BufferedReader(new StringReader(str));
          String line = "";
          int count = 0;
          while ((line = reader.readLine())!= null )
               //line = reader.readLine();
               count++;
          System.out.println(count);
}Thanks

Hi
What you need to do is parse the file in such a way that you read /*, */ and // as tokens. By that I mean rather than read a line at a time (although I'm sure you could), read it character by character. So every time you reach a new line character then increment the counter. But there are two casaes when you don increment the counter they are:
If you encounter a / followed by * then keep reading but if you encounter a newline character then DONT increment the counter ONLY continue counting when you read a * followed by a / (as this is the end of the comment)
If you encounter / followed by another / then do not count that particular line and go to the next line and continue counting from there.
Where I've written 'continue counting' this is subject to the lines that follow not conforming to the above two cases.
I hope this helps.

How can i read the number of lines written - in spreadsheet array?

hello NI,
I am writing file as spreadsheet format continuously, contains date, time, chanel1, channel 2, channel 3..... etc.
i just want to know how many lines has been written after file write....
Regards,

You count the number of line termination char. Se example
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

How to Count the number of TAB chars value '0A' in a line?

I have a requirement to count the number of TABs in a text file that I am processing (they must equal 75) to ensure that all the fields have been submitted on the file I am reading?
How do I identify the TABs in a line?
I have this so far:
         CONCATENATE gv_unix_file gv_lstfiles-name INTO gv_unix_file.
          OPEN DATASET gv_unix_file for INPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          CONCATENATE gv_unix_file_arc gv_lstfiles-name INTO gv_unix_file_arc.
          OPEN DATASET gv_unix_file_arc FOR OUTPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          DO.
            READ DATASET gv_unix_file into lv_str.
            IF sy-subrc <> 0.
              exit. "exit do loop, file is done.
            else.
              TRANSFER lv_str to gv_unix_file_arc.
            ENDIF.
          ENDDO.

Here is a sample code:
DATA: lv_string TYPE string,
      lv_tab TYPE c VALUE cl_abap_char_utilities=>horizontal_tab,
      lv_i TYPE i.
DATA: result_tab TYPE match_result_tab.
DO 3 TIMES.
CONCATENATE 'A' lv_string INTO lv_string SEPARATED BY lv_tab.
ENDDO.
" this is how you need to find how many tabs are in your transfer work area...
FIND ALL OCCURRENCES OF lv_tab IN lv_string RESULTS result_tab.
DESCRIBE TABLE result_tab LINES lv_i.
WRITE:'No. of tabs found:', lv_i.

Count the number of extracted lines

Access vekp with vekp-objkey = mkpf-xblnr and vekp-vpobj = '03' and vekp-uevel = blank.
Get field vekp-venum.
Access again vekp with vekp-vpobjkey = mkpf-xblnr and vekp-uevel = vekp-venum.
Count the number of extracted lines.

Hi,
First u should start writing the code on ur own:
here's some sketch:
tables: vekp, mkpf.
data: begin of itab_vekp occurs 0,
      venum like vekp-venum,
     end of itab_vekp.
data: begin of itab_mkpf occurs 0,
        xblnr like mkpf-xblnr,
      end of itab_mkpf.
data: count type i.
select-options: s_xblnr for mkpf-xblnr.
select xblnr from mkpf into table itab_mkpf where xblnr in s_xblnr.
select venum from vekp
into table itab_vekp
* for all entries in itab_mkpf
where vpobjkey = itab_mkpf-xblnr
   and vpobj = '03'
   and uevel = ' '.
if sy-subrc eq 0.
count = sy-dbcnt.
endif.

Help with how to count the number of tokens from the first line

}     2.

I can print out the amount of tokens from each line,
But i only want the first line to be counted, And i
also do not want the delimeters to be counted.
could you please give me some ideas?
Thanks
try
   BufferedReader br = new BufferedReader(new FileReader("item.kr"));
   while((str=br.readLine())!= null)
      itemslist.add(str);
catch(IOException ioe)
   System.out.println("Exception Occurred!!!");
}This snippet gets one Line from the item.kr file.
Then i would count (By useing a diffrent String Tokenizer) to count only this line!!!

Count the number of lines in all of my java files.
