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);

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 helpingonedbguru wrote:
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:
select
1
from
dual
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:
*GET NEXT ORDER NUMBER
EXEC SQL
SELECT (MAX(ORDER_NUM) + 1)
INTO :NEXT-NUM:IND-NULL
FROM PART_ORDER
END-EXEC.
IF IND-NULL < 0
MOVE 1 TO NEXT-NUM.
EXEC SQL
INSERT
INTO PART_ORDER
(ORDER_NUM,
ORIGIN_LOC,
ORDER_TYPE,
ORDER_STAT,
CREAT_TIME)
VALUES (:NEXT-NUM,
:LOC, 'R', 'O',
CURRENT TIMESTAMP)
END-EXEC.
MOVE NEXT-NUM TO MASK0.
PERFORM HEADER-PROC THRU HEADER-EXIT.
CREATE-ORDER-EXIT. EXIT. You got this:
*GET NEXT ORDER NUMBER
EXEC SQL SELECT (MAX(ORDER_NUM) + 1) INTO :NEXT-NUM:IND-NULL FROM
PART_ORDER END-EXEC. IF IND-NULL < 0 MOVE 1 TO NEXT-NUM. EXEC SQL INSERT
INTO PART_ORDER (ORDER_NUM, ORIGIN_LOC, ORDER_TYPE, ORDER_STAT,
CREAT_TIME) VALUES (:NEXT-NUM, :LOC, 'R', 'O', CURRENT TIMESTAMP)
END-EXEC. MOVE NEXT-NUM TO MASK0. PERFORM HEADER-PROC THRU HEADER-EXIT.
CREATE-ORDER-EXIT. EXIT. Oh, wait! See the same thing all the time in this forum ... not because someone thinks fewer lines = faster code, but simply because people are sloppy.
INSERT INTO PART_ORDER(ORDER_NUM,ORIGIN_LOC,ORDER_TYPE,ORDER_STAT,CREAT_TIME) VALUES (:NEXT-NUM,:LOC, 'R', 'O',CURRENT TIMESTAMP) ; -
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. -

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
SandyThere'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.

}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. -
How do you find the number of lines in a file?
I need to count how many lines there are in a file, I am using a BufferedReader to read in the data, but how can I find the number of lines?
ThanksThat depends. How do you define a line? Is it a specific number of
characters, a String that's terminated by a newline character or some
combination thereof? -
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?
ThanksActually, 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.

Dynamic Pie Chart: Counting the number of instances for each value
Hello my name is Tim and I am at a roadblock concerning a chart for a dashboard design.
I have a list with two fields:
Platform and Status. The list is customized in InfoPath. The
Platform field is located on the form as a drop-down menu with 6 entries.
Status is a choice field with 3 selection that is updated through the lifespan of the project (once item created, it is updated to "In process", once the project is closed, the field is updated to "closed."
My hurdle is viewing these dynamically in a Pie Chart. I am trying to display the number of project's "In process" for each Platform. So, if Platform A has 6 projects "In process" and Platform B has 3 projects "In process"
how can this be displayed in a pie chart?
At the moment, I figured there are two options: Chart View WebPart or importing an Excel worksheet.
Any ideas or solution on how to accomplish this?
-Tim DempseyThree options:
1. Create a list that holds your statuses. Then in your original list, create a lookup to the status list. In your status list, make a lookup to the lookup. This creates a circular reference which, for whatever reason, returns a count. You can then connect
a chart web part to this. Repeat for the other column.
2. Go to your sharepoint list and export to spreadsheet. Save the file. This is a query file that you can use as a data connection. From that file, set it to auto-update and then create a chart from a pivot table. Then use Excel Services Web Part to display
the file.
3. The other option is to use Google Charts API. Connect to the list, run some jQuery and JavaScript and then export out a chart. Pretty cool tool.

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

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.

Report for counting the number of interfaces in each device
Hi, we have LMS 4.0.1 and we would like to know how many gigabitEthernet interfaces and how many fastEthernet interfaces does each device have. If we create a custom report template with the conditions "Interface:Type:Contains:Gi" OR "Interface:Type:Contains:Fa" we get the interfaces that match the criteria but we also need the count, and this is what we don't know how to do it.
Does anyone know how can we do it?Hi
Suppress results rows for number of items..that is 10,20...
Calculate result rows only for sales order ...1000000...
You should get intended result with this settings

Count the number of rows in each table
I have a list of table names, how to I write a query to find out the row count of each table.
select table_name from all_tables a where owner='XXX' and num_row > 100
or
select table_name from all_tables a where owner='XXX' and sample_size > 100
doesn't quite work.
Why?
Thanks in advance,

How to count number of lines in a file?
I am using a BufferedReader to read my file, but I like to know how to count the number of lines in a file is there a way to do that in Buffered Reader or do I have to use FileInputLineStream?
Well, if you know how to read one line with a Buffered reader, and you know how to keep reading lines until you run out, then all you have to to is initialize a counter to zero before you start reading, add 1 to it each time you read a line, and then examine its value when you're done.
Try that, and post again if you get stuck.
Just be careful how you construct your loop. "Off by one" errors are a common way to get bitten. It could happen if you count what you think is the last line, but you've actually already counted all the lines and you end up counting one extra for "there are no more lines".
