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?
Thanks

That 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?

How do you find the number of songs in your library, more importantly the number of duplicates, this new version is very lacking in access to info

I do not like the interface of the new version. I lost a lot of playlists and songs in the iMatch process. As I attempt recovery from backups, I am trying to identify how many duplicates I have in total. I can get a list, but there are too many to count. There has to be a better way.
thanks

View > Show Status Bar puts the grey bar at the bottom where song/playlist stats are displayed
In itunes 11 the Show duplicates feature was omitted.
However in iTunes 11.0.1 they put it back
from the top menu

I know this post was a long time ago but people still seem to be viewing it.
Quickest way:
Via the iPad on 3G, go to http://m.telstra.com. The service number is then displayed and you are given the option to recharge.

How do I increase the number of lines presented in a drop down list?

When I am entering a single character/number for each of a random selection of three letters in a password verification, I get a drop down list from A to S only, the first 20. Accessing letter T to number 9 means scrolling down. How can I increase the number of lines in a drop down box to 36?

Hi canddski,
If you are taking about an interface on a website, this is up to the ui designer. But there is a reflow that depends on screensize for the Firefox UI.
You can use asp to control the list:

Oracle Linux behaves exactly like Red Hat in this matter an /proc/cpuinfo can be used for that. I guess this is because you have set up VirtualBox to only assign one virtual CPU to your guest Linux.

Hi,
To get the depth using JMS you must create a QueueBrowse and browse the entire queue. Its generally horribly inefficient if you want to do it with any regularity.
In Hermes I have had to write plugins that open separate connections to providers using their non-JMS APIs or JMX and get that kind of information that way.
Look at the getDepth() method in this JBoss plugin for an example that uses JMX:

And here is one for WebSphereMQ that uses one of its many APIs..

When people call me, Skype rings far to many times before voice mail comes on. How do you reduce the number of rings on an inbound call, so that voice mail comes on in 4 to 5 rings?

Hi, billwalker1125,
Skype does not determine when to send calls to voice mail by the number of rings, but instead by the amount of time that has elapsed. Check your settings (in Windows, it would be Tools -> Options -> Calls -> Voice Messages -> Start recording a voice message if ... Remember to Save your changes!

If you are trying to find word count in a Microsoft Word 2011 documemt, for instance, open the document and go to the Tools menu, selecting Word Count. In Apple's Pages application, open the document and look at the bottom of the page, near the left it will say "X Words" where X is the number.
Best of luck.

How do you show the number of days per month?

How do you show the number of days per month?
I am working on a budget. I want to know how much to amortize each month to fund an investment. Income comes monthly, but expenses leave in days, or weeks. The number of days and weeks in months vary.
I want to figure out income and expenses per day, per month and per year, so I know how much can be invested each month, week or day. For a start I would like a formula that shows how many days are in each month?

thanks..
I solve my problem as
public class MyExample {
    public static void main(String a[]) {
        String stdate = "2009-03-01";
        java.sql.Date currentDate = new java.sql.Date(System.currentTimeMillis());
        java.sql.Date preDate = java.sql.Date.valueOf(stdate);
        System.out.println(currentDate);
        System.out.println(preDate);
//        int dateCom = preDate.compareTo(currentDate);
//        System.out.println(dateCom);
        long diff = currentDate.getTime() - preDate.getTime();
        int days = (int) Math.floor(diff / (24 * 60 * 60 * 1000));
         System.out.println(days);

How do you set the number of rows in a spreadsheet, so that even when you drag data in, in writes over those rows instead of adding a new row?

How do you set the number of rows you want in a spreadsheet, so that even when you drag data in, in writes over those rows instead of adding a new row?

After the discovery reported above, I filed this report :
Bug ID# 10073038
Summary:
When Numbers is used on a system with decimal comma a csv file may be good AND wrong
Steps to Reproduce:
With Numbers v2, you introduced an interesting enhancement.
In system using the comma as decimal separator, Numbers requires csv files using the semi-colon as values delimiter.
In fact it’s true if we OPEN the document dragging its icon on Numbers one or thru the open dialog.
This said.
(1) Drag and drop a csv built with the 'semi-colon' standard on a table or on a sheet
(2) Drag and drop a csv built with the 'comma' standard on a table or on a sheet
Expected Results:
Every normally constituted user assume that in
case (1) he will get a perfectly built table
case (2) he will get every cells of a row in a single cell
Actual Results:
In fact you forgot the drag and drop way of use and in
case (1) every values separated by semi-colon are inserted in a single cell
case (2) values separated by comma are correctly spread in a table
isn’t it ridiculous ?
Regression:
Except looking in QuickView to see which is exactly the structure of the file to decide the way we will insert it in a Numbers document, we may use an applescript fair enough to replace the semi-colons by TAB characters
or
to replace the commas by TABs and the decimal periods by commas
Notes:
While I am on this subject, I wish to make two proposals:
(1) It would be fine to format the date according to the ISO format year-mm-dd when you export a Numbers doc to csv.
Doing that, dates would be imported correctly in every countries.
At this time, on an English system, you export as mm/dd/year.
If the doc is open on a system using the format dd/mm/year, the results will be odd.
On a system using the format dd/mm/year, you export this way and so, if the doc is open on a system using the format mm/dd/year the results are odd too.
As every localized versions accept the ISO format (at least on entry), using it in the export scheme would give a correct behavior everywhere.
(2) It would be fine to add the format Tab Separated Values in the Export pane.
TSV + ISO date format would give documents opening flawlessly everywhere.

How do you return the number of Rows in a ResultSet??

How do you return the number of Rows in a ResultSet? It's easy enough to do in the SQL query using COUNT(*) but surely JDBC provides a method to return the number of rows.
The ResultSetMetaData interface provides a method for counting the number of columns but nothing for the rows.
Thanks

No good way before JDBC2.0. u can use JDBC2.0 CachedRowSet.size() to retrieve the number of rows got by a ResultSet.

Hello James!
I do not have any ABAP Instance, only the JAVA one.
Therefore the ABAP transactions are quite useless.
The problem tables are created by people working on the CAF layer.
They have developed and deployed some homemade applications and this is leftovers from their development in some kind of way.
Anyone with any ideas?
Could it be that (yet) some special Portal Dictionary Role needs to be asigned to the Administrator?

How can i know the number of lines in field-symbol internal table

how can i know the number of lines in field-symbol internal table

Hi,
If your field symbol has been defined as an internal table :
Use std describe as
Data: l type i.
describe <fs> lines l.
'l' will contain the number of lines as needed.
FYI
The size of this storage area in a field symbols depends on the number of table lines which is not fixed, but determined dynamically at runtime.
