How many number of lines of code Java File can have?
Hi ALL
Is there any limit on java source file code length?
does more code (say more than 4000 line) impact on performace?
Is there any recomendation on code length and file size?
Thanks
Hi ALL
Is there any limit on java source file code length? There are some (VM) limitations but I have only hit that one when I had some generated code.
does more code (say more than 4000 line) impact on
performace?No, but you probably have a stupid design if you have 4000 lines in one file.
Is there any recomendation on code length and file
size?You should usually only have one top level clas per file, and you should try to have less than 1000 lines in one class.

How to find number of lines in an input file.
Hi,
Can someone tell me, if there is a way to find out the number of lines in an input file. I do not want to read line by line and then count the number of lines read.Then how do you think a program could determine the amount of lines in an input file? How does a human know how many lines are on a page? You're going to have to count the items that separate two lines to know how many lines are in your file.
Either read line by line and count the amount or read char by char and count the number of '\n' occurences instead.
If you have control over writing the input files, however, you can make this better. Write a header in the file that specifies the amount of lines in it. The first line of your file will then hold a number that represents the amount of lines in the file, so you need only read the first line to know how many lines are in your file. -
Total number of lines of code in a class.
Dear Experts,
Given a class, I want to find out the total number of lines of code in all of its methods. Following sub-parts are derived.
1. Find out all the methods of the class
2. Find out the number of lines for each of these methods and finally add the total number.
Can you kindly let me know how I can do this? Thanks a lot !
Best Regards, VikramBe aware that a 2D array is an array of arrays, which don't necessarily have to be the same length. e.g.int[][] a = new int[2][];
a[0] = new int[10];
a[1] = new int[20];
/* a.length == 2
a[0].length == 10
a[1].length == 20*/ -
Apple recently made me change my password which was fine but now it keeps telling me the security code on my visa is incorrect now matter how many times i re-enter it. I can no longer download or update my phone. Please help!!!!
Did you go on-line and fix your billing information? You probably need to do this from iTunes on your computer, not your phone.
If you've double checked your credit card info and it still won't take it, contact your card issuer. -

How to Know the How many number of JCo connections established?
Hi
How to Know the How many number of JCo connections established for mapping?Hi
mConnection = JCO.createClient("001", // SAP client
"<userid>", // userid
"****", // password
null, // language
"<hostname>", // application server host name
"00"); // system number
//Connections to a specific application server (as in the above example)
mConnection.connect();
//Creating the JCO.Client object does not connect to SAP, but a subsequent call to
connect() will accomplishes this
So you can easily find out the number of JCo connections by checking out these.

Being new to iBook publishing I need to know if stats are available to determine how many times my iBook has been downloaded. Can anyone help please? I need to persuade someone that this really is worthwhile. Mr Ignorant.
The only people who can possibly assist you with this is Apple Customer Relations, call your local Apple contact number and ask for Customer Relations then explain your situation clearly and politely (be firm but don't rant).
You might want to investiage what the local laws are regarding defective goods and 'fit for use' definitions on warranties etc. Consumer Protection can be a useful tool to use or bargain with if needed ... -

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. -
No matter how many times I start itunes on my pc I have to agree to the terms of service again and when it does open my settings have all been changed. Why is it doing this and how can I stop it? Reinstalling/repairing does not fix it.
McAfee AntiVirus by any chance? See the thread Why does iTunes delete my itunesprefs.xml?
Or it could be an issue with the SC Info folder. See TS1277 - iTunes: Missing folder or incorrect permissions may prevent authorization for details.
Or a repair install of iTunes from the Programs and Features control panel might fix the problem.
