Hello guys....i have a simple question.
1) How do we use Command Line Interface (CLI) for java programs...i mean we provide arguments using CLI and main() in our java class will use them according to our instructions.
2) Lets suppose that our class has 2 functions Square() and Cube() in it. Now how provide an argument using CLI to one of these functions??
thanx for ur help.....

Your Java program should contain a main function defined as:
public static void main (String argv[])
The command line parameters can then be accessed from the argv array.
As to your second question, you pass parameters to other functions in the call to the function, they do not have direct access to the command line parameters.txtspeak is the realm of 9 year old children, not developers. Christian Graus

Further to Richards answer, you can take arguments when you START or accept INPUT ounce running.
A long, long time ago all programs worked like this:
Loop until input is "EXIT"
Prompt
Get Input
Process Input
When you process the input you'll need to tokenize what is typed and go from there. Enjoy.

Hello Friends
I am in a very critical situation.I am having some float values and the the method I am using to scale is setScale that accepts only vector3d(int,int,int).So how can i create vector3d by using float values.Or is there any other way to create vector3d with flaoting values?
Thanks & Regards

As usual, your question is so vague that it is almost imposible to give an accurate reply. You should really try to give much more information about the context of your question. Here, we don't have any clue what you might be talking about (unless by guessing)...
From which "library" is this vector3d class coming from ? Why are you using float values if you need to express positions in integers and not in float values ? From where are those float values coming from ? etc...

Hello Cedric
I am sorry If my questions are too much vague for you but I try my best to explain from myside.I guess you might be some senior member here so I respect you.Is that reason that some of mine last questions were not answered by anyone?
Actually,I got the answer to my question .but Anyway I will Explain you more in details.vector3d is from java3d Library.And I am getting float values some obj file format.Ans setScale is function of Transform3d.And SetScale are of types, one accepts float and other accepts vector3d.I was getting flaot values so my question was how to create a vector3d from flaot values.
But It solved After more googling.
AnyWay,I appreciate for your valuable time in my thread and even for answering to me .![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

It seems like you are trying to use a Java library for 3D programming. If that is the case, then there would most definitely be a class called FastMath in a package called math somewhere. You can use the FastMath.round(...) method within that class to convert the float values to an int without much overhead. This will enable you to then pass those values to the Vector3D class.
Hope this helps. I would have been of further help if I only knew what libraries you were using.

Thank you Nagy for the quick response.
I was actually looking for a bigger implementation which I could convert to concurrent code for Masters project.I am right now looking into sourceforge to see if there are any projects there..Any suggestions would be appreciated.
Thanks a lot

Hello guys.......im newbie in java. How can we conver a string to integer if it contains more than one numbers like this.......
String str = "12 23 4 35 56 ";
Do you see it has 5 numbers in one string var. How can we do this??
|

Do you need five integers or one. You could split your string, or you could remove spacesLet there arise out of you a band of people inviting to all that is good, enjoining what is right, and forbidding what is wrong: They are the ones to attain felicity.

Hello Friends
I am deleting a file after loading it but some time if any exception occur or some other crash then that file is not deleting bcoz application crashes first.Is there any way to know when application terminates so that i can delete that file or is there any way that will delete my file inspite of any crashes or any other problem?
Any Ideas?
Thanks In Advance.
Regards
Yogesh

If I understand you correctly, the file should be deleletd by the app when it has finished using it but if the app prematurely exits due to an exception then the file does not get deleted.
0. If an exception is being thrown then it should be caught and managed.
1. There should be a single, safe exit point from the application.
2. At start up, can you check for already processed files and delete them? This may be the best solution.

well guys...i did not check this post so i did not know that you wanted my Anser.....OK
Here...if you installed jdk on default location then most probably path for java compiler javac is C:\Program Files\Java\jdk1.6.0_18\bin.This is my path, you use your own.
1....right click the My Computer icon on desktop
2....click the Advanced tab
3....At left bottom, click Envirnoment Variables.
4....Down there, you will find System Variables.....click New.
5....Type variable name Path and variable value ....path mentioned above.click OK.
Thats all.....
what is this all about??.
when you use the command promt then you compile the program using javac...you must set the path first using set path command...now if there, you exit from command prompt, then each time you have to set this path if you use command prompt to compile you program. This method sets that path permanently.
Hope made you clear.
