How do I convert the unicode into an int?

I have to take a large integer from user and put each digit into an array. To take the large number I use .nextLine() so that I would be stored as a string. Then I put each digit into an array of type int, and I use implicit type casting to convert each character to an int. The problem is that now the array contains the unicode for the number, how do I get the actual number?
I know this is kind of silly not to use bigInteger but that's part of the assignment.
better yet, the array mas as well be of bytes since no digits Unicode goes above 57

So your character is '1' and when you cast that to an int you get something like 49? And you want 1 instead? If that's the case then don't cast, use Character.getNumericValue('1') instead. But read the documentation for the method so you don't get surprised at what Character.getNumericValue("L") returns, for example.

here are my program.
please help me to convert it into modular program by using below method and constructor.
1)valueIn():fill in the array by generating random number between given range.range is given by user.
2)valueOut(): to display all the value in the array.
3)total():calculate total of all the value in an array.
4)arrange():sort the number.
5)findOur():to display the frequency of the number.
6)rangeOut():user give a range aggain to display all the number between the given range.

Idon't think it is fair to have us do what looks to be your homework. The problem is fairly simple, why not take a stab at it and let us comment on it?

How can i convert 3d movie into 2d to watch it in mac

i have a movie with mkv file playable on vlc how can i convert the movie into 2d

There are now a bunch of them out there. Do a Google search for "mac 3D conversion" They tend to be around $35. I have been using iSkysoft products, which have been fairly easy to use. They have a "iMedia Converter Deluxe for Mac" that besides the 3D to 2D conversion, will also convert video to 70+ formats, has a 1-Click Video Downloader, and a single click Rip DVD and Burn to DVDs feature. Also claims to be "Ultrafast" all for the same price others apps are that only do the conversion.

How can I convert the ringtone (m4r file) I made into an mp3 file on itunes?

How can I convert the ringtone (m4r file) that I made into an mp3 file on iTunes? I want to put it on a CD, but I can't figure out how to convert it. I didn't buy it, I made it by converting a YouTube video into an mp3 (I wanted to get the little song in the video for a ringtone.) I'm not sure what to do.

Hello ed2345,
Thanks for the help, but this is not the problem.
It's hard to describe the problem, but I'll try it again, this time with pictures.
I was left with the following folders in the iTunes Downloads folder.
http://www.picfront.org/d/7yb3
These TMP Folders have a download.m4a and a Info.plist file.
After moving the audio files in iTunes a bit I get this.
http://www.picfront.org/d/7yb2
As you can see no other Information for the download.m4a than the length.
That's how the .m4p file looks like
http://www.picfront.org/d/7yb1
And this is how the same .m4a file currently looks
http://www.picfront.org/d/7yb0
Like I said, I could edit all these download.m4a files by myself but that would leave some information out.
Note: Sorry, I hope the links do not spam you with annoying ads. I don't get any but I was told that there can be some annoying one.

How can I convert the download.m4a and Info.plist into the right audio file

The topic is actually the problem that I have.
I have bought music and it was downloaded successful (all of it) but iTunes had a strange freeze while converting the files into the right audio file. Some files were converted but after the freeze no more.
I'm now left with these .tmp folders in the downloads folder which have the download.m4a and Info.plist files.
My iTunes is able to play these download.m4a files, but they show no information and covers and this is really annoying. I could write and change it all by myself, but than I would still miss some information (and covers).
Is there any way for me to convert or combine these files?
Note: I'm not able to restart any downloads, because they were successful.

How can i convert the firefox-history-timestamp in places.sqlite into a normal date format? The firefox-timestamp is not equivalent to the unix-timestamp, that's why I ask. I could not find a conversion function. Does anyone know something about this?

As I opened the places.sqlite with an sqlite-editor I found out that firefox saves the last_visit_date via a timestamp which is 16 digits long. I realized that the first 10 digits are similar to the corresponding unix-timestamp but not equal. So.. how can i convert the firefox-timestamp into a normal date? Or into the corresponding unix-timestamp?

Write a bash script or 'C' program to change the date format and then use the sql update function to receive the stdio output 'where date_field='embeded date value'.

I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?

I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?

The application Acrobat provides no language translation capability.
If you localize the language for OS, MS Office applications, Acrobat, etc to the desired language try again.
Alternative: transfer a copy of content into a web based translation service (Bing or Google provides a free service).
Transfer the output into a word processing program that is localized to the appropriate language.
Do cleanup.

How can I convert DVD- video into Apple's format so that it can be played and streamed from my Mac?

How can I convert DVD- video into Apple's format so that I can play the content on my Mac and also stream it to my Apple TV? A few years ago, I transferred all of my home videos onto DVD but now would really like to put these onto my Mac and stream them through Apple TV to watch on the "big screen". Any advice would be most welcome!! Thanks

MPEG Streamclip.
Apple do not have their "own" format. You need to convert your DVDs to H.264 though.

I have a 2 page PDF (portrait format), how can I convert the format to landscape?

I have a 2 page (portaait format) PDF file how can I convert the PDF file into landscape format before I change it to XL?

Hi jsremick,
To change the page orientation of a PDF, you need to use Acrobat. (Reader allows you to rotate the page view, but not the pages themselves).
If you don't have Acrobat, feel free to give it a try. You can download the free 30-day trial from http://www.adobe.com/products/acrobat.html.
Best,
Sara

What version of Acrobat are you using?
You might need to go to File> Save As Other> Microsoft Word or choose 'Adobe PDF printer' from the File menu.
Is save as option not functioning correctly? Do you get any specific error?
Please let me know.

How do I convert à PDF file into my dairy?

How do I convert à PDF file into my dairy?

If I understand whatnyounare asking (and not sure I do), you may have a difficult time accomplishing that. Calendar app doesn't store documents and I don 't know of an app that will extract text from a PDF and place it in a calendar entry automatically. Check the app store - I could be wrong - but you will have to handle that manually.
Many apps that read PDF will allow you to copy text, including GoodReader mentioned above.
