An easy way to sort a HashMap by Key?

Hi everyone,
Is there any way to sort a HashMap by the key value using API 1.3.1?
Thanks.

Try using a TreeMap implementation instead. It'll maintain the keys in sorted order, as long as they have a Comparable implementation to tell the data structure how to sort them.
If you've written your code properly, it'll be an easy change:
// instead of this
// Map myData = new HashMap();
// use this.
Map myData = new TreeMap();As long as you've used the Map as the reference type it's easy to switch.

Is there an easy way to sort songs by the account it was purchased under?

Hello all, having problems syncing iPods to a family-shared library (over 10GB of purchased music) where I have purchased with two iTunes accounts, my wife has purchased with her account, and three of my kids have purchased with their accounts. There are more accounts than an iPod or iPhone will allow to sync. Since there is no known way to merge songs purchased from different accounts into a single account, I am left to try and sort my library into playlists associated with each purchasing account. Problem- there seems to be no easy way within iTunes to sort music by the account it was purchased under. Is there a way within iTunes to do this? Is there a way with a script (I searched dougscripts and could not find anything relevant)? Is there a way with a UNIX command, like GREP, that I could generate a list and then do something with a script or within iTunes?
Thanks in advance...
Dan

I sent an email to Doug on dougscripts.com. Here is a helpful script he made:

Sort generic HashMap by key?

I have different lists of employees assigned to different projects. This information is contained in a HashMap as shown. I want to sort by the key (project) and then display sorted key (project) and corresponding value (employee list). Any ideas?
Map<Project, ArrayList<Employee>> myMap = new HashMap<Project, ArrayList<Employee>>();
myMap.put(project3, employeeListA);
myMap.put(project1, employeeListB);
myMap.put(project2, employeeListC);

Thank you for your help. I do need to keep the HashMap as a starting point since it's a result of a deserialization.Is it possible to convert existing HashMap into a SortedMap?Ok, as you can see, it's important to list requirements for getting the right solution ;)
As I have no knowledge about how you deserialize the map or how many elements you have, to me, there seem to be two ways to solve your problem:
1. Keep the HashMap and employ a SortedSet (most probably a TreeSet) on the map's keySet, iterate that SortedSet and fetch the values from the orgininal Map.
2. Transfer the original Map to a SortedMap (most probably a TreeMap) and "drop" the original Map.

TS1363 is there an easier way to connect my ipods and phones so that my devices are recognised in my itunes?as i am not ver good with pcs..thanks

i am having trouble with my laptop/itunes finding my devices?i am unable to transfer anything from my itunes to devices as i dont really no what i am doing?is there an easier way to sort this so that my devices can be found and recognised?thankyou

Rather than creating your report directly from a SQL statement use the "Sql Query (PL/SQL Function Body returning Sql Query)" option and re-write your code in PL/SQL. PL/SQL gives you greater control and allows you to test the "null" values and add where clauses to your SQL query based on whether or not a value was selected in the SELECT list.
For example, I have a report parameter screen that has a state drop down list that returns a value of -1 if no state is selected. I can, therefore, code:
IF :P6_STATE_CODE != -1 THEN
query := query + " WHERE state_code = ' ||
:P6_STATE_CODE ;
END IF ;
I have a more complete example if you would like to send me an email ([email protected])

Easy way to remove duplicate songs

After a no of ITunes disasters (most of which I suspect were my fault) I have no ended up with a full library which has a lot of duplicates songs. Being an essentially lazy person is there an easier way to sort them rather than simply displaying the duplicates and deleting one by one

There is a duplicate removal script here:
http://mysite.verizon.net/teridon/itunesscripts/
I doesn't appear to have been tested with the latest itunes although it would probably work OK.
Always backup you files before doing this kind of thing in case you don't like the result.

Sorting a HashMap

Hi everyone!
I'd like to know witch is the best way to sort a hashmap
Let's imagine we've got many people in a place, and this people can build aliances with other people. Every person have an ID (key in the hashmap) and an aliance (value). Does exist any method to sort by value?
I'd like a method that ask me for an aliance and i'd like to return a sortedset of people.
Thanks and sorry for my bad writting!!!!

You want to create a TreeMap, using value as a key.

HT1660 is there an easy way to delete the whole itunes library and and start again. I notice there is only an add file/folder button but no remove facility

I recently upgraded to the iphone 5 and managed to sort the transition out with little trouble but noticed when I tried to put my music on that Itunes has messed with album info and either it or me has generated several copies of the same albums over the years and it makes it quite dificult to sort it all out before reloading on the phone. To stop the chaos I had hoped to clear the library and start again but cant find a way to do it. I was hoping to sort all my music out in original files and consolidate them into a proper folder. HOw do I do this. I notice there is an add fole and folder button but no take away??? is there an easy way?

Use Shift > View > Show Exact Duplicate Items as this is normally a more useful selection. You need to manually select all but one of each group to remove. If you have multiple references to the same files then don't send to the recycle bin. Use my DeDuper script if you don't want to do it by hand. See this thread for background and please take note of the warning to backup your library before deduping.

Is there an easy way to filter a 2-d array based on the values of two of the fields?

Is there an easy way to filter a 2-d array based on the values of one of the fields. In my attached VI the output array has the following format:
TimeStamp        Ident                Frame Type        Bytes    Data
10:57:07.621   3AD00016   CAN Data Frame   8          0000000000000000
10:57:07.622   3AD00017   CAN Data Frame   8          000005E000000000
10:57:07.624   3AD00018   CAN Data Frame   8          0000000003300000
10:57:07.625   2DC00000   CAN Data Frame   8          0000000000000000
10:57:07.626   3AD00019   CAN Data Frame    4         0000030000000000
I would like to delete any rows that do not have an "Ident" between the values of 3AD00000 and 3AD0001E. So for the above data the fourth row would be deleted. The only way I can see to do it is to form a 1-d array. Is there a better approach?
Thank you.
Solved!

Hi chuck72352,
after you have sorted your data, you can use the InRange Function. Combined with a "search 1D Array" you'll get the range you really want.

My itunes library has duplicated all of my music and would take me hours to delete one by one. What is a quick easy way to delete over 2,500 duplicates?

My itunes library has duplicated all of my music and would take me hours to delete one by one. What is a quick easy way to delete over 2,500 duplicates?

Apple's official advice is here... HT2905: How to find and remove duplicate items in your iTunes library. It is a manual process and the article fails to explain some of the potential pitfalls.
Use Shift > View > Show Exact Duplicate Items to display duplicates as this is normally a more useful selection. You need to manually select all but one of each group of identical tracks to remove. Sorting the list by Date Added may make it easier to select the appropriate tracks, however this works best when performed immediately after the dupes have been created. If you have multiple entries in iTunes connected to the same file on the hard drive then don't send to the recycle bin. This can happen, for example, if you start iTunes with a disconnected external drive, then connect it, reimport from your media folder, then restart iTunes.
Use my DeDuper script if you're not sure, don't want to do it by hand, or want to preserve ratings, play counts and playlist membership. See this thread for background. Please take note of the warning to backup your library before deduping, whether you do so by hand or using my script, in case something goes wrong.

Is there a way to sort by artwork??

I'd like to see ONLY the tracks that DO NOT have artwork in a playlist. Is there an (easy) way to do this? Thanks!

Is there a way to sort tracks by whether or not they
have Artwork?
This can be easily done by making a new playlist...
First, check out Apple's page with additional scripts and how to activate this functionally.
Then, check out Doug's AppleScripts for iTunes here for managing Artwork. He has some that will help you find songs lacking artwork and even one that will make a playlist with such. Also if you wish to remove artwork he has a tool for that as well.
To find artwork from say... Amazon... which isn't exactly legal.. search at a download site and you will find one of many utilities available to use.

Is there a way to sort button field names?

In the Button Options dialog box, in the Behaviors tab: Behavior is Show/Hide fields. I cannot figure out ID's method of organization of organizing the field names. Sometimes, the new fields go at the top. Sometimes they go at the bottom... It doesn't appear to be alphabetical, numerical, or chronological. Help!
There also doesn't appear to be any way to sort these field names. My document has about a hundred fields so far, with a couple hundred more to go. Is there any way to sort these names so they are easy to wade through?
If sorting via script is not an option, maybe someone could help me understand the rationale (if there is any) to ID's way of listing field names.
Thanks!

When you say field, do you mean specifically a form field, such as a text field? Or is the information regular text on the page?

Library has been duplicated, duplicates have no file location. Easy way to remove?

Library has been duplicated, duplicates have no file location. Is there an easy way to remove them?
It's a royal ache going through each one, clicking to see if it will play, getting a 'cannot locate the file' message, delete, etc etc.
Showing duplicates just shows I have a lot to tidy up.

The most recent version of the script can tidy dead links as long as there is at least one live duplicate to merge stats and playlist membership to and should cope sensibly when the same file has been added via multiple paths.

External Multi Way Merge Sort in Java!

Hi guys,
some month ago I've sent [this post|http://forums.sun.com/thread.jspa?forumID=31&threadID=5310310] to the Java Programming Forum to notify the availability of an External Multi Way Merge Sort written in Java, tuned and tested over GB of text data and under LGPL license, that can help you in dealing with huge logs or CVS files.
I want here just to notify you about this implementation.
You can run the sorting algo via command line or you can call from any Java class instantiating the ExternalSort class, setting its properties, and calling run().
Searching in the forum I saw many people that ask for an help in sorting huge textual files that doesn't fit in memory. My post solve this problem, but I think that very few people are aware of it :( ....
Hope to help who need this feature. See you!

Nice work this SmallText,
did not try it, but like the idea
I have been doing something similar in c (long, long time ago) and what made our compression really tight for typical csv files was decision to build one huffman coder for each field. The trick was to include field separator symbol into static huffman coder for every field, that provides you with End Of Field signal where to switch to next decoder.
for ExternalSort, I would suggest to make it multithreaded. Having so many many cores and low prices of ram today, it makes a lot sense. Easy way to do it is to have IO_Thread(s) and Worker_Threads (the first ones do read and write and second ones are for sorting).... this is powerfull as you utilize many cores and can easily extend some processing (like compression, token frequency counting or whatever...) via callbacks in each phase (chunking/sorting/merging)
again, congrats, really nice work

Drag the media folder from one over to an open iTunes window. Go away and have a long lunch. Of course if you have a lot of common content you will be spending your next vacation sorting out the duplicates. Oh, you can search the Internet because I am sure somebody has some wonder tool that purportedly prevents duplicates, not that I would trust any automated method. I always deal with duplicates one by one.
Consolidating Multiple iTunes Libraries - http://www.ilounge.com/index.php/articles/comments/consolidating-multiple-itunes -libraries-api1/ - Basically using consolidate/organize to make sure all your media are in one place, then copying media from a second library to the main one by simply adding the media as new files.
