Sorting HashMap based on values

I need to sort a hashmap based on the values, but also need to keep the keys available for retrieving the values.
Example:
key value
1 c
2 a
3 b
Desired Result
2 a
3 b
1 c
Thanks for your help.

You can do this by getting all the Map.ENTRY values in a HashMap object then using a custom Comparator object to sort them by value.
like this:
HashMap hashMap = // your HashMap
Set entrySet = hashMap.entrySet;
/* Now add them into a list and use the Collections
* class to sort them.
ArrayList list = new ArrayList();
list.addAll(entrySet);
Collections.sort(list, yourSpecialComparator);Hope this helps.

Want to sort HashMap based on Values with duplicate values

Hi. I have a requirement to sort the HashMap based on the values not on the keys. My HashMap contains the values which are duplicates. My program is some thing like this.
Map m = new HashMap();
m.put ("Gosling", new Integer(2000));
m.put ("Joy", new Integer(2000));
m.put ("Schwartz", new Integer(3000));
m.put ("Bracha", new Integer(4000));
m.put ("Gafter", new Integer(3000));
still i need to sort HashMap based on the values. How can i do it. I want the output some like this.
Gosling 2000
joy 2000 (may be interchanged)
Schwartz 3000
Gafter 3000 (Same as above)

If you call a function to get the sort order, then just call the function in the ORDER BY clause:
ORDER BY sort_key (city_name)If the sort order is in a table, join to that table, so you can use the appropriate column
FROM table_x x
JOIN cities c ON c.city_name = x.city_name
ORDER BY c.sort_key
user601042 wrote:... i want to display the following order in screen
3 LONDON
1 CHENNI
2 DELHI
4 RIO DEGENEROThe question is, how do you determine that order? I don't see anything obvious in the data itself.
If you were sorting by the id, either ascending or descending, then 1 wouldn't come between 3 and 2.
If you were sorting by alphabetic order, either ascending or descending, then 'CHENNI' wouldn't come between 'LONDON' and 'DELHI'.
If you were sorting by the length of the name, either ascending or descending, then 'DELHI' (5 characters) wouldn't come between 'CHENNI' (6 CHARACTERS) and 'RIO DEGENERO' (12 characters).
By what are you sorting? If you can explain it in English, then someone can help you code it in SQL.

Sorting numbers based on value into arrays

Hi ...
I currently have a large list of numbers inside an array.. say from 0 to 400 000. They appear in order, but are unevenly spaced.
Now I'd like to sort these numbers into arrays.
I want to say: Put all numbers from 0 to 10 into newArray[0]. Put all numbers from 10 to 35 into newArray[1] ....
In the end I need a two - dimensional array with numbers. Is this possible in LabView ? Can it be done in acceptable speed ?
Thank you for your help

While I haven't figured out a way to do this efficiently, the attached
shows a method of doing it number by number. Perhaps the most
efficient may be to insert Matlab code and use a sort function, or
equivalent in c.
To use this to sort multiple numbers, put inside a for loop and build up an array. (also see attached).

Sorting the list of value like in BEX but out of crystal report

All,
I have created a crystal report base on a BEX query where I have a variable for which i am filtering base on a field period.fiscalyear.
for the list of values that prompt you for this variable ...
l in BEX we can do the sort by either alphabetical ascending order or descending alphabetical order such as:
here is for ascending
001.2008
001.2009
or by clicking on it we can do the following: (descending)
012.2009
012.2009
however in crystal when refreshing the report in infoview it sorts the list of value base on the month
something like this :
JAN 2008 [0FISCPER].[K42008001]
FEB 2008 [0FISCPER].[K42008002]
We would like to have in crystal the same behaviour than in BEX, so in crystal we would like to be able to get the list of values sorted in either ascending order to descending order. is there a way to do so ?
notes also that we would like to avoid to create the variable in crystal
Philippe

Hi,
in Crystal Reports you have per InfoObject - depending on the definition - the key value, the description and the member unique name. In BW these objects are defined as NUMC in most cases - which means it is a character / string.
In your example the value is 001.2008 and 001.2009. What you can do in Crystal Reports is to split up the values into year and month and then sort based on the actual numbers.

How to create a new row for a VO based on values from another VO?

Hi, experts.
in jdev 11.1.2.3,
How to create a new row for VO1 based on values from another VO2 in the same page?
and in my use case it's preferable to do this from the UI rather than from business logic layer(EO).
Also I have read Frank Nimphius' following blog,but in his example the source VO and the destination VO are the same.
How-to declaratively create new table rows based on existing row content (20-NOV-2008)
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/13-create-with-params-169140.pdf
I have tried:
1.VO1(id,amount,remark1) and VO2(id,amount,remark2) are based on different EO,but render in same page,
2.Drag and drop a Createwithparams button for VO1(id,amount,remark),
3.add: Create insertinside Createwithparams->Nameddata(amount),
4.set NDName:amount, NDValue:#{bindings.VO2.children.Amount}, NDtype:oracle.jbo.domain.Number.
On running,when press button Createwithparams, cannot create a new row for VO1, and get error msg:
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: For input string: "Amount"
java.lang.NumberFormatException: For input string: "Amount"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
Can anyone give some suggestions?
Thanks in advance.

Hi,CM,
I'm really very appreciated for your quick reply! You know, today is Saturday, it's not a day for everyone at work.
My principal requirement is as follows:
1.select/check some rows from VO2, and for each selection create a new row with some attributes from VO2 as default values for VO1's corresponding attributes, and during this process the user may be cancel/uncheck or redo some of the selections.
--so it's better to implement it in UI rather than in EO.
2.it's better to implement this function with declarative way as in Frank Nimphius' blog.
--little Jave/JS coding, the better. I only have experience in ORACLE FORMS, little experience in JAVA/JS.
In order to get full information for the requirements of my use case, can take a check at:
How to set default value for a VO query bind variable in a jspx page?
(the end half of the thread: I have a more realworld requirement similar to the above requirement is:
Manage bank transactions for clients. and give invoices to clients according to their transaction records. One invoice can contain one or many transactions records. and one transaction records can be split into many invoices.

N9 Photo Gallery sort order - based on what?

Hello,
I am thrilled with my N9, but have one problem: I want to use the phone to keep not only photos made with it. I therefore saved extra photos in the Pictures folder. They appear in the gallery, but in a weird order, not based on either the name, EXIF date, modification date or creation date. Is there a possibility to sort them on either of these? All I want is to control the sort order. After all, it is MY gallery...
On my previous phone (N8) sorting was based on the last modification date. Also not optimal (EXIF date would have been perfect) but still controllable.
Solved!
Go to Solution.

Well, maybe those pictures were never edited outside the phone, I don't know.
Anyway, I believe I found the explanation: I exported the photos from Picasa, maxing them to a resolution of 1600xXXX. This way all files were created... today. Nevertheless the EXIF information is correctly saved by Picasa, so Date Image Taken was preserved. Although I modified in all files the creation date to be equal to EXIF Date Image Taken (ACDSee/batch/AdjustTimeStamp) , and then also renamed all pictures based on that, the "new" creation date still remains saved somewhere in the picture files and the Gallery sorts the pictures on it! The pictures were sorted in the reversed order I exported them from Picasa... Bad.
Anyway, since this is not a request forum, it would be futile to say (again) that Nokia should use the EXIF Date Picture Taken for picture sorting. So I don't say it (!).

Hi,
Using OVS you can achieve this., In OVS Event Handler read the value based on which you want to display F4 for other field and populate the values based on the first field.
this link is fine., go through this: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/606288d6-04c6-2c10-b5ae-a240304c88ea?quicklink=index&overridelayout=true

How to generate controls dynamically based on value stored in database using mvc4?

In my database, i have a field called control_ids corresponding to text box, dropdownlist, radiobuttonlist etc. My goal is to
create controls dynamically based on value of control_id-field in table. Anybody please help me how to create the controls dynamically in MVC 4 for this scenario.

In your view you could do something like that:
foreach (var field in Model.FormStruture.fields)
<div class="editor-label">
<label for="@field.Name">@field.Descricao</label>
</div>
<div class="editor-field">
<input class="text-box single-line" id="@field.Name" name="@field.Name" type="text" value="@field.Valor" data-rules-required="@field.Mandatory.ToString().ToLower()" data-rule-number="@field.Tipo.Equals(SiB.OCR.Documentos.Modelo.TipofieldDocumento.Numerico).ToString().ToLower()" title="@field.Descricao" />
</div>
if (!String.IsNullOrEmpty(field.Format))

Calculate BED & relevant duties based on value @ PO for a particular vendor

Dear experts,
Is it possible to calculate excise duties and other relevant pricing elements at purchase order level based on VALUE and capture the same (part1 - MIGO and part11-J1IEX) for a PARTICULAR VENDOR INVOICE?
The business process is like this. First we r receiving invoice from vendor and based on that we r creating PO and do other transaction activities.
We r using ECC6.we r maintaining tax details through tax codes based on percentage and pricing procedure(TAXINJ) is activated and pricing elements are managed through cond.types(gross is value base and others are managed by %).
I find difficulty to capture excise data (cin) through % in j1iex and manual value adjustment is tedious process for multiple line items.
If it is possible, kindly suggest.
Regards,
Vimalan.

This is nothing but Trading process...
u will not know what amount of excise the vendor is passing on u..
just follow the below steps
hi
create material master with HAWA material type..
maintain material chapter id combination in J1ID
create tax code with zero excise and some vat/cst in FTXP
maintain condition records for tax code in FV11
Assign tax code to company code in tax on goods movement
create PO in ME21N with the tax code created.
During MIGO change the base amount
Base amount = Base amount(PO) - Excise(bed, ecess, secess)
enter the bed ecess secess in excise item details
In excise header tab click on additional data (pencil icon) there in miscellaneous tab check mrp indicator
post the document.
in MIRO change the base amount to base amount - excise.

Convert hashmap (containing null values) to hashtable

hi
the following code gives me java.lang.NullPointerException
how can i convert a hashmap ( contaiing null values ) to hashtable... ??
and vice versa ?
          HashMap hm =new HashMap();
          hm.put("1","one");
          hm.put("2","two");
          hm.put("3","three");
          hm.put("4",null);
          Hashtable ht = new Hashtable(hm);how ever the code will run perfectly well if i remove
               hm.put("4",null);Regards
Lav

so does that mean that theres is no way to convert a
hashmap containing null values to hashtable ..!!There are several ways described above.
If you mean is there a way to preserve the nulls as nulls, then, no, you cannot do that, because, as stated in the docs, null cannot be a key or value in a Hashtable.

XML Forms Builder: Sorting news based on a date field in a XML form

Hi Experts
I have a requirement and I am stuck up in finding a solution. I have a XML form and this has been mapped to a folder in KM. It publishes news. In the collection renderer settings there is an option to sort the news ascending or descending based on created/modified criteria.
The requirement is to sort the news based on a date field in XML form. Can you experts help me in getting the solution for same?
The users who post the news in our portal needs the information to be sorted based on a date field shown.
Thank you
Best regards
