Object sorting

Hi,
My poject need the sorting function according to one attribute of a object. but the attribute is varied by the selected list item on the user's interface, and we want to create a common function to this. It's diffcult to me now. can anyone give some advice ?
Thanks in advance.
Regards,

holly_xin,
You could create a set of objects which implement java.util.Comparator, one for each attribute you can search on. This is then passed to your sorting function which can then use any number of sorting methods (e.g. java.util.Arrays.sort()) to sort the objects.
Another option is to use a single Comparator which uses reflection, a case switch or any other other selection mechanism to determine the attribute to sort.

How do i create a Object & Sort.

Sorry . This is a post of the same question as the replies on the last thread seems not enough to let me carry on the next step to finish a project.
Firstly => I am creating a ranking page .
The records is record in Summary.txt as followed :
[playername,numberOfAttempts]
bravo1,3
1234567,3
woshibao2,5
This record is as can be seen , first is playername follow by numberOfAttempts.
I am trying to do a Top 10 Ranking base on the[b] LEAST attempts to win will be ranked the highest.
Many people told me that i can use Array[].sort in my previous thread.
However, firstly i will need to break the playerName and numberOfAttempts into 2 parts which is
StringTokenizer st = new StringTokenizer(brInFile.readLine(),",");
String playerName = st.nextToken(); // the use of string tokenizer.
String numberOfAttempts = st.nextToken(); But how do i create a ARRAY / OBJECT that can
SORT base on numberOfAttempts , then get Back the PlayerName and then i will use this information to be display on my ServerView.
Array cannot contain String , when i use StringTokenizer to break my records , by default the output will be string ? How would i able to rank by String or i should maybe convert by Integer.parseInt ?
Sorry , i am quite confused. Hope i can get some help.
[ Hope i can get some codes help or samples ]
i readed the API but i still not sure how to create the Object or etc..

Firstly , how do i hold all the datas .
What Object or Array should i use to hold the
playerName and numberOfAttempts.You don't know what a class is?
class Car {
    String make;
    int yearOfManufacture;
    int capacity;
    int vin;
    // etc
    // constructor(s)
    // methods
Secondly , i not sure about the "Comparable
Interface" .Read about it in the API. Experiment with some simple test code. If you still don't understand, post your code here and ask a specific question. At the moment you problem is "I want to build a space craft but don't know how. Can you show me?" Way too broad.
Thirdly , how do i write code that determine how i
order the objects.. hahaSimple. You compare the number of attempts and return an appropriate value.
Sorry , i hope someone will post a sample code on
that class :)Nope. It's not our work. It's yours. You write the code.
Sort => Then Obtain back player Name then able to
Display . even on a System.out.printlnwould be fine.Once you have the rest done, do as others have told you, call Arrays.sort which will sort your array for you. You can then loop over the array and print the details.

ReportDocument object, sort options

I am using Visual Studio 2005, Visual Basic syntax, SqlServer 2000 and CrystalReports XI to build a Windows Forms application. I have a form that allows the user to define criteria for a report which I pass as a parameter to a ReportDocument object. I now want to allow the users to define the sort fields also. But it appears that the sort fields of the object are readonly. Can I define the sort fields of the ReportDocument class in my code?

Well, I thought my question was answered. It was a very good example. But.... I want to allow the users to select more than 1 field to sort by. I have created the following function and it works if I only have 1 item, but it fails on the 2nd item if I have more than 1. Can you sort by more than 1 item?   And also, it is breaking to a new page for every new last name (my sort), is there a property I need to set so it does not do that? Thanks for your help.

Regarding ArrayList objects sorting

I have number of class instances to be stored in an ArrayList say for example, I have one employee class which has empname,empno,designation as columns.
I am adding this class instances into the ArrayList. I have an another class which has a method sorting() to sort this ArrayList object with 3 parameter . My ArrayList object is the first parameter passed to this
sort() method based on anyof the column names specified as second parameter along with ascending or descending as third parameter my object has to be sorted.
Is there any compatible way to sort the arrayList by the above requirement. Kindly guide us for further proceedings.

ar.add(new Emp(7, "shiva", "27-Oct-2005 09:08:28 AM"));
ar.add(new Emp(1, "raj", "29-Aug-2005 11:15:07 AM"));

Writing a function to that sorts any object

I am trying to write a function that sorts any type of array of objects. For example, I want to call
NewArray = exampleclass.sort(ObjectOfAnyType).
The sort function has to return a new array. I have run into two errors, however.
Error #1
as3.java [21:1] cannot resolve symbol
symbol : variable Object
location: class as3
if (Object instanceof Comparable)
^
Error #2
as3.java [25:1] incompatible types
found : java.lang.Object
required: java.lang.Object[]
Object [] rtn = obj.clone();
*** Below is my source code ***
import java.*;
public class as3 {
/** Creates new as3 */
public static Object sort(Object [] obj)
 if (Object instanceof Comparable)
 if (Object instanceof Cloneable)
 Object [] rtn = obj.clone();
for (int i = 0; i<obj.length-1; i++)
for (int j=i+1; j<obj.length; j++)
if (rtn.compareTo(rtn[j]) == 1)
Object [] tmp = rtn[i];
rtn[i] = obj[j];
rtn[j] = tmp;
else
throw new ObjectIsNotComparableException("Object not comparable");
Any help appreciated. Thanks!

Changing from "Object" to the name "obj" fixed the
statement:
if (obj instanceof Cloneable) but not if (obj
instanceof Comparable).
I don't know what's causing this one yet... worry about that in a sec
I am also getting one new error now:
as3.java [28:1] cannot resolve symbol
symbol : method compareTo (java.lang.Object)
location: class java.lang.Object
if (rtn[ i].compareTo(rtn[j])
This one is because rtn[ i] (and rtn[j]) is an Object, which has no method compareTo. Try casting it to a Comparable...
I think I just worked out why it let you go with the cloneable, but not with the comparable. obj is an array, and sure an array is cloneable, but how could you compare an array? Sure you can compare the elements in the array... So either check if obj[0] instanceof Comparable, or drop the test all together.
Note: checking obj[0] will give you an exception if someone asks you to sort an array of 0 length (no elements)
Hope this helps,

Sorting transient attributes

Does anyone know how to take advantage of adf/uix built in sorting for view objects that contain only transient fields? For example, when I build a view object that references an entity object, sorting (via a uix table tag) works great. However, when using a view object with only transient attributes, sorting does not work through a uix table. Any ideas would really be appreciated...

FYI,
I've figured this out for anyone that sees this post in the future. Here's how to do it.
1 Open the transient view object in the view object editor (by double-clicking on the view object).
2 Select Java.
3 Press the Class extends button.
4 For Object, browse to the following class: SortableTransientViewObject (see below for implementation)
5 Press OK.
6 Select Attributes.
7 For each attributes:
1. Select the "Selected in Query" property.
2. Copy the exact name of the attribute to the query column alias field.
8 Press OK.

Regardig Authorization object

Hi All,
I would like to know the step by step creation of authorization object...
Iam able to create the authorization class and objects using SU21 for a ztable fields..
And am not getting how to use this in ABAP program.
I know using Authority-check we can do this...
Here Iam not understanding to whom we are checking the authorization..and how...
And also is this necessary to create a role in pfcg and assign it to user...
if so what is the necessary to create a role...
and what is the link between SU21 and pfcg...
how this is affecting...
can any one help me...out of this...
thanks and regards

Go through this
For example:
program an AUTHORITY-CHECK.
AUTHORITY-CHECK OBJECT <authorization object>
ID <authority field 1> FIELD <field value 1>.
ID <authority field 2> FIELD <field value 2>.
ID <authority-field n> FIELD <field value n>.
The OBJECT parameter specifies the authorization object.
The ID parameter specifies an authorization field (in the authorization object).
The FIELD parameter specifies a value for the authorization field.
The authorization object and its fields have to be suitable for the transaction. In most cases you will be able to use the existing authorization objects to protect your data. But new developments may require that you define new authorization objects and fields.

AUTHORITY-CHECK OBJECT object
ID name1 FIELD f1
ID name2 FIELD f2
ID name10 FIELD f10.
Effect
Explanation of IDs:
object Field which contains the name of the object for which the authorization is to be checked.
name1 ... Fields which contain the names of the name10 authorization fields defined in the object.
f1 ... Fields which contain the values for which the f10 authorization is to be checked.
AUTHORITY-CHECK checks for one object whether the user has an authorization that contains all values of f (see SAP authorization concept).
You must specify all authorizations for an object and a also a value for each ID (or DUMMY ).
The system checks the values for the ID s by AND-ing them together, i.e. all values must be part of an authorization assigned to the user.
If a user has several authorizations for an object, the values are OR-ed together. This means that if the CHECK finds all the specified values in one authorization, the user can proceed. Only if none of the authorizations for a user contains all the required values is the user rejected.
If the return code SY-SUBRC = 0, the user has the required authorization and may continue.
The return code is modified to suit the different error scenarios. The return code values have the following meaning:
4 User has no authorization in the SAP System for such an action. If necessary, change the user master record.
8 Too many parameters (fields, values). Maximum allowed is 10.
12 Specified object not maintained in the user master record.
16 No profile entered in the user master record.
24 The field names of the check call do not match those of an authorization. Either the authorization or the call is incorrect.
28 Incorrect structure for user master record.
32 Incorrect structure for user master record.
36 Incorrect structure for user master record.
If the return code value is 8 or possibly 24, inform the person responsible for the program. If the return code value is 4, 12, 15 or 24, consult your system administrator if you think you should have the relevant authorization. In the case of errors 28 to 36, contact SAP, since authorizations have probably been destroyed.
Individual authorizations are assigned to users in their respective user profiles, i.e. they are grouped together in profiles which are stored in the user master record.
Note
Instead of ID name FIELD f , you can also write ID name DUMMY . This means that no check is performed for the field concerned.
The check can only be performed on CHAR fields. All other field types result in 'unauthorized'.
Example
Check whether the user is authorized for a particular plant. In this case, the following authorization object applies:
Table OBJ : Definition of authorization object
M_EINF_WRK
ACTVT
WERKS
Here, M_EINF_WRK is the object name, whilst ACTVT and WERKS are authorization fields. For example, a user with the authorizations
M_EINF_WRK_BERECH1
ACTVT 01-03
WERKS 0001-0003 .
can display and change plants within the Purchasing and Materials Management areas.
Such a user would thus pass the checks
AUTHORITY-CHECK OBJECT 'M_EINF_WRK'
ID 'WERKS' FIELD '0002'
ID 'ACTVT' FIELD '02'.
AUTHORITY-CHECK OBJECT 'M_EINF_WRK'
ID 'WERKS' DUMMY
ID 'ACTVT' FIELD '01':
but would fail the check
AUTHORITY-CHECK OBJECT 'M_EINF_WRK'
ID 'WERKS' FIELD '0005'
ID 'ACTVT' FIELD '04'.

The first line of file50.txt contains the number of id/inventory integer pairs listed on subsequent lines. The idea behind the data type item is the simulation of an item in a store, nearly all of which use a bar code for identification purposes. For every item in a store we keep track of an id value and an inventory amount. So file50.txt looks like this:
50
3679 87
196 60
17914 12
18618 64
2370 65
etc. (for 45 more lines)
Each id value in file50.txt will be unique.
Assignment:
Write a program that solves the following sequential events:
loads the data file, file50.txt, as a collection of Item types maintained in a Store object
sorts the data using quickSort
prints the data , now in increasing order based on the id field of an Item object
The printing should add a blank line after every 10 items in the output. Include a line number in the output. For example:
Id Inv
1 184 14
2 196 60
3 206 31
4 584 85
5 768 85
6 2370 65
7 3433 5
8 3679 87
9 4329 64

11 6265 58
12 6835 94
13 6992 76
14 7282 73
15 8303 90
16 9267 68
etc.
You will need to complete the getId(), getItem(), compareTo(), equals() and toString() methods for the Item class.
You will need to complete the Store() constructor, displayStore(), loadFile(), quickSort() and toString() methods for the Store class.
That's the assigned project.
this is a side story. I'm a highschooler, and my teacher always hangs out on the internet, teaching nothing. and like this, he just print some problems from the internet and give it to the students. is there a handout about lesson? no. is this always been like this? yeah...
I have no idea how to right a method called getId(), getInv(), etc...
would anybody please... please help me?

Well along with the F coming to you for your little assignment I also give you an F for creative writing. This is a shoddy attempt. Why not try something new. Like I live in a mountain town and could not get to school to attend class for three weeks because an avalanche closed the pass.. or my cat peed on my keyboard and I had to get a new one but I couldn't afford it so I don't have enough time left now to figure out myself.
I dunno. Lot's of ideas.
Nobody cares about your little sob story. If your teacher is in fact this bad then you should have taken it up with the school administration long ago. It might not be too late to do so. But truth or not it's not going to sucker somebody in to doing your homework for you.
If you want to learn then do the tutorials until you are capable of completing the assignment. If you have specific questions then help can be given. I don't know what I'm doing is NOT a specific question.

Somebody please help me for sorting arrays!!

well you're really going to have to at least do a quick skim of:
http://java.sun.com/docs/books/tutorial/getStarted/index.html
And also how to use a browser and browse the API Docs
especially for: Comparable
You'll also get flamed for just posting a Homework assignment with no evidence of your own attempts to solve it, OR for not formatting the code with
[ c o d e ] [ / c o d e ]
I suppose you get some points if you answer some of the questions?
Try the easy parts first:
Complete the methods of the class Item
Ignore the deliberate Typos in the assignment
see how you have the class members defined already like:
private int myId; // The guy couldn't be bothered to document his code
private int myInv; // So you will have to.......document itlook at this:
public int getId() {}As it is the compiler will just say : Missing method body, or declare abstract...
Your job is to guess what it should do from the 'signature'
It must return an int and that should be related to Id neh?
So try things like:
 @return the value of the myId field.
public int getId()
 return this.myId; // return myId would do as well
 Sets the value of myId field
 @param newId the new Id to set.
public void setId( int newId )
 this.myId = newId; // the old value is replaced with the new
}do the rest of the simple obvious methods.
You will get some marks and improve your confidence with simple Java
Read The API doc on Comparable Interface:
Decide Carefully how you want to "Order" Objects of type Item.
In this case this will probably depend first on myId and then subsequently on myInv
The Comparable interface helps Sorting methods decide qhich object comes first when sorting.
you will need ssomething like this.
 Implements Comparable - Read the API
public int compareTo( Object o ) throws ClassCastException, NullPointerException
 if( o == null )
 throw new NullPointerException("Blah blah blah");
 if( !( o instanceof Item ) )
 throw new ClassCastException("Apples and Oranges!");
Item item = ( Item ) o; // Cast o to an Item so it can be checked
if( this.getId() < item.getId() )
 return -1; // Signal that "this"is less than o
if ( this.getId() > item.getId() )
 return 1;
// here both items have the same myId field
if( this.getInv() < item .getInv() )
 return -1;
if( this.getInv() > item.getInv() )
 return 1;
return 0; // they are at the same sort order
}You use that method like:
Item a;
Item b;
if( a.compareTo( b ) < 0 )
 //blah blah
}To write the equals method read the API it is similar to compareTo()
To Read The file : Search on this forum for reading a file line by line.
Check the API.
ALso if you have installed Java:
There are many examples of how to do this in the demo directory
Even one on QuickSort ---
So plug away..................

First of all I found out that when I set the column's header like this:
columnNames_vector.addElement("<html>Column 3 Second Row</html>"); //In the setupGUI() methodthe TableHeight_ColumnWidth.determineColumnWidth(TableColumn col, FontMetrics fm) method calculates the column's width by counting <html>, </html>, characters as well. So I added a check to reject these characters and not count them for the column's width.
As for the header's height:
I found that when the first column's header is set to display two-lines, then the height of the rest columns headers is set to display two-lines as well. In other words, the height of the first column's header affects the height of the whole JTableHeader.
I found that the BasicTableHeaderUI.getHeaderHeight() method is called, within which there are these comments:
 // If the header value is empty (== "") in the
 // first column (and this column is set up
 // to use the default renderer) we will
 // return zero from this routine and the header
 // will disappear altogether. Avoiding the calculation
 // of the preferred size is such a performance win for
 // most applications that we will continue to
 // use this cheaper calculation, handling these
 // issues as `edge cases'. Should I override a class and if so which one? I am so confused! If anyone has any idea about how to set the header's height according to the cell's height that is the maximum among all, please let me know.

Appending data in ranges object

hi,
i have a ranges field i want to append the land data in
ranges object.

sort table itab by vbeln posnr.
read table itab index 1.
ranges-low = itab-vbeln.
clear itab.
describe table itab lines w_line.
read table itab index w_line.
ranges-high = itab-vbeln.
ranges-sign = 'I'.
ranges-option = 'BT'.

"Bounce" objects in Motion 5?

Hey everyone,
I am trying to make an intro like this one: http://www.youtube.com/watch?v=7yVM3fGiJrs
And I was wondering how you could make the objects sort of "bounce" instead of just coming to a stop.
The obvious answer it just to keyframe it going further up than you want it and then keyframe it going back down, but I don't think that would be a very convincing bounce.
Any help is appreciated!
Thanks,
Adam

Group the objects that will bounce together. Add a Gravity Behavior to their group. Enclose that group in another group (select the group and type Command Shift G). Add an Edge Collision behavior to the "parent" group. Adjust the Height parameter to bring the bounce off the bottom edge of the canvas (if needed.) Adjust the Bounce Strength to about 40%. Adjust the Acceleration of the Gravity behavior to around 1000 (to start) and move the bouncing group above the canvas by about twice the distance it needs to travel (you might have to slide the behavior starts to before the start of the project to assist in timing the "entry" of the bouncing objects into the "scene"; and extend the out points of the behaviors to the end of the project so once the objects come to "rest", they'll stay in place.) Edge Collision + Gravity can provide a quite realistic bounce effect.

Sorting properties from get-mailbox on a single mailbox, how?

get-aduser username -Properties * gives a nicely sorted list of the properties for a user's AD account.
get-mailbox username | fl * gives a nicely
unsorted list of the properties for a user's Exchange mailbox.
Anything more elegant for sorting the get-mailbox output?
Get-Mailbox username | fl * | Out-File -FilePath c:\username-mailbox.txt
Get-Content C:\username-mailbox.txt | sort
What is the technical terminology for the type of output produced by get-mailbox username?
Thank you for your time, Joe

Hear ya Bill. But I'm only returning a single PSObject (Microsoft.Exchange.Data.Directory.Management.MailEnabledOrgPerson), and I'm attempting to sort the properties on the single object. Sorry I'm not explaining this well.

unlimited
beon                  beon                  exchange03   unlimited
Not a problem to sort: get-mailbox | sort alias
Output from: get-mailbox someuser

IsMachineToPersonTextMessagingEnabled : True

I'm not sure what to sort on... I've tried just: get-mailbox someuser | Select-Object * | sort
The output looks the same as output from: get-aduser someuser
This doesn't work either: get-aduser someuser | sort -descending
Thank you, Joe

Sort element inside JComboBox

Hi,
i have a JComboBox containing list of Strings
so lets say:
String[] test = {"omega", "alpha", "beta", "Arc"}
JComboBox testing = new JComboBox(test);
now is there a way to sort the elements inside the JComboBox once they have been inserted ? or anyone know how to sort the elements before putting them in inside JComboBox ?
the sample code was just for testing and I am dealing with MANY elements (at least 10) inside the JComboBox
thanks in advance
if you have any links that helps with this topic, I will also appreciate it

<hmm>
1) Check out the [url http://java.sun.com/docs/books/tutorial/collections/index.html]Collections API
2) Note that using a java.util.Vector, (which combo box accepts in its constructor), allows you to do
one of two things:
............If you are using a custom object, have it implement Comparable
............If you are using flat Strings, never mind...
Then calling java.util.Collections.sort(myVector) would do this for you. NOTE: by not implementing
Comparable, this may have undesirable results....
A number of collection objects sort by default when you add an element.....

Online test questions... plz provide answers
