Comparing Two Jtree Objects

Hi
I had constructed two JTree objects. Now i want to find the difference between these two JTree's Node wise.I dont have any idea how to proceed further.If some one help me in this regard i would be very thankful.

The JTree component handles the 'view' side of things. The actual data it displays is held in a TreeModel. You can create your own and pass it to the JTree when you create it otherwise a DefaultTreeModel is created for you by the JTree.
What I'm getting at is that to achieve your aim you want to compare the TreeModels rather than the JTrees.
If you haven't created your own, you can get it from the JTree using jTree.getModel()
Calling methods on each model and comparing the results will achieve your aim.

Compare two Java Objects without Comparable / Comparator

Hi Friends,
I would like to compare two java objects (lots o attributes) without using Comparable / Comparator.
Any suggestion/sample code would be helpful.
Thanks,
Sachin

I suppose you could design another feature to compare Objects... but that would involve a design process, so asking for sample code is definitely premature. And as EJP says, what would be the point?
At least that's what I would answer if this was one of those stupid interview questions.

Compare two similar objects

Do you know about any possible Java bugs with JDK update?
In my case, my code stopped working.
Here is what I have. There are two similar objects, but Object 1 has key, and Object 2 (same as Object 1) has no key. I need to compare both, and if they are equal, I need Object 1 to assign key to Object 2.
It worked before. How I can get around.
Please help me if you can.
Respectfully,
Alex

Let me change the question:
"Can we compare two objects one with key and another one without key? How?

How to compare two database objects?

Hi,
I need to compare two objects with embedded objects/collections in it to tell exact difference between the two.
e.g.,
create type t1 as object (name varchar2(10), age number);
create type t2 as table of t1;
create type t3 as object (user t1, family t2);
... and so on.. this type hirarechy is big in my case..
I want a procedure/function which can tell me what and where is the difference.
PROCEDURE (obj1 T1 , obj2 T1) IS
BEGIN
END;
e.g., t1.name = 'John' and t2.name = 'Mich' then it should return t1.name etc..
Is it possible?
Thanks

Why a new thread?

How to RELIABLY compare two File objects?

Hi java community!
I have two File objects and I need to know whether they both point to the same file on the system. First, I tried using the equals() method of the File object, but later I found that this often returns false even when file being pointed to by both objects is the same file.
For example:
public static void main(String[] args) throws Exception {
    File mFileA = new File("C:\\PROGRA~1\\MYPROG~1\\MYDATA~1.TXT");
    File mFileB = new File("C:\\Program Files\\My Program\\My Data File.txt");
    DataInputStream mInputA = new DataInputStream(new BufferedInputStream(new FileInputStream(mFileA)));
    DataInputStream mInputB = new DataInputStream(new BufferedInputStream(new FileInputStream(mFileB)));
    System.out.println("Contents of file A:");
    while (mInputA.available() > 0) {
      System.out.println(mInputA.readLine());
    System.out.println("\nContents of file B:");
    while (mInputB.available() > 0) {
      System.out.println(mInputB.readLine());
    System.out.println("\nAre file A and file B the same file?");
    System.out.println(mFileA.equals(mFileB) ? "Yes" : "No");
}Running this gives the following output:
Contents of file A:
First line of the file.
Second line of the file.
Third and final line of the file.
Contents of file B:
First line of the file.
Second line of the file.
Third and final line of the file.
Are file A and file B the same file?
NoIt seems that the different representation of the paths (short 8.3 file names, vs. long file names) is confusing Java into believing that they are two separate files, even though the example above confirms that they are in fact the same file by showing the contents from input streams derived by the two File objects (which are, needless to say, identical).
So, does anyone know how to reliably determine whether two File objects point to the same file?
Cheers,
Martin

How to compare two date Objects

Hi,
I have two Calendar Objects, one is coming from client and one is my server time, I need to evaluate that incoming time with server time so that if it is sent before an hour back then i should not do anything on that request Object. I have converted the incoming String into Calendar Object and how can i evaluate these two Calendar Objects including their hours and minutes.
Thanks in advance

bajjurireddy, ignore Mobiquity's post. It contains no useful information and will only serve to confuse and frustrate you.

Images XOR, AND, etc... logical operators to compare two distinct objects

is there a way of comper two images without comparing all it bytes...
the problem: actually I�m parsing the values of the bytes of the two images and then comparing it...
idea: if I have the two byte arrays containing the image info.. may I use a logical operator to compare these objects ??

FelipeGaucho again,
Did you come up with an optimized method for logical operators? I actually want to perform the boolean operations to turn most pixels of an image to zero, then compress that (as in your post 'String compressor II'). Are these two posts related for you as well? They are separated by several months.
abnormal,
I'm assuming that Java's classes would be optimized, but if my code will execute at the same speed as theirs, then I guess I can stop searching for optimized (or already provided) classes. Do you know if Java's provided classes run faster than classes we create? I'm going to test the provided System.arraycopy against my own while waiting for a reply.

Comapring two Calender Objects for same Date object

hi,
I am having problem with Comparing two Calender Objects which is having same Date value but time stamp is not same.when i printed as Calender.getTime()---->i found them as.
Cal1----->Wed Feb 28 20:26:29 IST 2007
Cal2------>Wed Feb 28 00:00:00 IST 2007
Now the method:
While(Cal1.getTime().compareTo(Cal2.getTime()) ==0 ) is Evaluating false.
i dont want to be concerned with time stamp.i want condition to be true.
Please help me .thx in advance.
Cheers
Akash

My comment was directed at the fact that you gave the same answer I did, only faster. There is no other way I am aware of that will be any quicker. Of course, that is looking at a small piece of code out of context, so there may well be a better way.

Compare two mail message

I am writing an application to download mail messages from some other pop3/imap mail servers to the folder that created at default imap server.
I want to compare the message get from server and current messages inside the folder, so I don't get the duplicates. How do I compare two Message object?
Thanks in advance!

The way I will do it is to creat a new class that extends java.mail.Message. In such a subclass, one can override "equal" method to compare the data within.

Comparing two Objects

Hi, I want to compare two objects
using the formula below
if((Integer)v.elementAt(i) == new Integer(comp.getCard(j).getValue())){but it doesn't work
I am trying to compare an element in a vector which was of a type Integer
key1 = new Integer(dk.getCard(f).getValue());note that key1 is actually a key used for a mapping
can anyone tell me how I can compare the elements in vector and the other object was an int.

A: Comparing two Objects

Hello zainuluk,
You can not use '==' operator to compare to objects in Java, 'cause it just compare the reference of two oprands. You should use the "equals()" method, just like this:
if(Integer)v.elementAt(i).equals(new Integer(comp.getCard(j).getValue())){...}
Or you can get the int value of element in the vector to compare using '==' operator:
if(Integer)v.elementAt(i).intValue() == comp.getCard(j).getValue()){..}

How to compare two Objects !!!!

Hi All,
I know that this question has been asked 100 times till now. But trust me I have checked all of them but couldn`t find answer. Here is my question:
I have an objecs. In that object I am setting (Id,Name,DOJ). Now I want to check whether the object I am trying to save in database already exists or not. If exists then I need to check whether all the setters are same for the two objects. Now can anyone tell me ,how to compare two objects directly without comparing the setters individually.
Thanks in advance.

pavan13 wrote:
That is pretty good idea. However I have a query. Does that code actually compare all the setters in a two beans. I don`t want to check each setter seperately.Well, it's pretty meaningless to talk about "comparing setters", setters are methods, they don't have values to compare. Because equals is inside the class, you can simply compare the fields that get set by the setters. "Properties" is probably a better name.
In principal you could write something that tried to find all relevant fields and compare them, using reflection or bean info stuff. The resulting code would be about 50 times longer and take about 50 times longer to run. It's hardly asking a lot to put three comparisons between && operators.
Remember, though, not to compare string fields with ==, you should call .equals on the string fields.
p.s. don't let the bean terminology confuse you. Beans are just ordinary objects which follow a few rules. Personally I wish the term had never been coined.

Hi,
You can use this report to compare two itemizations. The report compares the characteristics item number, item category, cost element, resource, material, cost center, plant/work center, cost center/activity type, operation number, BOM item, assembly indicator, and cost component.
You can access this report as follows:
Accounting ® Controlling ® Product Cost Controlling ® Product Cost Planning ® Material Costing ® Cost Estimate with Quantity Structure or Cost Estimate Without Quantity Structure ® Compare
or
Accounting ® Controlling ® Product Cost Controlling ® Product Cost Planning ® Information System ® Object Comparisons ® For Material ® Itemization Comparison.

Can findText find two different objects at once?

I have written a script that finds all italicized words, then compares them to a character style that italicizes characters. If there are any italicized words that do not use the character style, the user is alerted.
Of course, not all fonts use a fontStyle that equals "Italic." Some use a fontStyle called "Oblique."
I was trying to figure out how the findText function could find two fontStyles at the same time. My solution was to realize that each find is an array. So I made two finds and the concatenated the arrays. The resultant array (here called myFoundItems) elements can be searched through to find any that do not have the correct character style applied.
My question is if the findText function can find more than two different objects at once or are we stuck with concatenating arrays?
Below is part of the script:
var myDoc = app.activeDocument;
initFindReplace(); [This function zeros out anything left in the find/change preferences]
app.findTextPreferences.fontStyle = "Italic";
var myFoundItems1 = myDoc.findText();
initFindReplace();
app.findTextPreferences.fontStyle = "Oblique";
var myFoundItems2 = myDoc.findText();
initFindReplace();
var myFoundItems = myFoundItems1.concat(myFoundItems2);
Thanks,
Tom

Tom,
The reason why you end up with an array of arrays is this: you define an array allMyFoundItems, then you iteratively collect other arrays using findText and insert ("push") these arrays into allMyFoundItems. Instead, you should use concatenate:
var allMyFoundItems = new Array;
for (. . .
   var myFoundItems = myDoc.findText();
   allMyFoundItems = allMyFoundItems.concat (myFoundItems)
If you'll allow me a further comment, you could formulate your test to check whether a fontstyle name contains oblique or italic in one line:
>if (arrFontStyles[k].search (/(italic|oblique)/i) > -1)
And as the script searches but doesn't change anything, there's no need to set the ChangeTextPreferences. Your script could then be stated as follows:
var myDoc = app.activeDocument;
var arrFontStyles = myDoc.fonts.everyItem().fontStyleName;
aa = findFontStyle (arrFontStyles);
function findFontStyle (arrFontStyles)
   var allMyFoundItems = new Array;
   var myFoundItems2 = new Array;
   app.findTextPreferences = NothingEnum.NOTHING;
   for(var k = 0; k < arrFontStyles.length; k++)
      if (arrFontStyles[k].search (/(italic|oblique)/i) > -1)
         app.findTextPreferences.fontStyle = arrFontStyles[k];
         var myFoundItems = myDoc.findText();
         allMyFoundItems = allMyFoundItems.concat (myFoundItems);
         }//end if
      }//end for k
   return allMyFoundItems;
   }//end findFontStyle function
As to formatting scripts in the forum, you can do this by wrapping your code in <pre> and </pre>. Also replace < with < (< causes all lines of code to be displayed on one line). You should also replace curly quotes with straight codes, and tabs with (non-breaking) spaces. I use the following script for that:
tf = app.documents.add().textFrames.add ({geometricBounds: [0,0,'700pt','500pt']})
tf.insertionPoints[0].select();
app.activeDocument.textPreferences.typographersQuotes = false;
app.paste();
app.findGrepPreferences = app.changeGrepPreferences = null;
sara (tf, '&', '&');
sara (tf, '<', '<');
sara (tf, '\\t', '   ');
sara (tf, "'", "'");
sara (tf, '"', '"');
tf.parentStory.insertionPoints[0].contents = '<pre>';
tf.parentStory.insertionPoints[-1].contents = '</pre>';
function sara (tf, f, r)
   app.findGrepPreferences.findWhat = f;
   app.changeGrepPreferences.changeTo = r;
   tf.parentStory.changeGrep ()
Copy the text of the script you want to prepare for posting, then run this above script. It creates a new InDesign document, pastes your script into it, and makes all the necessary changes. Then copy that and paste it into the forum.

Compare two schemas in oracle 11g

Hi All,
Can any one please help me how to compare two schemas in oracle 11g.
Thanks
Edited by: 793914 on Oct 22, 2010 9:33 AM

You can do it with gridcontrol. Look for dictionary comparisons and dictionary baselines.
If you don't have gridcontrol, you can also use SQLDeveloper (free download on otn).
There are two ways to do it with SQLDeveloper.
1) Use Tools->Database Diff. However, you need a change management license to use this functionality. I've never used this.
The free way is to...
2) Use Tools->Database Export. Run it once for each schema and make sure the "Show Schema" option is NOT checked before exporting the schema. Also make sure you don't export data. You can choose which types of objects to export as well.
Once you have the two export files for the two schemas then simply run a diff tool on your platform. Use the diff command line for linux or winDiff or something similar in windows.
