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.

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.

How to add two objects on scene and how to rotate them?

I am beginer on 3d. I am trying do write applet where are 3x3x3 rubic.
My plans are to have 27 litle cubes. There are 6 flats (9 cubes in a flat) so i have six objects groups. My problem at this moment is that i cant find out how to make two objets. Each of this two objects consists from couple more litle objects. Some of litle objects can be in first and second big object. For example it can be two flats of rubic (corner).

Hi all!
I'm reading an xls and i need to fill me oracle objects with java code:
OBJECT_NAME OBJECT_TYPE
LETTURA_OBJ TYPE

In the past weeks i've been using both java code into oracle and oracle objects, but new i need to write those objects with data i read with java, anybody can help me?
I know that the easiest work around would be to put the data i read from the excel file into a table and then fill the oracle objects, but now i want to learn how to write directly those objects with a command like the following one:
a sample of the code i'm tryng to write:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED REPORT."Manage_Excel_ASMBS" AS

How to communicate two PC's with the serial port with Netbeans

Do you know how to do it?
Do you know how to communicate with the parallel port too?
Could you give some ideas?
What commands or instructions I have to use?

What does NetBeans have to do with it?
All these "people" today that start out in Java using all these "nifty" IDE's. All it does is produce exactly this. They think their IDE is Java. Once they no longer have their one specific IDE in front of them, they can no longer function. They have no idea what the classpath, what the compiler actually does, how to package a jarfile, hell, most of the time, they don't even know how to execute a simple application.
As far as your question. Did you even try to Google for some Serial port API package? Assuming you did, did you download it and read the documentation that comes with it? Did you search for a few examples on the web? Did you read them? Did you try them? I can almost guarantee that the answer to everyone of those questions is "no". So, my question for you is, "Why should we help you?" You obviously have no desire to help yourself, so I think we should reciprocate in kind. Don't you?

How to return custJava Object from Java Stored Function/Procedure to Java Application

I WILL PAY $100 FOR SOLUTION.
Oracle JDBC documentation gives step by step on how to return Oracle Type Object to Java Application. No question here.
But is it possible to create Java Stored Function [getMyClass() ] which returns CUSTOM Java based object [MyClass] to Java application like:
//java stored function
class Foo
public static MyClass getMyClass()
return new MyClass();
//java class I want to return to Java
class MyClass
public String getGreetings(String name)
return "Hello " + name;
I tried to do it using intermittent Oracle
Type Object and OracleConnection map to make binding between Java->Oracle->Java. I could
not get throgh meaningless run time ORA Errors. Any kind of help would be greatly
appreciated. If you know the answer please
post it or e-mail [email protected]
null

You don't say which version of the database you are on. There's an interesting looking article on OTN on handling CLOBs in JDBC in 10g. It may well be useful for earlier versions too (but no guarantees).

How to blur two objects in one scene in CS4

I'm going a bit crazy over this. I tried coping the video track, into track 5 and put a matte track in track 6. I got this to work once, but when I view it again, the two blurred out objects are no longer blurred.
I had followed this:
http://www.wrigleyvideo.com/videotutorial/tutdes_ppro2_smoothface.htm
But cracked up the blur a ton more.
Is there another way to blur out two objects in a video? I need something that will STAY. Thanks!

The way effects are stacked is also important.
First Fast Blur then Track Matte.

How to get stylesheet object from JAVA RESOURCE stored in DB

Hi,
I stored a xslt file in the database and have a JAVA RESOURCE file now. How can i get a stylesheet object from this resource file?
I took the following class to get an impression how to get the contents of the resource but -although the name of the resource was spelled correctly- i got a file not found exception.
Whats wrong?
public class PrintRessource {
public static void print (String p_ressource){
try {
Class c = PrintRessource.class;
System.out.println(c.toString());
InputStream file = c.getResourceAsStream(p_ressource);
if (file == null)
throw new FileNotFoundException("XSLT file not in DB");
byte[] buffer = new byte[4096];
int bytes_read;
while ((bytes_read = file.read(buffer)) != -1)
System.out.println(new String(buffer, 0 , buffer.length));
catch (Exception exp) {
System.out.println(exp);
Thanks

The code works as is. I just forgot to add the slash in front of the Resource file name.

How to connect two object selectors.

Hi,
I try to use an object selector as selection for an following object selector in CAF CORE.
What I want:
I choose an employee from the first object selector and click on a button "Show all flights". Now the second selector opens and all flights of these employee are shown.
Is there a tutorial for questions like this? Or could anybody answer my question?
Thanks and best regards
Martin

It's really two diffirent things.
But you can use ObjectEditor pattern with relationship tab which can display flights for certain employee. So, you select some employee from object selector then configured object editor is opened and you go to Relation tab of this object editor and see all the flights.

How to swap two numbers in java

i have an idea in c but i don't know in java..somenoe like to share their idea i appreciate a lot...
here is a sample code in c...hope u can help me in java.....thanks a lot ....
#include<stdio.h>
void swap(int x, int y)
int temp;
temp=x;
x=y;
y=temp;
void main(void)
    int x=10,y=20;
      clrscr();
printf("Before swap:x=%d,y-%d", x,y);
    swap(x,y);
printf("\n After swap:x=%d,y=%d",x,y);
   getch();
#include<stdio.h>
void swap(int* x, int* y)
int temp;
temp=*x;
*x=*y;
*y=temp;
void main(void)
int x=10,y=20;
clrscr();
printf("Before swap:x=%d,y-%d", x,y);
swap(&x,&y);
printf("\n After swap:x=%d,y=%d",x,y);
getch();
}My aim of this program is to make one java file and 2 class files in java and display the output . The first output would be the number before swapping and the number after swapping.....

There are several ways to achieve the results. You can use an array or a custom "Swaper" class to swap two values. Here is an example using generics for better code reuse.
public class Swapper<T> {
   private T first;
   private T second;
   public Swapper(T first, T second) {
      this.first = first;
      this.second = second;
   public void swap() {
      T temp = first;
      first = second;
      second = temp;
   public <T> Swapper<T> swap(T first, T second) {
      return new Swapper<T>(second, first);
   public T getFirst() {return first;}
   public T getSecond() {return second;}
   private static void swap(int[] num) {
      if (num.length != 2) {
         throw new IllegalArgumentException("num array must be of length 2");
      int temp = num[0];
      num[0] = num[1];
      num[1] = temp;
   public static void main(String[] args) {
      // method 1: use array
      int[] num = {1, 2};
      System.out.printf("Before swap:first=%d,second=%d\n", num[0], num[1]);
      Swapper.swap(num);
      System.out.printf("After swap:first=%d,second=%d\n", num[0], num[1]);
      // method 2: use a custom "Swapper" class
      Swapper<Integer> swapper = new Swapper<Integer>(3, 4);
      System.out.printf("Before swap:first=%d,second=%d\n", swapper.getFirst(), swapper.getSecond());
      swapper.swap();
      System.out.printf("After swap:first=%d,second=%d\n", swapper.getFirst(), swapper.getSecond());
      // method 2: using another data type
      Swapper<String> stringSwapper = new Swapper<String>("C#", "Java");
      System.out.printf("Before swap:first=%s,second=%s\n", stringSwapper.getFirst(), stringSwapper.getSecond());
      stringSwapper.swap();
      System.out.printf("After swap:first=%s,second=%s\n", stringSwapper.getFirst(), stringSwapper.getSecond());
      /*    --- OUTPUT ---
       * Before swap:first=1,second=2
       * After swap:first=2,second=1
       * Before swap:first=3,second=4
       * After swap:first=4,second=3
       * Before swap:first=C#,second=Java
