How are you creating this application? Java does not automatically show anything as a default when a Swing application starts up, so my guess is you must be using some toolkit or framework to do this?

This is quite a controversial topic, and is the subject of much debate in the Java community. If you search on Google for something like "javafx versus swing" you will find lots and lots of opinions.

To answer your specific questions:

JavaFX uses a different syntax from Swing, and has its own language, JavaFX Script, which is not Java. However, you can use JavaFX with Java.

There are three main advantages to using JavaFX, as I understand it. First, JavaFX has better support for animations and media such as video and audio. Second, JavaFX has a similar idea to WPF in as much as it separates the visual design from the code, the idea being that the application can be built by a specialist programmer, and the look and feel can be put together by a specialist graphic designer. (The technical implementation is different from WPF, though.) Third, JavaFX offers better support for mobile platforms than Swing does.

Disadvantages: mainly that JavaFX isn't fully ready yet. It is still lacking some basic components you might need for writing desktop applications, such as a table component. It is still evolving and just this week Oracle announced that JavaFX Script will not be supported in the next version of JavaFX.

If you want to develop a desktop application, you don't have to use JavaFX but you can if you want to, if it suits your requirements. Personally, I wouldn't use it because Swing gives me everything I need for the kind of applications I build, but if I had a requirement that Swing couldn't meet, I might consider JavaFX. For example, if someone wanted me to write something with JavaME I would look at maybe using JavaFX, or at least weigh it up against LWUIT (another toolkit for Java GUIs on mobile phones).

Hi,

I have a store which has different sort of stuff like table,chair, rug etc. I define a class for public characteristics like name, color, size etc. id addition public features, if each item has particular characteristic do I have to implement inheritance? for example each item come up with different price in different month?

thanks for your help,in advance.

yes, you could (and should) take advantage of inheritance in such a situation: put the data members and code methods that are common to all kinds into a common base class, then "specialize" the things you need by creating new classes that inherit from said base class.

Most text books have an Animal,Cat&Dog example (or something similar) illustrating the concept.

in C# we have a DataObjectFieldAttribute(True, True, True); is there any command like this in Java?

Please help.

Too many qustion marks.
But as I'm in a good mood:

If all you want is a folder then
New -> Other...
Catagory: Other
Fiel Type: Folder

If you want to add a folder for a package, just add class and enter the package name, netbeans will sort out the structure foir you.

I am doing my B.E project and i need help. My project is Advance Visual Components for JAVA using language java. In this project, we are developing 3rd party components using netbeans or any other java developer tool. This components helps in rapid development of application or java. For example, a component in which all the validation of the mobile number will be present. The developer just have to Drag and Drop this component in the developer kit while programming. Like this, we are going to develop more components. I hope you have understood my project.
And the main thing is this components must be integrated with any java developer kit such as netbeans.
Thanks and i look forward to positive help from you.

I'm positive that there is a question in there somewhere, but I cannot see it.

Interesting. Looking at the source comments I can see that you have ported code that needs to be implemented in C# to become code that needs to be implemented in Java.

J2SE is Jave v2 Standard Edition. This is the 'base' Java environment.

Servlets are part of J2EE - Jave v2 Enterprise Edition - and, simply put, are small components used in building large scale systems. Here[^]'s a taster of how Servlets work.

hi..
Java Servlet Programming is something and J2SE is something.
Both are different.
J2SE is Java 2 standard addition.
and Servlet Programming is rise of server-side Java applications.and Servlet run on server side

Servlets are supported through the Servlet API, an extension to the Java programming language.

Hello guys,

I have been working on dynamic construction of object by using reflection (Java 6 SE platform). I have noticed for example that there is a method:

Class.getConstructor(Calss<?>[])

You pass the argument Class objects to this method and it gives you the corresponding constructor back. This works fine in most cases. But it has one problem. It dos not support autoboxing.
For example if the constructor of my class takes an int parameter and and i ask the Class object for this class for the constructor like this: Class.getConstrucort(new Class[]{Integer.class}) i will get the NoSuchMethodException indicating that there is no matching constructor. If i match the constructor argument in the class definition exactly to the parameter type given to the getCosntructor() method then i will have no problem.

Did anyone had any similar problems?
If any one has a solution or a workaround for this, i would need an advice.

Cheers
