Difference between awt ang Swing Interview Question n other Question

hi every one i use to think that i know java atlest so much that i can crack a lolcal comp interview but ........................
i ansered few Question but was speachlees when was asked few of this i do not remember all of them
1] difference between awt and swing.
2]System.out.println();
System is a class out is a variable so who come a variable calling a method.
3]are constractor inherateed in java.

1] difference between awt and swing.AWT is based on an abstraction of platform-specific, heavy-weight components. Swing is written entirely in java.
>
2]System.out.println();
System is a class out is a variable so who come a
variable calling a method.Do you mean how come?
In that case, the answer is simple: Because out is a variable, it can be redirected/compared against, etc much easier
3]are constractor inherateed in java.Kind of a trick question, as the answer is yes and no. Constructors are not inherited, but every constructor in the subclass must call one and exactly one constructor of the superclass

Differences between awt and swing

Ive written the following code, however Ive implemented the gui in awt rather then swing. Ive been told it hs too be in swing. What is the difference between swing and awt what will I need to change in my program so that its done using swing rather then the awt? Heres the code:

Difference between AWT,Swing and swt

Hello,
I am giving a seminar about swing in which I need to point out differences between AWT,Swing and SWT(Software Widget Tool).
I have two questions:
1)I read that-A heavyweight component is one that is associated with its own native screen resource (commonly known as a peer). A lightweight component is one that "borrows" the screen resource of an ancestor-which makes it lighter.Can anybody explain What native screen resource is and how it is borrowed?
2)I read that SWT uses native widgets and how can it be better than swing?If it is in what way?

Use Swing for new projects. AWT is the rendering layer underneath Swing in many cases, and AWT provides utility things like Graphics. SWT is an alternative to Swing which used more native rendering, but actually with Java 6, Swing is using a lot of native rendering.
Fire up NetBeans and use Matisse. Build an application. Run it under Windows, and then under Linux, and then realize how great it is.

What are the differences between Turn in Final Timesheet and the other option: Send Progress for Selected Tasks?

Hello,
The resource filled his/her timesheet in PWA.
Now :
What are the differences between Turn in Final Timesheet
and the other option: Send Progress for Selected Tasks?
Thanks

You are partially correct and partially wrong.
Turn
in Final Timesheet sends
the timesheet to the Timesheet Manager for Approval
but task update always goes to Status manger of the task. Taks manager you can see in MPP(insert status manager field then check)
Yes
after approval progress will be available in MPP as well as in Projectweb app as % complete .
Send
Progress for Selected Tasks
Send progress of selected task to status manager after approval update will be available in both MPP and Projectweb
app as % complete.
In Send
Progress for Selected Tasks Timesheet
Manager doesn't receive anything in his Approval center
because all the update directly go to Status manager Approval center.
Here you have to understand
that there are two role Timesheet Manager(for timesheet approval) and Status manager(for task
actual approval)

Is there a difference between the Ethernet WAN port and the other 3 Ethernet Ports on a Time Capsule?

As posted previously, my time capsule will not set up properly because I get an IP address conflict pop up window. Is there a difference between the "Ethernet WAN Port" and the other three ports on the back of the Time Capsule? I may have the DSL modem hooked into the "Ethernet WAN Port". Thanks.

it depends what you want to achieve and what configuration you have on your DSL modem/router.

The advantages and disadvantages of both applets and Swing are the small fluffy elephants you get inside of every box. They're quite well trained and can skeletonize your neighbors' annoying pets upon command.

Sync Performance difference between AWT & JSP MI application

Hello,
I would like to know, if there are any performance differences, when I sync from AWT Smart Sync MI application compared to JSP Smart Sync Mi Application?
Thanks & regards,
Purnima

Hi Purnima,
the sync logic for the MI AWT client and the JSP client is identical, so the performance is expected to be equal.
During the sync the "sand clock" page is displayed. This is done in the corresponding UI technology and here a slight differnce of resource consumption is there between AWT and JSP (JSP --> Browser rendering, periodic pull;). The resources consumed by this user interaction (processor time, memory) can not be used for inbound data processing etc. and therefore a slight difference in synchronization performance could come up. Though I do not expect recognizable differences (from an end user perspective...) due to this.

Difference between the design of clusters PCLx and others like RFBLG etc .

There are a few nagging questions which I was not able to find in the forum hence i have to post a new question.
I am a little confused about the difference between the different clusters .
If i start with RFBLG i.e. the cluster for BSEG BSEC etc ,I can see that the tables which are part of this cluster
can be viewed through different methods like
1) whr usd list for RFBLG
2) dd02l table and give the required parameters there
now when I compare this with another so-called cluster PCL1 if find that PCL1 is not recognized as a cluster
and also I am not able to see the same in dd02l table when i give PCL1 and the tabtype as cluster which I was able to see
for the RFBLG ,there are other tables similar to RFBLG .
1) SO what is the difference between the RFBLG type of clusters and the PCLx type of cluster
2) are pclx and rfblg..type of clusters same ?
3) why does PCL1 shows that it is a transparent table ? where as rfblg shows in a diff way in se11
4) i know we access data from PCL1 using import and export stmts ,DO OR CAN WE DO THE SAME FOR RFBLG
5) I found that each and evry cluster table had diff fields ,this was kinda surprising for me as I had been thinking
that all cluster tables need to follow a certain rule ,SO WHO DECIDES THE FIELDS OF A TABLE CLUSTER ?
6) PCL1 has the index button enabled ,which again I think is not according to the cluster table rules?how?
7) I understand that we can save data in form of internal tables in the PCL1 cluster ,can we do the same in RFBLG ?
8) Can I think on lines that PCL1 and RFBLG type of cluster are two totally different types of data dictionary objects
and the usage and implementation of both of them is different and that the design and the BASE of both of such objects
is different .
I know this is a long list but I am sure that answers to these questions would really require some one who has really really work hard and invested a lot of time in understanding the dictionary system.I am awaiting a few answers ,few hints and a healthy discussion till we get them .
Thanks ...

Hello,
1/
BSEG is a typical Cluster Table.
This means that the physical table BSEG does NOT exist in the database, physical data for BSEG is stored in the database (table) cluster RFBLG.
In ABAP however you can perform selects on BSEG (with all fields from the SAP repository structure, see SE11 on BSEG), during execution the SAP database layer will translate these statements to physical selects in the RFBLG database table, so in ABAP this is transparant.
More info :

PCL1, PCL2, ... are normal SAP transparent tables, however in HR they are often called HR cluster table.
Transparent tables are SAP objects where there is also a database table with the same name that contains the physical data.
However the PCL tables are somewhat different from normal transparent tables (data is compressed, external programs can not interpret the data, ...).
This means that in ABAP you can not use simple SQL statements to access data in PCL tables (because of compressed format).
In stead statements like EXPORT TO DATABASE and IMPORT FROM DATABASE need to be used.

What difference between Jtextfield of Swing and Textfield of awt.

Differences between old JavaFX and the new one: some questions

Hi,
I'm coming back to my JavaFX studies after 2/3 months and I see that some things are different.. Now, I have some questions:
1) I see that javafx.ui was deprecated or rewritten in favor of javafx.ext.swing. Why there are a javafx.application.Frame and a javafx.ext.swing.SwingFrame? Which one should I use?
2) Neither javafx.application.Frame or SwingFrame has the "*undecorated*" attribute that javafx.ui.Frame has. I got this feature only reimplementing createWindow() function like this:
function createWindow(): java.awt.Window {
       //this is a trick, because Frame don't has a undecorated attribute.
       var f: java.awt.Window = super.createWindow();
       (f as javax.swing.JFrame).setUndecorated(true);
       return f;
}Should I report this as a bug/RFE in [http://bugreport.sun.com/bugreport/] ? Where should I report bugs and RFEs to JavaFX?
3) Why frame's opacity don't work in Linux? Is this a Linux restriction or only a "not yet implemented" feature?
My java -version:
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b15, mixed mode)
4) Where is that cool feature that permits me to easily animate in JavaFX doing only x = [1..100] dur 1000? Now, I need to use this more advanced (and more complicated) Timeline object.
Timeline {
        keyFrames:Timeline [
                KeyFrame{time : 0s values: x => 0.0},
                KeyFrame{time : 2s values: x =< 180.0 tween Interpolator.LINEAR}
        ]//keyFrames
}//Timeline;Sorry for the amount of questions.
TIA,
Bruno E. Grossi

The new ones will be substantially faster than yours because it has 8-cores instead of four, a faster Frontside Bus, and faster RAM speed.
You could use the same RAM, but since the new ones can accommodate a faster RAM module you would cause the machine to run slower by using the slower RAM from your old machine.
You can use the same hard drives since both machines support SATA drives.
On the other hand you could just be happy with what you have! It's probably more than you need.

What the difference between AirPort Extreme from $99 from the other that cost $199,$299or $399

I want to but a airpor extreme but what the difference from the AirPort Extreme starting $99 to the other ones that cost $199,$299 or $399

At $99 you have the Airport Express, $199 the Airport Extreme, $299 a 2TB Time Capsule, and $399 a 3TB Time capsule. The Airport Express has 100Mb/sec ports and no AC wireless. The Extreme is gigabit and does AC wireless. The Time capsule are essentially an Extreme with a built in hard drive for Time Machine backup or general Network Attached Storage.

Is there a size difference between iPod Touch 1G home button and other versions of iPod Touch?

I have an old iPod Touch 1G home button that got stuck. So I bought a new home button to replace it and I'm having trouble fitting it in the hole that I'm replacing. I'm not sure the new button I have is for iPod Touch 1G or for other iTouch versions.
Does anyone know where I find a video how to replace iPod Touch home button and where can buy the home button if the button I have is not for 1G?

this is a shop online were you can buy the home button http://www.repairsuniverse.com/ipod-touch-1g-button-replacements.html
and this is a video telling you how to replace it http://www.youtube.com/watch?v=izf0HLSwL7w

About the difference between the AWT components and the swing components

As we know that an AWT component has a peer, but dose a lightweight component(e.g: a swing component) has also a peer? And could somebody tell me that who and how creates the CLICKED_EVENT when I click a JButton(a swing component), and where the CLICKED_EVENT to go util it was processed by a method like btn_ok_clicked(Event e)? And if I click a Button(an AWT component), what's the difference?
Thanks a lot!

The main difference is that AWT are native components, and Swing components are entirely in java written. That's besides the look and feel. There are a lot of other differences between AWT and Swing, and there are better described in the documentation.
