class A { JPanel myJPanel = new MyJPanel(); ... JPanel getPanel() { return myJPanel } } class MyJPanel extends JPanel { ... } class B { ... JPanel rootPanel = new JPanel(); // rootPanel.add(new MyJPanel()) //<---- Line 1 // rootPanel.add(new A().getPanel())//<--- Line 2 }

Line 1 works but Line 2 does not. (when using one or the other...)
Any suggestions why ?

Whats the general technique to login to a website from within a java progam?

Has anyone recently have had the experience of having their H1B transferred recently AND having the visa stamped on their passport, from Canada?
Is there a long wait time to get an appointment at the Canadian US Embassy ?
Is there a good FAQ list site, for Canadian/Mexico H1B transfer visa stamping?

Thanks

You are right. I was thinking about implementation specific issues, such as if one were to pass a List of states that changed, then the Observer would have to parse the list and figure out what changed etc...a little more expensive than I had thought initially...

Thanks

The interface java.util.Observer has a method
void update(Observable o, Object arg)

This is called when a state change occurs in the Observable.
I came across this
Sun Tutorial, but am still unclear as to how do you pass the entire state information using just one Object variable.

Has anyone come across a similar situation...?

Thanks

Was looking to replace my aging presario laptop, and was looking closely at the new MacBook. Has anyone in this forum, made the switch from a PC to a Mac, recently...

I'm trying to use the class java.io.SequenceInputStream to read from a collection of java.io.InputStreams.

Assuming I have two seperate InputStreams wrapping two seperate files that look something like -

File A:
Line 1 : Apple
Line 2 : Oranges<EOF>

File B:
Line 1 : Pears
Line 2 : Grapes<EOF>

When I try to concatenate these two streams and read them using java.io.SequenceInputStream, Line 1: Pears is never read.(Assuming the concatenation ordering is File A, File B) But if I change File A to this -
File A:
Line 1 : Apple
Line 2 : Oranges
<EOF>

(there is a <CR> after Oranges this time), then it works fine. Is this something to do with how <EOF>s are encoded in Windows?

Pressing "Enter" while editing a .java file in eclipse, causes the cursor to jump to the same indentation level as the previous line. How do I disable this ?

How is Retrospect for backing up data? Are there any good opensource ones available ?

Does anyone have some feedback on the Roomba vaccum ? Trying to find out if it really does the job well...

Is there a convention for naming methods to set a property of a GUI component viz. enabled/disable or visible,not visible ?
Like say for a JButton called button1...the method would be button1SetEnabled(boolean value) or setEnabledbutton1(boolean value) or something else ? I'm guessing there must be a standard for naming these methods...

Lets say I have an XML file of the format
. . . <Root> <nSamples> 25 </nSamples> <Item name = "A"> <nSamples>2</nSamples> . . . </Item> </Root>

If I parse the above with a SAXParser and override DefaultHandlers startElement and endElement methods, how do I differentiate between the 2 'nSamples' tokens from each other. What would be an alternate parsing technique that would give me the nested level info of each tag?

Is anyone aware of an Open Source library for 2D/3D plotting of data in Java. (Something like The Colt Distribution for technical computing in java.)

With so many preferences in the Eclipse Editor, I am not sure if this is the intended behaviour - When I click on one of the methods or fields, in the outline view, I see ONLY that method/field and nothing else in the editor window. If I do a Find for instance, its scope is limited to that method/field I've selected in the outline view. I know it was not doing this earlier. Where do I go to remove this option/preference ?

Is there a way I can iterate through the contents of a directory without having to use listFiles ?

I am trying to avoid having to store the file names in memory, if there is going to be just way too many files...
