resizable layout swing when disappears JPanel

resizable layout swing when disappears JPanel

pI have many jPanel (panelF) that are added in other jPanel(panelB).
jPanelF contain jPanelC. img src=http://i.stack.imgur.com/U1vts.png
alt=enter image description here/p pI have set the layout to add them as
follows:/p precode PanelB.setLayout(new BoxLayout(this.PanelB,
BoxLayout.PAGE_AXIS)); PanelF panelF1 = new PanelF(); PanelB.add(panelF1);
PanelF panelF2 = new PanelF(); PanelB.add(panelF2); /code/pre pI set
visible false in jPanelC1. But JPanelF2 preserves distance and not want to
make that blank space/p pimg src=http://i.stack.imgur.com/NTSR3.png
alt=enter image description here What I want is that when disappearing
JPanelC1. Distance is maintained between the jPanelF and not be a white
space. I tried validate() and change the layout but I fail. What would be
the way? Thank you very much. Sorry for my English/p pknow if there are
something like $(#panelC1).fadeOut(slow)? would be ideal./p

Inheritance in java, casting subclass to superclass

Inheritance in java, casting subclass to superclass

I am writing a software in java and this inheritance problem always crops
up. Funny enough, I don't get problems when i run the program in my IDE
(Eclipse Kepler) but once i export it to an executable jar, problem
starts. I think am the only one experiencing this problem because all
searches on google show the direct opposite. My problem is I have an
interface named VoteType. This interface is implemented by serveral
concrete classes. I save the concrete implementation to a file using
XMLEncoder and retrieve it using XMLDecoder. But when i try to cast it to
the interface it implements (VoteType), i get a ClassCastException. What
could possibly be causing this? Please help.

Euclid's Algorithm Theory

Euclid's Algorithm Theory

I understand the following code always produces the GCF of two integers. I
can see that variable b passes its value to a, and variable r passes its
value to variable b. This is according to Euclid's algorithm. However, I
don't understand why this works. Namely, how does the remainder share a
common factor with a and b?
// x and y are integers; x >= y > 0
a = x;
b = y;
r = a % b;
while (r > 0}
{
a = b;
b = r;
r = a % b;
}
// b is the greatest common factor of x and y

C# : overridden Equals method not getting called

C# : overridden Equals method not getting called

I have a class named 'x' which overrrides Equals() as follows:
public override bool Equals(object obj)
{
if(obj is x)
{
return ((obj as x).key == this.key);
}
return false;
}
When the following extension method tries to use the above override for
comparison, Equals() doesnt get used:
public static bool Contains(this HashSet<x> set, char key)
{
x SearchKey = new x(key);
return set.Contains(SearchKey);
}
I get the expected behavior only when I modify the first line in the
extensio method as follows:
x SearchKey = new x(key);
Can you please explain this behavior?
I had expected that, Equals() would get called against instance of x
itself since it is a subset of Object. What am I missing?

Input field to only accept a specific number

Input field to only accept a specific number

I have created a form and now I want to add an input field inside it which
would only accept a specific number i.e. the digit '4'. This is more like
a spam check where the user is asked that 'What is the answer of 1+3?' and
then he/she would've to enter the digit '4', in the input field, in order
for the form to get processed. This could also work in a manner that if
any other number is entered inside the input field and the form is
submitted, a pop up window is fired explaining the error.
I have created a jsfiddle which only accepts the digit 4 but sadly it is
allow accepting 'full stops'.
HTML:
<input id="humancheck" type="text" maxlength="1" name="humancheck"
required />
Javascript:
jQuery('#humancheck').keyup(function () {
this.value = this.value.replace(/[^4-4\.]/g,'');
});

If $\lim_{n\to \infty} a_n = A$, $\lim_{n\to \infty} b_n = B$ and $A

If $\lim_{n\to \infty} a_n = A$, $\lim_{n\to \infty} b_n = B$ and $A

If $\lim _{n\to \infty} a_n = A$, $\lim _{n\to \infty} b_n = B$ and $A<B$,
prove $\lim _{n\to \infty}\max\{a_n,b_n\} = B$
Side question: Does the $A<B$ imply $a_n < b_n$?
Since we know $a_n$ converges to $A$, doesn't the problem kind of suggest
$\max{a_n,b_n} = b_n$ (as we also know $A\not = B$, so if the max were
$a_n$ the limit would have to be A, but then the problem is futile)?
