Hello,
I'm wondering if it's possible to get sound which other apps are playing for example from music or movie player. If it is then how to do this?
Edit: I've probably found a solution, but didn't check if it works. VAC - Virtual Audio Cable. It installs virtual sound card in system so we can play all of our sounds into it and then retrive it through Java Sound API with TargetDataLine. It's platform dependent, but it's always an option. There is also StereoMix available in some sound cards and I think it's worth of notice. On linux it's probably possible to achieve it with JACK.

Hey,
I have an quick question about the keyword new.
Basically I'm not sure what the new word does and would like to know why exaclty why you use it.
The best way I learn is by seeing examples so can someone reply with an example where if new was not present a piece of code would not work
Mucho gracias

Basically, the keyword new is to initialize a new object. If you need to create an object, you would use the new keyword to initialize the object such as, Car myCar = new Car(). This creates a new Car object which is then assigned the variable name myCar. Here is a link to java's tutorial page to find some more examples and more information about the keyword new.

To expand on this example and tie in the idea of an "instance" of an object:
CCarClass *myCar = new CCarClass();
CCarClass *sisterCar = new CCarClass();
This would create two specific and individual instances of the class, each its own object, on the heap (as opposed to the stack). They will persist until you delete them (which in C++ you must do yourself to clean up resources).
delete myCar;
delete sisterCar;

In java of course you do not delete them.
They are cleaned by the garbage collector when there are no more active references to them.

lol... didn't realize this was posted in the java forum... my bad! assumed C++
|
|
|
|

Just to add to that , the new keyword basically allocated memory location for the object to be stored. if we simply create a object variable we are simple creating a handle to access that memory location and when we use new we alocate memory
so in the above example myCar is the handle to memory location assigned by new Car();
|
|
|
|
|
When used in an expression it results in the following
1. Creation of a instance of a class
2. Initialization of that class instance into a known state.
3. Returns a reference to that instance.
There might be other results as well but the above is probably sufficient.

hi
I have CCNA certificate .
I want get name of all interfaces in one cisco router(AS 5300) with use SNMP protocol in java.
may give me any reference or source code for this purpose .
please help me.

I think it is likely that you will get more information from the technical manuals (or support site) of the Cisco router. This is not really a Java question.

Only if you need it to get a job.

Difficult to say definitively. Some employers place a lot of weight on having certification, some think it adds no value at all.
I think that if you are planning to work as a contractor or "coder for hire" then this is worth having as it can show a commitment to your professional skills development and a certain basic level of competence. If you are looking for a long-term permanent job then its value is more questionable. In those cases, people will probably be more interested in your actual experience and how relevant it is to the role they are seeking to fill.

It add some additional and valuable weight in your Profile as well as in your CV. infact It would also gives a brand value to your resume which will help you in getting good pay and job.

You will probably want to use JDBC[^] which does most of the hard work for you.

System.out.println("success load driver");
}catch(ClassNotFoundException cnfe){
System.out.println("not use Driver "+cnfe);

Hi,
I've an assignment to make a program that should generate all the permutations of a string one by one. I know many algorithm of generating permutations using recursion, but question has asked to generate it one by one. So deliverable should contain a class called "PermutationIterator" which should have a method "hasNextPermutation" and "nextPermutation". They have given one hint, make a "tailIterator" object of type "PermutationIterator" inside a "PermutationIterator" class (like a node of LinkedList) and then do some funny things with it. I can't figure out where should I start....any help would be appreciated.
Note: You can't generate all permutations at one time, then store it into an array and then call each of them one by one. Please don not suggest this way.
Thank you
Shivam Kalra

hi..
check the following code..
<script type="text/javascript">
var indMoney = function (v)
{
v = (Math.round((v - 0) * 100)) / 100;
v = (v == Math.floor(v)) ? v + ".00" : ((v * 10 == Math.floor(v * 10)) ? v + "0" : v);
v = String(v);
var ps = v.split('.'),
whole = ps[0],
sub = ps[1] ? '.' + ps[1] : '.00',
r = /(\d+)(\d{3})/;
while (r.test(whole))
{
whole = whole.replace(r, '$1' + ',' + '$2');
}
v = whole + sub;
return v;
}
</script>
The result of the above function is displaying like this 123,123,123.00
but i want in this format 12,31,23,123.00 i.e indian currency format..
