We need a voice recorder which can run at client. What we are trying to achieve is, user can record his voice, can play it and then save it on server.
We have searched many things about this .Now we are getting a url from js "blob:http://localhost:8080/4ad0a470-cdfa-4b7b-a094-a6eed2e5fdda".
we are using "http://subinsb.com/html5-record-mic-voice".
So now how we can handle this url in java to save a file on server.

Thanks

Can any body tell me how much object has been created implicitly or explicitly?
Here is any way (method or anything) to find out created object?

public class stringClass {

public static void main(String args[]){
String name="Hemant";
String sName=name+"Khandal";
String s=sName+"Java";
String ss=new String("Hemant");
}

}

Now I am talking only above code.I want to call overridden method foof() from main().Is it possible ? If yes then please let me know how can we do this?
It's pleasure for me if you add some line as per situation.
This is only for understanding java concepts.
Thanks in advance.
