I am developing an application in which I have to integrate facebook. But, whenever, I give reference of facebook SDK in my application, it does not take it. The process aborts at 73%. I downloaded SDK from github and I had also installed EGit eclipse plug-in. But still, I am unable to provide reference. I am not getting what is the actual problem. Whether is there any problem in eclipse or some other problem is there?

The new capacity is the larger of:

- The minimumCapacity argument.
- Twice the old capacity, plus 2.


If that's the behaviour whenever the capacity is increased, it would explain what you saw.



Thank you sir, I got the clarity

Better yet include the code you are using....if you can.



It has nothing to do anything with the constructor. Any way I am using StringBuffer().

Hi, I have a doubt regarding string buffer. The default size of string buffer is 16. If we go on adding the elements, then on exceeding the size, the capacity will get doubled. It should be 32. But the capacity() returns 34. How the size gets increased?

Let's turn this around -- why don't you explain why it should?



Sir, I got my answer, it was done to keep the language clean as assigning multiple meanings to single operator will lead to more programming errors. Why I got this doubt because people say that it doesn't support operator overloading, while actually it does. For instance, + is used in string concatenation as well as arithmetic operations and this in-built feature of java.

Sorry, my question is wrong. I mean to ask why it does not support user defined operator overloading.

Hi, I am planning to learn EJB. Is it required to learn ejb2 prior to ejb3.

I mean to ask that generally a method is invoked on an object and getServletContext() is in servletconfig interface. So, how container locates the servletconfig object.

For eg:
We write as follows



Similarly, here also it should be as . So how the container locates the servletconfig object?

Instance Variable =Defined at Instace/Object Level.

Static Variables are initialized ,loaded with Class itself.

But instance variable initialized when Object for that Class is instantiated.

In other words - For 1 class ,its different objects can have different values for same instance variable.(Each instance =can have its own value)
But for same class ,static variable (since belongs to class itself ) -same value is shared by each object.




Thank you Lucky Sir, Actually this was my doubt which I wanted to clear.
