Not All the Classes and Interfaces Are Listed Here

Hi Ranchers,

In SCWCD, there would be around 5 to 7 questions testing the API skills irrespective of the topics. Here I have summarized all the inputs in a single document in the most memorable manner. This would help you to familiarize before giving an exam but I am pretty sure that one needs to acquire more information of these API. Please look at the way it is organized.

It is not complete UML for APIs, but still the most basics are covered.

The one highlighted in blue color are more expected one than the normal. But it does not mean that the normal can be left out.

Not all the classes and interfaces are listed here.

It carries most important one from both Servlets and Jsps. Tag class hierarchies are also added.

 Source:

I have not missed any questions from this; I hope everyone will also do so.
