Well Himanshu I don't know about the new Khalid Mughal book but the one that I had didn't had generics in it. For generics I would recommend generics tutorial from sun. As far as collection goes, I feel that the K&B book is sufficient for collections. You just need to practice to be more familiar with collections. The khalid mughal book is too technical in it's language on the collections chapter...

If you have access to Sierra & Bates HeadFirst Java Book, its a little clearer. Generics in my opinion is about Type Safety, i.e letting the JVM know what Object types are expected in a collection for example, with the compiler complaining if the wrong type is added to the collection.

For example



Hope this throws some light on the matter!


be a well encapsulated person, don't expose your privates, unless you public void getWife()!
