(Java se5,called generics)A parameterized type (compiler-level technology) is a class, the compiler can automatically customize to work with particular Types.Object Creation LifetimeWhen to destroy object?C + + takes the approach that control

Collection:hold single elements, automatically resize, won ' t hold Primitives3. Map:holds associated pairs, automatically resize, won ' t hold Primitives4. Like an array, a List of also associated numerical indexes to Objects--thus,arrays and Lists is ordered containers.5. The behavior of Queues and stacks is provided via the LinkedList6. A Map is a-to-associate not i

(This also applies to private methods, which is automatically final.)Convariant return typesJava SE5 adds convariant return types, which means, a overridden method in a derived class can return a type derived From the type returned by the Base-class methodDesigning with InheritanceIf you choose inheritance First when you ' re using a existing class to make a new class, things can become needlessly comp Licated.A better appro

During the Spring Festival read the next "java:the complete Reference" found this writing in simple, I think a question, the book a lot of content we also know, but why we can not write such a book, so comprehensive, so systematic, so simple and easy to understand. Have to admire Herbert Schildt programming skills, need to mention is Herbert Schildt wrote a lot of Java and C, C + + books, he is the C, C + +, Java
