1. In java , How collection is single unit of objects ? Presented By Infocampus

5. What is Collection in java? Collection represents a single unit of objects i.e. a group. What is framework in java? - provides readymade architecture. - represents set of classes and interface.

6. Collection consist of the following ---

7. -Interfaces: These are abstract data types that represent collections. Interfaces allow collections to be manipulated independently of the details of their representation. In object-oriented languages, interfaces generally form a hierarchy. Java course in bangalore

8. - Implementations: These are the concrete implementations of the collection interfaces. In essence, they are reusable data structures. Infocampus Software Training institute

9. - Algorithms: These are the methods that perform useful computations, such as searching and sorting, on objects that implement collection interfaces. The algorithms are said to be polymorphic: that is, the same method can be used on many different implementations of the appropriate collection interface.

10. Benefits of the Java Collections Framework ---

11. Reduces programming effort: By providing useful data structures and algorithms, the Collections Framework frees us to concentrate advanced java training in bangaloreon the important parts of your program rather than on the low-level "plumbing" required to make it work.

12. Increases program speed and quality: This Collections Framework provides high-performance, high-quality implementations of useful data structures and algorithms.

13. Fosters software reuse: New data structures that conform to the standard collection interfaces are by nature reusable. Java/j2ee classes bangalore The same goes for new algorithms that operate on objects that implement these interfaces.

14. Allows interoperability among unrelated APIs: The collection interfaces are the vernacular by which APIs pass collections back and forth.

15. Reduces effort to learn and to use new APIs: Many APIs naturally take collections on input and furnish them as output. There was little consistency among these ad hoc collections sub-APIs,

17. -> A collection is an object that can hold references to other objects. The collection interfaces declare the operations that can be performed on each type of collection. -> The classes and interfaces of the collections framework are in package java.util.
