Collection framework in java tutorial pdf

The Java collection framework provides the developers to access prepackaged data structures as well as algorithms to manipulate data. Next, let us move to the Java collections framework hierarchy and see where these interfaces and classes resides. Get Certified With Industry Level Projects & Fast Track Your Career. filexlib. The Java collections framework provides various data structures and algorithms that can be used directly. This has two main advantages: We do not have to write code to implement these data structures and algorithms manually. Our code will be much more efficient as the collections framework is highly optimized. The Java collections framework gives the programmer access to prepackaged data structures as well as to algorithms for manipulating them. 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.

You'll learn about the core elements — interfaces, implementations, aggregate operations, and algorithms — that comprise the Java Collections Framework. The Java Collections Tutorial
Any group of individual objects which are represented as a single unit is known as the collection of the objects. In Java, a separate framework named the "Collection Framework" has been defined in JDK 1.2 which holds all the collection classes and interface in it.
