If elements of another collection are present in the collection or not.

Before the Collections Framework, it was hard for programmers to write algorithms that worked for different kinds of collections. Java came with some Collection classes, like Vector , Stack , Hashtable , and Array , but they had their disadvantages. In JDK 1. This course explores all collection types available in the Java Collections Framework, like lists, linked lists, sets, and hashmaps. Collections in Java. The Java Collections Framework is a unified architecture for representing and manipulating collections.

It contains interfaces, their implementation classes, and algorithms to process the data stored in a collection. The Collection interface is extended by other interfaces like List, Set, and Queue. Interfaces : These interfaces supply the abstract data type to represent the collection. The java. Collection is the root interface of the framework. The iterable interface is the root of the whole collection framework. It allows the iterator to iterate through all of the collections.

All classes and interfaces use this interface. The collection interface extends the iterable interface and is executed by the classes in the collection framework. The list interface inhibits a list type data structure where we can store ordered collections of objects.

All framework interfaces are in the java. Implementation classes : The framework provides implementation classes for collections. You can use them to create different types of collections in your Java programs.

Some of the main collection classes include:. Algorithms : These algorithms perform important functions on collections, like sorting lists. ArrayList is the most commonly used implementation of the List interface. Some of its features include:. An ArrayList stores data in a resizable array. When you create an ArrayList, you create an array of size zero. When the first element is inserted, the array size changes to ten. I don't see any 'inversion of control' Ask Question.

Those terms aren't nearly so well-defined, and there isn't a strong distinction as to which the collections in Java are. I'm not saying you, or they, are wrong, I'd just like to see the information in context.

These algorithms are said to be polymorphic : the same method can be used on many different implementations of the appropriate collection interface. In essence, algorithms are reusable functionality. Historically, collections frameworks have been quite complex, which gave them a reputation for having a steep learning curve. We believe that the Java Collections Framework breaks with this tradition, as you will learn for yourself in this chapter.
