Java.util.collections. public class collections extends object. this class consists exclusively of static methods that operate on or return collections. it contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed by a specified collection, and a few other odds and ends. All general purpose collection implementation classes (which typically implement collection indirectly through one of its subinterfaces) should provide two "standard" constructors: a void (no arguments) constructor, which creates an empty collection, and a constructor with a single argument of type collection, which creates a new collection with the same elements as its argument. in effect, the latter constructor allows the user to copy any collection, producing an equivalent collection of. By facilitating interoperability among unrelated apis, the java collections framework frees you from writing adapter objects or conversion code to connect apis. increases program speed and quality: this collections framework provides high performance, high quality implementations of useful data structures and algorithms. the various implementations of each interface are interchangeable, so programs can be easily tuned by switching collection implementations. Introduction tells you what collections are, and how they'll make your job easier and your programs better. you'll learn about the core elements that comprise the collections framework: interfaces, implementations and algorithms. interfaces describes the core collection interfaces, which are the heart and soul of the java collections framework. you'll learn general guidelines for effective use of these interfaces, including when to use which interface. A collection represents a group of objects, known as its elements. some collections allow duplicate elements and others do not. some are ordered and others unordered. the jdk does not provide any direct implementations of this interface: it provides implementations of more specific subinterfaces like set and list.

The collection object is a set so if the same customer enters multiple orders, there is only one element for that customer in the list of customer ids. if the program tries to add an element that is the same as an element already in the set, the second element is simply not added. The java collections framework is a contract with developers and programs to provide specified behavior. it is essentially impossible to redefine the functionality of jdk classes—that is, to change the contract—in java updates or even major releases. some small refinements to the api contract are possible, but most improvements available to the java collections framework are internal changes. even internal changes must be considered carefully to ensure that they do not have unwanted side. Learn more about streams and collections. lambda expressions are a major new language feature introduced in java se 8. related to that change are the streams api and aggregate operations on collections. the collection interface now exposes methods stream<e> stream () and stream<e> parallelstream (), for obtaining sequential or parallel streams.
