Yes, generally this is a good practice to use interfaces wherever you can. there are two important exceptions for containers, though: when you must use a hash based container for objects that are not comparable, use hashset<t> or dictionary<tk,tv>, when you declare a local variable, using var for implicit typing is often preferred for. The collection interface (java.util.collection) and map interface (java.util.map) are the two main “root” interfaces of java collection classes. what is a framework? a framework is a set of classes and interfaces which provide a ready made architecture. in order to implement a new feature or a class, there is no need to define a framework. While the collection interface adds no stipulations to the general contract for the object.equals, programmers who implement the collection interface "directly" (in other words, create a class that is a collection but is not a set or a list) must exercise care if they choose to override the object.equals. Collection interface. the collection interface is the interface which is implemented by all the classes in the collection framework. it declares the methods that every collection will have. in other words, we can say that the collection interface builds the foundation on which the collection framework depends. Collection collections; it is an interface. it is a utility class. it is used to represent a group of individual objects as a single unit. it defines several utility methods that are used to operate on collection. the collection is an interface that contains a static method since java8. the interface can also contain abstract and default methods.

Java collection class is used exclusively with static methods that operate on or return collections. it inherits object class. the important points about java collections class are: java collection class supports the polymorphic algorithms that operate on collections. java collection class throws a nullpointerexception if the collections or. The collections framework has a lot of interfaces, setting the fundamental nature of various collection classes. lets study the most important interfaces in the collections framework. the collection interface. it is at the top of collection heirarchy and must be implemented by any class that defines a collection. its general declaration is,.
