An interface defines a set of methods that all implementing classes must support. The interface itself is the contract that you define for the implementing classes. Actually, an interface is a contract, when an object is an instance of a class - they are different things that don't have too much in common.

Likewise, wHAT IS interface and example?
Interfaces in Java. Like a class, an interface can have methods and variables, but the methods declared in an interface are by default abstract (only method signature, no body). A Java library example is, Comparator Interface. If a class implements this interface, then it can be used to sort a collection.
Similarly, what is an interface agreement? An interface agreement is a document that defines an interface between two teams / locations / functional responsibilities. It may typically include (or refer to) battery limit drawings, interface matrix, or interface register, for example. It may be signed by both parties when agreement is reached, but not always.
Secondly, what do you mean by interface?
In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these.
What is the purpose of interface in OOP?
Interfaces in Object Oriented Programming Languages. An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class). For example, say we have a car class and a scooter class and a truck class. Each of these three classes should have a start_engine() action.
Related Question AnswersHow do you declare an interface?
An interface is declared by using the interface keyword. It provides total abstraction; means all the methods in an interface are declared with the empty body, and all the fields are public, static and final by default. A class that implements an interface must implement all the methods declared in the interface.WHAT IS interface and its types?

3 Answers. The intuitive answer is that regardless of what interface you refer to, the object implementing the interface must be a subclass of Object . i.e. all interfaces are assumed to contain method signatures corresponding to methods in the Object class.When would you use an interface?
Use abstract class when you want to extend a comman base and where you want to provide a default implementation to the abstract method. Use interface when you want to exactly implement all the abstract methods to the class implementaing the interface and no default body to a method can be provided.How do interfaces work?
An interface contains definitions for a group of related functionalities that a non-abstract class or a struct must implement. An interface may define static methods, which must have an implementation. An interface may provide a default implementation for any or all of its declared instance members.WHAT IS interface and its use?
