Interface is a terminology which is used in java to remove the problem which occured in C++ while using multiple inheritance.Interface is of abstract data type which consist of virtual methods and variable(needed to be static and final only).
While in inheritance provides the facility of reusability.Properties of one can be used in another class with the help of inheritance.
Interface is used in java while inheritance is used in C++ and java both.
I know what is Implementation inheritance but i don’t know what’s interface inheritance.Can anyone explain it with example?
Also i was reading a book , and it said that:
In case where you want to use implementation inheritance then it is usually provided by an abstract base class
In the Java programming language, an interface is a reference type, similar to a class, that can contain only constants, method signatures, default methods, static methods, and nested types. Method bodies exist only for default methods and static methods. Interfaces cannot be instantiated—they can only be implemented by classes or extended by other interfaces. Extension is discussed later in this lesson.
but the inheritance is A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class).
Excepting Object, which has no superclass, every class has one and only one direct superclass (single inheritance). In the absence of any other explicit superclass, every class is implicitly a subclass of Object.
Classes can be derived from classes that are derived from classes that are derived from classes, and so on, and ultimately derived from the topmost class, Object. Such a class is said to be descended from all the classes in the inheritance chain stretching back to Object.
Inheritance can be defined as the process where one object acquires the properties of another. With the use of inheritance the information is made manageable in a hierarchical order.
When we talk about inheritance, the most commonly used keyword would be extends and implements. These words would determine whether one object IS-A type of another. By using these keywords we can make one object acquire the properties of another object.
interface are implicitly abstract and cannot have implementations
variables declared in a Java interface is by default final.
Java interface should be implemented using keyword “implements”

Interface is used for achieving goal of multiple inheritance.
Inheritance means taking the properties of base class by child class.
