An interface allows you to specify a list of methods that a class must implement. However, a class can implement one or more interfaces, which has helped Java get rid of the impossibility of multiple inheritance. To define an interface, you use the interface keyword as follows: An interface consists of methods that contain no implementation. } Interfaces may inherit from other interfaces using the extends keyword. In the below program Interface “B1” has been used with the class “A1” in order to implement the multiple inheritances. In the below-listed PHP program’s example, there are two interfaces with the names “B1” and “C1” which are actually playing the role of the base classes and there is always a child class with the name “Multiple1” and we are now invoking all the other functions by using the “pavan” object.
