An Interface is like a template similar to abstract class
with a difference where it uses only abstract methods.

In simple words, an interface is like a class using
interface keyword and contains only function
declarations(function with no body).

An Interface should be implemented in the class and all the
methods or functions should be overwridden in this class.

for eg:

interface InterfaceName{
function fun1();
function fun2(a,b);
}

class ClassName implements InterfaceName{
fuction fun1(){
function implementation.......
}
fuction fun2(a,b){
function implementation.......
}
}
