Hi,

I have a query regarding instanceof operator that is being used it used to check that whether the object passes is the instance of that class or not,, but I also see that it was also used with interface but interface can't be instantiated then how we can use instance of with interface..?please guide me with a short example..!!

any class that implements an interface IS in essence an instanceof the interface.
it can be confusing. for example you can say
SomeInterface theInterface = new SomeClassThatImplements();
theInterface.someMethod();
how does the interface now have a method that does something?

Think of the instanceof as an operator who will tell you if the object you provided is of a specific type.
Consider the hierarchy


As you can see both Canines and Felines are Animal types So of you say something like
myCanine instanceof Animal it will evaluate to true

The details should be in the Java Language Specification, but it isn’t easy to read.
