Finding all classes implementing a Specifc Annotation in a method; Java reflection [duplicate]

This question already has an answer here:

• How to find annotated methods in a given package? 3 answers

How can we find all classes which have methods annotated with Specific annotation using java reflection? For eg: I have various methods say A(), B(), C() annotated with @Annotation present across multiple classes say Class1, Class2, Class3.

How can I find this list containing Class1, Class2, Class3.

Thanks!
