    By using Visitor design pattern we can add new virtual methods to

    existing classes without modifying their core structure.

    In JDK there are many places where Visitor design pattern is used.

    Some of these are as follows:

    javax.lang.model.element.AnnotationValue and

    AnnotationValueVisitor

    java.nio.file.FileVisitor and SimpleFileVisitor

    javax.lang.model.type.TypeMirror and TypeVisitor

    javax.lang.model.element.Element and ElementVisitor

    javax.faces.component.visit.VisitContext and

    VisitCallbac
