Quizplus · Accepted Answer

The notation < E extends Comparable< E > > is used to declare a generic type that implements the Comparable interface. Here, E can be replaced with any other identifier that represents the type of object being compared. The Comparable interface is used to define the natural ordering of objects, so this notation ensures that the generic type being declared has a natural ordering based on its own type. This notation is commonly used in Java code to define classes such as ArrayList and TreeSet.
