Get the name of the Pair class via an instance

By having an instance (an object) of Pair, we can find out the name of its class by calling the getClass() method, as well as Class.getName(), getSimpleName(), and getCanonicalName(), as shown in the following example:

Class<?> clazz = pair.getClass();// modern.challenge.PairSystem.out.println("Name: " + clazz.getName());// PairSystem.out.println("Simple name: " + clazz.getSimpleName());// modern.challenge.PairSystem.out.println("Canonical name: " + clazz.getCanonicalName());

An anonymous class doesn't have simple and canonical names.

Notice that getSimpleName() returns the unqualified class name. Alternatively, we can obtain the class as follows:

Class<Pair> clazz = Pair.class;Class<?> clazz ...
