Transforming the elements of a stream

Some of the most useful intermediate operations you can use with streams are those that allow you to transform the elements of the stream. These operations receive elements of a class and return the elements of a different class. You can even change the type of stream and generate an IntStream, LongStream, or DoubleStream from Stream.

In this recipe, you will learn how to use the transforming intermediate operations provided by the Stream class to convert its elements into a different class.

Getting ready

The example of this recipe has been implemented using the Eclipse IDE. If you use Eclipse or other IDE such as NetBeans, open it and create a new Java project.

How to do it...

Follow these steps to implement the example:

1. First, we'll implement some auxiliary classes we will use in the example. First, implement the Person class, which stores the basic attributes of a person, and the PersonGenerator class, which generates a List of random Person objects. Please...
