modernfeatures.streams.StreamBasicsPrintNamesAlpha
public class StreamBasicsPrintNamesAlpha extends Object
Demonstrates the use of Java 8 Streams and functional interfaces to process a list of names.

This example showcases how to:

  • Create a Stream from a List
  • Use Predicate for filtering names
  • Use Function for mapping/transformation
  • Use Consumer for processing/output
  • Chain intermediate operations (filter, map, sorted)
  • Trigger terminal operation (forEach)
The stream pipeline prints all names longer than 3 characters, in uppercase, sorted in alphabetical order.
