Practical Work 04-1: Lambdas

Intro

The goal of this work is to write lambda expressions in order to get familiar with them.

Prerequisites

Warning

Lambdas & streams are a Java 8 feature; you need a JDK >8 installed.

Instructions

Installation of the project

  • The first step is to download the starting project code.zip and to extract it inside your workplace.

  • Then import the project inside your workplace (you may need to create an empty project in Eclipse for that, then import->existing files)

Everything is in the code!

  • By reading the code of the provided project, you'll find the FIXME comments that will guide you to realize this practical work.

Hint

There is a preferred way to go through the methods:

  • begin with getTopTenItems(),
  • go then to filterByGenre() & filterByBorrower(),
  • you can now safely have a look at searchByTitle()
  • proceed with printList(), and maybe have a look at printSortedList() while you're at it
  • you are now ready for !#java CulturalItem.getAverageRating(), as it is a little tedious , but should be easy by now :)

When you want to test your work, just remember that the output of the main() method in your console should not change.
