Today’s tip is an introduction on how to use open-source Speedment to expand Java 8's Streams to support Creating, Reading, Updating and Deleting database entities.

Head out to Speedment's GitHub page to see how to modify your project's POM file. Once you've made the changes, you can connect to an existing database and generate Java code automatically from the database's meta information (like columns and tables). Once completed, your Java Streams becomes much more feature-full, and you can:

Do This

hares.stream()
  .filter(Hare.NAME.equal("Harry"))
  .map(Hare.COLOR.setTo("Brown"))
  .forEach(hares.updater()); 

  // Sets the color to "Brown" for all hares named "Harry" in the DB
