Day 5, Java Holiday Calendar 2016, CRUD Operations

5. CRUD Operations


Today’s tip is an introduction on how to use open-source Speedment to expand the Java 8 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 done 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
