Common SQL clauses and their equivalents in Streams
Functional programming allows for quasi-declarative programming in a general purpose language. By using powerful fluent APIs like Java 8’s Stream API, or jOOλ’s sequential Stream extension Seq or more sophisticated libraries like vavr or functionaljava, we can express data transformation algorithms in an extremely concise way. Compare Mario Fusco’s imperative and functional version of the same alg
Java 8 Friday: No More Need for ORMs
Every Friday, we’re showing you a couple of nice new tutorial-style Java 8 features, which take advantage of lambda expressions, extension methods, and other great stuff. You’ll find the source code on GitHub. Debates about the usefulness of ORM (Object-Relational Mapping) have been going on for the last decade. While many people would agree that Hibernate and JPA solve a lot of problems very well

List<Schema> result = new ArrayList<>(); try (Connection c = getConnection()) { String sql = "select schema_name, is_default " + "from information_schema.schemata " + "order by schema_name"; try (PreparedStatement stmt = c.prepareStatement(sql); ResultSet rs = stmt.executeQuery())
