Functional Programming in Java with Lambda

java-tv.com — Mon, 13 Jan 2020 15:34:10 +0000

Functional programming is a programming style that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a declarative programming paradigm in that programming is done with expressions or declarations instead of statements. For years, the conventional wisdom around attempting pure functional programming in …

Streams in Java 8

java-tv.com — Wed, 09 Nov 2016 18:00:29 +0000

Since Java 8 the JDK has a Stream API. Among numerous other operations the Stream API offers two operations – reduce() and collect() – which are occasionally misunderstood and thus used incorrectly – at the expense of introducing subtle bugs in conjunction with parallel streams. This tutorial discusses the background …
