When streams were added to Java 8, I wanted to jump on the bandwagon. I read blog posts, watched videos, attended workshops to understand what this was all about. After a while, I became comfortable enough… but I was unhappy with the implementation: while streams offer methods with a functional approach, legacy collections do not. When one wants to use Java capabilities on an existing collection, the later needs to be transformed to a stream, and then back again. For example, the f
This is the 7th post in the Learning Clojure focus series. Coming from a Java background, I’m currently trying to learn the Clojure programming language, with the help of online resources and mentorship. Some weeks ago, I tried to wire things together by trying to find equivalent methods to those available in Java streams. While I managed to get things working, writing working code and writing idiomatic code are two very different things. I was fortunate to have a good degree of feedback fr
This is the 6th post in the Learning Clojure focus series. In general, one learns by comparing to what one already knows: I’m learning Clojure in that way. Coming from a Java background, I naturally want to use streaming features. So, what would be the Clojure counterparts of Java’s functions filter(), map(), etc.?
