Groovy & Gradle: JVM Automation and Build Engineering · Lesson

Groovy Collections Enhancements

Discover Groovy's powerful additions to Java collections, making data manipulation simpler and more expressive.

Groovy's Collection Power-Up

Groovy supercharges Java's standard collections (List, Map, Set) with many new, convenient methods. This makes your code shorter, more readable, and much more expressive.

You'll spend less time writing boilerplate and more time solving problems!

Easy List Initialization

Creating and populating lists in Groovy is a breeze. No need for new ArrayList<>() or repetitive add() calls. Just use square brackets []!

class Main {
  static void main(String[] args) {
    def numbers = [1, 2, 3, 4, 5]
    def names = ["Alice", "Bob", "Charlie"]
    println "Numbers: " + numbers
    println "Names: " + names
  }
}
