In this article, we will learn the Collectors.toCollection() method in Java, an essential tool for collecting elements into a specific type of collection, such as a List, Set, or any other collection type. Java 8 introduced a new, powerful feature called Streams, which enables functional-style programming to process sequences of elements. One of the key utilities in the Streams API is the Collectors class. What is the Collectors.toCollection() Method? The Collectors.toCollection() method is a static method in the Collectors class that allows you to collect elements from a stream into a custom collection. public static Collector toCollection(Supplier collectionFactory) Here ...
