What is collectors in Java?

Collectors in Java are part of the Java Stream API, introduced in Java 8, and are used to accumulate elements of a stream into a collection, such as a List, Set, or Map. They provide a flexible way to transform and collect data from streams.

Collectors offer various predefined implementations, such as toList(), toSet(), and toMap(), among others. They enable the processing of stream elements with operations like grouping, partitioning, and reducing. This makes data manipulation more intuitive and concise.
