Java Stream distinct() method is used to get the distinct elements of the stream. It means this method filters out the duplicate elements. Syntax of the distinct method Syntax of the distinct() method in the Java Stream API is as given below- Stream<T> distinct() 1. Method returns a new stream…
In this tutorial we’ll see examples of Collectors.partitioningBy() method which is part of the Collectors class in the Java Stream API. Collectors.partitioningBy() method partitions the input elements according to a passed Predicate (which defines the condition for partitioning), and organizes them into a Map<Boolean, List> with values assigned to two…
In this tutorial we’ll see how to use Collectors.teeing() method which is added in Java 12 to the Collectors class in the Java Stream API. Collectors.teeing() method The teeing() method let you create a composite of two Collectors and there is also a third argument; a merging function. Every element…

In this tutorial we’ll see some examples of Collectors.groupingBy() method in Java Stream API. Collectors.groupingBy() method works similarly to “group by” statement in SQL which groups the elements as per the specified columns. This method also groups the elements according to the passed property and returns grouped result as a…
In this tutorial we’ll see how to use Collectors.joining() method to concatenate the input elements into a String. It is a handy utility method provided by the Collectors class in Java Stream API to quickly convert array elements or elements in a collection to String. There are three overloaded Collectors.joining()…
