In this tutorial you’ll see how to convert a Stream to list using collector method and utility methods like toList() and toCollection() of Collectors class in Java Stream API. 1. A simple example to collect Stream elements into an ArrayList. import java.util.List; import java.util.stream.Collectors; import java.util.stream.Stream; public class StreamToList {…
In this tutorial we’ll see what options are there to get the last element of the stream using the Java Stream API. 1. Using reduce() method reduce method in the Java Stream API is used to perform a reduction on the elements of the stream so that the stream is…
When using Java streams, most of the time you will have a Collection as a source for the stream but you can also do the opposite i.e. obtain a Collection from a Stream. To do that you can use collect() method in the Java Stream API. Here note that collect()…
In this tutorial you’ll see how to sort stream of objects on multiple fields. Sort stream of objects on multiple fields To sort a stream of objects on multiple fields you need to use two methods- 1. Stream<T> sorted(Comparator<? super T> comparator)– sorts the elements of this stream according to…
In this tutorial we’ll see how to use Java Stream sorted() method with the help of few examples. Table of contents Syntax of sorted() method in Java Stream API Sort List of integers in natural order Sort List of integers in reverse order Sort List of Strings Sorting List of…
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…
Java Stream API provides two methods max() and min() where- max()– Returns the maximum element of this stream according to the provided Comparator. min()– Returns the minimum element of this stream according to the provided Comparator. Table of contents Java Stream max() method max() method Java examples Java Stream min()…
In the Java Stream API there are two methods findFirst() and findAny() where- findFirst() returns the first element of the Stream. findAny() returns any element of the Stream. Table of contents Java Stream findFirst() method Java Stream findFirst() examples Java Stream findAny() method Java Stream findAny() examples Java Stream findFirst()…
In the Java Stream API tutorial we have gone through the intermediate and terminal operations, in this tutorial we’ll go through Java Stream filter() method in detail. Java Stream filter method filter() is an intermediate operation which returns a stream consisting of the elements of this stream that match the…
limit(long maxSize) method in the Java Stream API truncates the stream so that it is no longer than maxSize in length and returns the new stream with limited elements. limit method in Java Stream Syntax of the method is as given below. Stream<T> limit(long maxSize) Here maxSize is the limit…
