LongStream sorted() returns a stream consisting of the elements of this stream in sorted order. It is a stateful intermediate operation i.e, it may incorporate state from previously seen elements when processing new elements. Stateful intermediate operations may need to process the entire input before producing a result. For example, one cannot produce any results from sorting a stream until one has seen all elements of the stream.
Syntax :
LongStream sorted() Where, LongStream is a sequence of primitive long-valued elements. This is the long primitive specialization of Stream.
Exception : If the elements of this stream are not Comparable, a java.lang.ClassCastException may be thrown when the terminal operation is executed.
Return Value : LongStream sorted() method returns the new stream.
Example 1 : Using LongStream sorted() to sort the numbers in given LongStream.
// Java code to sort LongStream // using LongStream.sorted() import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream
LongStream stream = LongStream.of(10L, 9L, 8L, 7L, 6L);
// displaying the stream with sorted elements
// using LongStream.sorted() function
stream.sorted().forEach(System.out::println);
}

Example 2 : Using LongStream sorted() to sort the random numbers generated by LongStream generator().
// Java code to sort LongStream // using LongStream.sorted() import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream by generating
// random elements using LongStream.generate()
LongStream stream = LongStream.generate(()
-> ( long )(Math.random() * 10000 ))
.limit( 5 );
// displaying the stream with sorted elements
// using LongStream.sorted() function
stream.sorted().forEach(System.out::println);
}
