IntStream sorted() in Java
Last Updated :
06 Dec, 2018
IntStream 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 :
IntStream sorted()
Where, IntStream is a sequence of primitive int-valued
elements. This is the int 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 : IntStream sorted() method returns the new stream.
Example 1 : Using IntStream sorted() to sort the numbers in given IntStream.
import java.util.*;
import java.util.stream.IntStream;
class GFG {
public static void main(String[] args)
{
IntStream stream = IntStream.of( 10 , 9 , 8 , 7 , 6 );
stream.sorted().forEach(System.out::println);
}
}

Example 2 : Using IntStream sorted() to sort the random numbers generated by IntStream generator().
import java.util.*;
import java.util.stream.IntStream;
class GFG {
public static void main(String[] args)
{
IntStream stream = IntStream.generate(()
-> ( int )(Math.random() * 10000 ))
.limit( 5 );
stream.sorted().forEach(System.out::println);
}
}
