IntStream distinct() is a method in java.util.stream.IntStream. This method returns a stream consisting of the distinct elements. This is a stateful intermediate operation i.e, it may incorporate state from previously seen elements when processing new elements.
Syntax :
IntStream distinct()
Where, IntStream is a sequence of
primitive int-valued elements.
Below given are some examples to understand the function in a better way.
Example 1 : Printing distinct elements of Integer stream.
import java.util.*;
import java.util.stream.IntStream;
class GFG {
public static void main(String[] args) {
IntStream stream = IntStream.of( 2 , 3 , 3 , 5 , 6 , 6 , 8 );
stream.distinct().forEach(System.out::println);
}
}
|
Output :
2
3
5
6
8
Example 2 : Counting value of distinct elements in a stream.
import java.util.*;
import java.util.stream.IntStream;
class GFG {
public static void main(String[] args) {
IntStream stream = IntStream.of( 2 , 3 , 3 , 5 , 6 , 6 , 8 );
long total = stream.distinct().count();
System.out.println(total);
}
}
