IntStream boxed() in Java

IntStream boxed() returns a Stream consisting of the elements of this stream, each boxed to an Integer.

Note : IntStream boxed() is a intermediate operation. These operations are always lazy. Intermediate operations are invoked on a Stream instance and after they finish their processing, they give a Stream instance as output.
Syntax :

Stream<Integer> boxed()

Parameters :



  1. Stream : A sequence of elements supporting sequential and parallel aggregate operations.
  2. Integer : The Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int.

Return Value : The function returns a Stream boxed to an Integer.

// Java code for IntStream boxed()
import java.util.*;
import java.util.stream.Stream;
import java.util.stream.IntStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an IntStream
        IntStream stream = IntStream.range(3, 8);
  
        // Creating a Stream of Integers
        // Using IntStream boxed() to return
        // a Stream consisting of the elements
        // of this stream, each boxed to an Integer.
        Stream<Integer> stream1 = stream.boxed();
  
        // Displaying the elements
        stream1.forEach(System.out::println);
    }
