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 :
- Stream : A sequence of elements supporting sequential and parallel aggregate operations.
- 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.
Example 1 :
// 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);    }} |
Output :
3 4 5 6 7
Example 2 :
// 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();          Stream<Object> stream2 = Stream.concat(stream1,                                    Stream.of("Geeks", "for", "Geeks"));          // Displaying the elements        stream2.forEach(System.out::println);    }} |
Output :
3 4 5 6 7 Geeks for Geeks
