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
