LongStream boxed() returns a Stream consisting of the elements of this stream, each boxed to a Long.
Note : LongStream 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<Long> boxed()
Parameters :
- Stream : A sequence of elements supporting sequential and parallel aggregate operations.
- Long : The Long class wraps a value of the primitive type long in an object. An object of type Long contains a single field whose type is long.
Return Value : The function returns a Stream boxed to a Long.
Example 1 :
// Java code for LongStream boxed() import java.util.*; import java.util.stream.Stream; import java.util.stream.LongStream; class GFG { // Driver code public static void main(String[] args) { // Creating an LongStream LongStream stream = LongStream.range(3L, 8L); // Creating a Stream of Longs // Using LongStream boxed() to return // a Stream consisting of the elements // of this stream, each boxed to a Long. Stream<Long> stream1 = stream.boxed(); // Displaying the elements stream1.forEach(System.out::println); } } |
Output :
3 4 5 6 7
Example 2 :
// Java code for LongStream boxed() import java.util.*; import java.util.stream.Stream; import java.util.stream.LongStream; class GFG { // Driver code public static void main(String[] args) { // Creating an LongStream LongStream stream = LongStream.range(3L, 8L); // Creating a Stream of Longs // Using LongStream boxed() to return // a Stream consisting of the elements // of this stream, each boxed to a Long. Stream<Long> 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
