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
