LongStream mapToObj() method in Java
The LongStream mapToObj() method is used in Java to return an object-valued Stream consisting of the results of applying the given function to the elements of this stream.
The syntax is as follows:
<U> Stream<U>mapToObj(LongFunction<? extends U> mapper)
Here, Stream is a sequence of elements. The LongFunction represents a function that accepts a longvalued argument and produces a result. Parameter mapper is a stateless function to apply to each element. The <U> represents the element type of the new stream.</p>
To use the LongStream class in Java, import the following package:
import java.util.stream.LongStream;
The following is an example to implement LongStream mapToObj():
Example
import java.util.stream.Stream;
import java.util.stream.LongStream;
public class Demo {
public static void main(String[] args) {
LongStream longStream = LongStream.range(10L, 15L);
System.out.println("Binary Representation...");
Stream<String> s = longStream.mapToObj(a→ Long.toBinaryString(a));
s.forEach(System.out::println);
}
}output
Binary Representation... 1010 1011 1100 1101 1110
