Java Random - longs() Method
The java.util.Random.longs() method returns a stream producing the given streamSize number of pseudorandom long values. A pseudorandom long value is generated as if it's the result of calling the method nextLong().
Syntax
public LongStream longs(long streamSize)
Parameters
streamSize |
Specify the number of values to generate. |
Return Value
Returns a stream of pseudorandom long values.
Exception
Throws IllegalArgumentException, if streamSize is less than zero.
Example:
In the example below, the java.util.Random.longs() method is used to get a stream of pseudorandom long values.
import java.util.*;
import java.util.stream.LongStream;
public class MyClass {
public static void main(String[] args) {
//creating a random object
Random rand = new Random();
//generating a stream containing 10
//long random numbers
LongStream stream = rand.longs(10);
//printing all random numbers from the stream
stream.forEach(System.out::println);
}
}
One of the possible outcome is given below:
