例：

// Java program to demonstrate the example 
// of long nextLong() method of 
// Random

import java.util.*;

public class NextLongOfRandom {
 public static void main(String args[]) {
  // Instantiates Random object
  Random ran = new Random();

  // By using nextLong() method is
  // to return next long pseudo-random
  // value by using Random Value Generator

  long val = ran.nextLong();

  // Display val
  System.out.println("ran.nextLong(): " + val);
 }
}
