Java Random nextLong() Method

The nextLong() method of Random class returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence.

Syntax

Parameters

Return Value

The nextLong() method returns the next pseudorandom, uniformly distributed long value.

Example 1

import java.util.Random;
public class JavaRandomNextLongExample1{
public static void main(String[] args) {
      Random random = new Random();
//return the next pseudorandom long value
Long val = random.nextLong();
System.out.println("Random Integer value : "+val);
      Long val1 = random.nextLong();
System.out.println("Random Integer value : "+val1);
   }
}

Output:

Random Integer value : 3977537424970713389
Random Integer value : 5733671541347552387

Example 2

import java.util.Random;
public class JavaRandomNextLongExample2 {
public static void main(String[] args) {
      Random random = new Random();
for (double i=0;i<5;i++) {
//return the next pseudorandom Gaussian value
Long val =random.nextLong();
System.out.println(val+" ");
      }
   }
}

Output:

7543819037091046117 
-3342512197386667364 
-4465337898535811745

Example 3

import java.util.Iterator;
import java.util.Random;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.BlockingQueue;
public class JavaRandomNextLongExample3 {
public static void main(String[] args) {
        Employee employee1 = new Employee("Reema     ", "Panda   ", "reemapanda18@gamil.com        ");
        Employee employee2 = new Employee("Geetanjali", "Sharma  ", "geetanjaliSharma28@gamil.com  ");
        Employee employee3 = new Employee("Vineet    ", "Tanjea  ", "VineetTanjea56@gamil.com      ");
        Employee employee4 = new Employee("Himanshu  ", "Bhardwaj", "himanshubhardwaj0604@gamil.com");
int capacity = 100;
BlockingQueue<Employee> queue = new ArrayBlockingQueue<Employee>(capacity);
queue.add(employee1);
queue.add(employee2);
queue.add(employee3);
queue.add(employee4);
        Iterator<Employee> iterator = queue.iterator();
        Random random = new Random();
////Returns an iterator over the elements
while(iterator.hasNext()){
            Long val =random.nextLong();
System.out.print(iterator.next());
System.out.print(val);
System.out.println();
        }
    }
}
class Employee{
private String f_name;
private String l_name;
private String email;

public Employee(String f_name, String l_name, String email) {
this.f_name= f_name;
this.l_name= l_name;
this.email= email;
    }
public String toString(){
return "FirstName-"+f_name+" :  LastName-" +l_name+" : Email-"+email+" : Id-";
    }
}

Output:

FirstName-Reema      :  LastName-Panda    : [email protected]         : Id--6149450654700259232
FirstName-Geetanjali :  LastName-Sharma   : [email protected]   : Id--1351029507738091616
FirstName-Vineet     :  LastName-Tanjea   : [email protected]       : Id--2724724873264125475
FirstName-Himanshu   :  LastName-Bhardwaj : [email protected] : Id--2199305912644374368
