Generate Random Numbers Within a Given Range and Store in a List in Java

To generate random numbers in a given range, the Java code is as follows −

Example

 Live Demo

import java.util.Random;
import java.util.*;
public class Demo{
   public static void main(String args[]){
      Random my_rand = new Random();
      List my_list_1 = new ArrayList();
      int v_1 = my_rand.nextInt(1000);
      int v_2 = my_rand.nextInt(967);
      int v_3 = my_rand.nextInt(1050);
      int v_4 = my_rand.nextInt(10000);
      int v_5 = my_rand.nextInt(100);
      my_list_1.add(v_1);
      my_list_1.add(v_2);
      my_list_1.add(v_3);
      my_list_1.add(v_4);
      my_list_1.add(v_5);
      System.out.println("The random values in the list are : ");
      for(int i=0; i<my_list_1.size(); i++)
      System.out.print(my_list_1.get(i)+" ");
   }
}

Output

The random values in the list are :
677 230 763 1695 48

A class named Demo contains the main function. Here, a new random instance is created along with a new array list. Random elements are created and assigned to variables. These random variables are added to the list using the ‘add’ function. These elements are displayed on the console.
