## Generate Array Of Random Numbers In Java

Let’s understand first why we need to code to find the random numbers, because-

Irregular number of generators are valuable for a wide range of purposes. Beside clear applications like producing irregular numbers for the motivations behind betting or making eccentric outcomes in a PC game, randomness is significant for cryptography. Cryptography requires numbers that aggressors or attackers can’t figure.

Simple code to find the array of random numbers is shown below:-

import java.util.*; import java.util.Scanner; class RandomNumbersExample { public static void main(String[] args) { int number; System.out.println("Example to find the array of random numbers"); System.out.println("Enter the range upto where you need to get the random numbers:"); Scanner sc= new Scanner(System.in); number=sc.nextInt(); Random rand = new Random(); System.out.println("*****OUTPUT*****"); System.out.println("Random numbers are:-"); for (number = 1; number <= 10; number++) { System.out.println(rand.nextInt(number)); } } }

The output of the above code is-

Example to find the array of random numbers Enter the range upto where you need to get the random numbers: 100 *****OUTPUT***** Random numbers are:- 35 87 0 85 96 82 10 93 54 4
