Create an array with random values in a java program

In this post, we will create an array and populate the array with some random values.

Declare an array

We can declare an array of integers using the syntax:

int[] array;

Create an array with random values

We can create an array of ten integers using the syntax.

array = new int[10];

Java program

import java.util.Random;

public class RandomArrayDemo {
  public static void main(String[] args) {
    int[] array;	        // declare an array
    array = new int[10];	// create an array of ten integers
    Random rand =new Random();
    for (int i = 0; i < array.length; i++) {
      array[i] = rand.nextInt(100); // generate random number
      System.out.print(array[i] + " ");
    }
  }
}

 

Sample Output

40 26 32 73 5 8 15 16 86 25

 

Note that : As expected for each run of the program the values in the array would change.
