In this post, we will create an array and populate the array with some random values.<\/p>\n

Declare an array<\/h3>\n

We can declare an array of integers using the syntax:<\/p>\n

int[] array;<\/p>\n

Create an array with random values<\/h3>\n

We can create an array of ten integers using the syntax.<\/p>\n

array = new int[10];<\/p>\n

Java program<\/h3>\n
import java.util.Random;\r\n\r\npublic class RandomArrayDemo {\r\n  public static void main(String[] args) {\r\n    int[] array;\t        \/\/ declare an array\r\n    array = new int[10];\t\/\/ create an array of ten integers\r\n    Random rand =new Random();\r\n    for (int i = 0; i < array.length; i++) {\r\n      array[i] = rand.nextInt(100); \/\/ generate random number\r\n      System.out.print(array[i] + \" \");\r\n    }\r\n  }\r\n}\r\n<\/pre>\n
 <\/p>\n
<\/h3>\n
Sample Output<\/h3>\n
40 26 32 73 5 8 15 16 86 25<\/p>\n
 <\/p>\n
Note that : As expected for each run of the program the values in the array would change.<\/p>\n
