Hi Friend,

Try the following code:

import java.util.*;
class  ArrayExample2{
    public static void main(String[] args){
            Random random = new Random();
            int arr[]=new int[10];
            System.out.println("Array of Random Numbers are: ");
            for (int i = 0; i < arr.length; i++) {
            arr[i] = random.nextInt(50);
            System.out.println(arr[i]);
            }
            System.out.println("Elements at even index:");
            for (int i = 0; i < arr.length; i++) {
            if(i%2==0){
             System.out.println(arr[i]+" at :"+i);
            }
            }
            System.out.println("Elements which are even:");
            for (int i = 0; i < arr.length; i++) {
            if(arr[i]%2==0){
            System.out.println(arr[i]);
            }
            }
            System.out.println("On reversing, Array changes to: ");
            for(int i=arr.length-1;i>=0;i--){
                System.out.println(arr[i]);
            }
            System.out.println("First Element is: "+arr[0]+" and Last ELement is: "+arr[arr.length-1]);

    }
}

Thanks
