Scanner in = new Scanner(System.in);
double arr[] = new double[20];
int l = arr.length;
double p = 1.0;
System.out.println("Enter 20 numbers:");
for (int i = 0; i < l; i++)
{
arr[i] = in.nextDouble();
}
for (int i = 0; i < l; i++)
{
p *= arr[i];
}
System.out.println("Product = " + p);
System.out.println("Square of array elements :");
for (int i = 0; i < l; i++)
{
double sq = Math.pow(arr[i], 2);
System.out.println(sq + " ");
}
}
