Use the following java file to begin your NumStatsArray class.

NumStatsArray.java

public class NumStatsArray{
//Create a private array as a double as final
________________________________________

    public NumStatsArray(double[] a){
        arr = a;
    }

  
  /* Iterate through and cancatenate all values except last and follow each with a comma. 
  Create string with a "{" the beginning and end it with a "}". 
 */
 public String toString()
      
      
      
      
      
   //Create a method that returns average fo all values as a double. Be sure to crate a sum variable as a double.   


      
  /* Create min and max variables set to first value in array. Then, iterate all values and update max every time new 
  largest value found. Finally, update min every time new smallest value found and return min - max.  

*/

      
      
      

  
// Create booleans for ascending/descending sequence as true. 
  
  
        /* Iterates through all except the first value in the array, and checks if
         * current value is smaller than the previous (meaning arr is not decreasing
         * or is greater than the previous (meaning arr is not increasing).
         */
        for(int i = 1; i < arr.length; i++)
        {
            if(arr[i] < arr[i-1])
            {
                increasing = false;
