In java. Please explains with comments.

a. Write a program to reads numbers (double) from a file. The data type is double. Keep track of how many numbers you read in and place the numbers into an array. Assume that there are no more than 100 numbers to read in. In all the methods that follow, the parameter int n represents the number of records read in step a (which may be less than 100) b. Write a method with the header double compute Avg int n, double1 array) that computes and returns the average of the numbers in the array c. Write a method with the header void compareToAvg (int n, double avg, double array) to compare each number in the array to the average and, in the method ,print each number in the array and the text above average, below average, equal the average next to the number as appropriate. d. Write a method void smallest(int n, double 1 array) that will print the smallest number and the position (from 0) in the array e. Write a method void largest(int n, double array) that will print the largest number and the position (from 0) in the array f. In main do the following i. ii, iii. iv. Call the method computeAvg and store the returned value in a variable named avg. Then print the value of avg. Next call the method compareToAyg Then call the method smallest Then call the method largest
