Java Program Lab #2. Chapter 7. PC #11. Array Operations (Page 491) Write a program that accepts a file name from command line, then initializes an array with test data using that text file as an input. The file should contain floating point numbers (use double data type). The program should also have the following methods: * getTotal. This method should accept a one-dimensional array as its argument and return the total of the values in the array. * getAverage. This method should accept a one-dimensional array as its argument and return the average of the values in the array. * getHighest. This method should accept a one-dimensional array as its argument and return the highest value in the array. * getLowest. This method should accept a one-dimensional array as its argument and return the lowest value in the array. double_input1.txt double_input2.txt PLEASE MODIFY THIS CODE, SO WHEN I UPLOAD IT TO HYPERGRADE IT PASSES ALL THE TEST CASES, BECAUSE WHEN I UPLOAD IT TO HYPERGRADE IT DOES NOT PASS THE TEST CASES. IT HAS TO PASS ALL THE TEST CASES.
