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…

Write a Java application for a grade book using arrays: Create an array to store 20 test grades, random numbers between 0-100, inclusive.  Print these 20 grades Calculate and print the average grade Calculate and print the highest and lowest grades Complete BMI arrays template BMI.java   Use two int arrays to store n numbers from user input, called height[] and weight[].  "The BMI is defined as the body mass divided by the square of the body height" Calculate BMIs and store values into a double array called bmi[].    Write a method to print an array, use an enhanced for loop in the print method.  Print the BMIs by invoking the print method.  import java.util.Scanner;public class BMI{public static void main(String[] args){Scanner key = new Scanner (System.in);int num = // use Scanner object to get an integer// declare an int array for heightint[] height = new int[num];// declare an int array for weight below...// declare an array for BMI array...for ( ){ // iterate all array…

Write a C# code that contains a two dimensional integer array which has the size 3x4; • A random number (between 25 and 75) will be assigned to each element of the array. Elements will be shown in matrix format at Console window. • The transpose of the array will be written to the "myFile.txt" file. An example after running the program The content of myFile.txt | myFile - Notepad File Edit Format View Help Console window C.
