Question

create a new Java application called "MinMax" (without the quotation marks) that declares an array of doubles of length 5, and uses methods to populate the array with user input from the command line and to print out the max (highest) and min (lowest) values in the array.

Answer 1

Program Screenshots:

MinMax.java //create Application called MinMax public class MinMax //main method public static void main (String[] args) //create an array of type double //length is 5 double] inputarraynew double [5]; //call the method to pupulate array populateArray (args,inputarray); //call the method to find min and maximum in the array findMaxMin(inputarray) //implement method to get the values //from the command line arguments private static void populateArray (String[] args, double[] inputarray) system. out. printin ("Input Array is:"); //Get the 5 arguments from command line //and store in the inputarray for (int i-0;i<args.length;i++) //convert string to double inputarray[i] Double.parseDouble (args [i]); //print the input arguments System.out.print (args [i]+"

//Implement method to find minimum and maximum array public static void findMaxMin (double[] arr) //declare variables double max, min; //set the starting value as min and max max = min = arr [0]; //use for-loop to compare and compute the //min and max values in the array for (int i-l; i < arr.length; i++) if (arr[i] max) max = arr [1]; if (arrfi] < min) min = arr [i] ; //print the minimum and maximum value system.out.println ("\n\nHighest element in the given array is: "+ max) System.out.println ("Lowest element in the given array is: "+ min);
