Asked Nov 13, 2019

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).

Then 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.


Expert Answer

Step 1

Program Algorithm-


Step1: Define the class named Main.

Step2: Define the main method.

Step3: Create an array of type double and define its length value as 5.

Step4: Call the method to populate the array named fillArray.

Step5: Call the method to find minimum and maximum value in the array.

Step6: Define the fillArray method and implement it.

Step7: Use for-loop to store the array.

Step8: Display the input arguments.

Step9: Define the fillMaxMin method and declare the required variables.

Step10: Use another for-loop to compute and compare the minimum and maximum values in array

Step11: Display the highest and lowest value.


Step 2

Code(in java)-

//creating the application named MinMax

public class Main


   // defining the main method

   public static void main(String[] args)


       //create an array of type double

       //length is five

       double[] inputarray = new double[5];

       //calling the method to populate array


       //calling the method to find minimum and maximum in the array




   //Implementing the method to get the values

   //from the command line arguments

   private static void fillArray (String[] args,double[] inputarray)


       System.out.println("The input array is:");

       //Take the 5 arguments from command line from the user

       //and store them in the inputarray

       for(int k=0;k<args.length;k++)


           //converting from string to double


           //Display the input arguments

           System.out.print(args[k]+" ");




   //Implementing method to find minimum and maximum array

   public static void findMaxMin(double[] arr)
