Question

Write a program for the following.

Create an array DW[ ] of type double and size 8 and fill it with variables. Calculate the average of the maximum and the minimum element.

For example:

Input	30.8	27.5	18.2	35.2	21.1	25.6	8.8	9.4
Output	Max = 35.2		Min = 8.8		Average = 22.0

Answer 1

import java.util.Scanner;
public class CalculateAverage 
{
    public static void main(String[] args) 
    {
        double DW[] = new double[8];
        Scanner sc = new Scanner(System.in);
        
        System.out.println("Enter 8 double elements:");
        for (int j = 0; j < DW.length; j++) 
        {
            DW[j] = sc.nextDouble();
        }
        double max = DW[0];
        double min = DW[0];
        
        for (int j = 1; j < DW.length; j++) 
        {
            if (DW[j] > max) 
            {
                max = DW[j];
            }
            if (DW[j] < min) 
            {
                min = DW[j];
            }
        }
        
        double average = (max + min)/2.0;
        System.out.println("Max =" + max);
        System.out.println("Min =" + min + "\tAverage =" + average);
                sc.close();
    }
}
