Two Smallest (20 points). Write a program TwoSmallest. java that takes a set of double command-line arguments and prints the smallest and second-smallest number, in that order. It is possible for the smallest and second-smallest numbers to be the same (if the sequence contains duplicate numbers). Note: display one number per line. Hint: Double. MAX_VALUE is the largest real number that can be stored in a double variable. java TwoSmallest 17.0 23.0 5.0 1.1 6.9 0.3 0.3 1.1 java TwoSmallest 1.0 35.0 2.0 1.1 6.9 0.3 0.3 6.7 0.3 0.3

Written in Java

import java.util.*;

public class Main {

   public static void main(String args[]) {

     int n;

     Scanner input = new Scanner(System.in);

     n = input.nextInt();

     double nums []= new double [n];

     for (int i=0; i<n;i++)

     {

         nums[i] = input.nextDouble();

     }

     Arrays.sort(nums);

     System.out.println("The two smallest are: ");

     for (int i=0; i<2;i++)

     {

         System.out.println(nums[i]);

     }

   }

}

Explanation:

This line declares number of input

     int n;

This line calls the Scanner function

     Scanner input = new Scanner(System.in);

This line gets input from user

     n = input.nextInt();

This line declares an array of n elements

     double nums []= new double [n];

The following iteration gets input into the array

     for (int i=0; i<n;i++)

     {

         nums[i] = input.nextDouble();

     }

This line sorts the array

     Arrays.sort(nums);

The following iteration prints the two smallest

     System.out.println("The two smallest are: ");

     for (int i=0; i<2;i++)

     {

         System.out.println(nums[i]);

     }

i think so.
