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).

The following code is written in java programming language:

public class TwoSmallest {   //define class

   public static void main(String[] args) {     // define main function

       if (args.length < 2) {     //set the if condition

           System.out.println("Enter double values as command line arguments");

       } else {

           double minimum1 = Double.parseDouble(args[0]), minimum2 = Double.parseDouble(args[1]), n;

           if (minimum1 > minimum2) {    //set the if condition

               double temp = minimum1;

               minimum1 = minimum2;

               minimum2 = temp;

           }

           for (int i = 2; i < args.length; i++) {      //set the for loop

               n = Double.parseDouble(args[i]);

               if (n < minimum1) {

                   minimum2 = minimum1;

                   minimum1 = n;

               } else if (n < minimum2) {

                   minimum2 = n;

               }

           }

           System.out.println(minimum1);

           System.out.println(minimum2);

       }

   }

}

Explanation:

Here, we define a class "TwoSmallest" with public modifier.

Then, we define the main method.

Then, we set if condition and pass condition "args.length < 2".

Then we take three double type variable "minimum1", "minimum2" and "n".

Then, we set the if condition and pass condition if "minimum1 > minimum2", then set double type "temp" variable and swap between temp, minimum1 and minimum2.

Then, we set the for loop which is start from 2 and stops at "args.length"

Then, we set if condition and then we set its else part, after that we print the value of minimum1 and minimum2.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
