Write your code in the file TwoSmallest.java. We wish to write a program that takes a set of numbers and determines which are the two smallest. Ask the user for the following information, in this order: A terminating value (real number). The user will enter this value again later, to indicate that he or she is finished providing input. A sequence of real numbers. Keep asking for numbers until the terminating value is entered. Compute and output the smallest and second-smallest real number, in that order. It is possible for the smallest and second-smallest numbers to be the same (if the sequence contains duplicate numbers).

Example

In ALL cases of error on input, RE-ASK the user for the input until it is correctly entered.

Solution

Code:

//TwoSmallest.java

import java.io.*;

import java.lang.*;

import java.util.*;

public class TwoSmallest

{

   //main

    public static void main(String[] args)

    {

              //Scanner object

              Scanner mySan=new Scanner(System.in);

              //Declare term

              float term;

              //Get the terminating value

              while(true)

              {

                   //Get term

                   term=mySan.nextFloat();

//Check user has entered terminating value. If not, print error-msg

                   if(term!=123)

                   {

                        //printing error-msg

System.out.println(\"Enter the terminating value to start the process\");

                 }

                 //user has entered terminating value

                   else

                        //exit from loop

                        break;

              }

       

              //Declare previous and current small element

              float prevSmall=term;

              float currSmall=term;

              //Loop to get set of nos.

              while(true)

              {

                   //Get no

                   float no=mySan.nextFloat();

//Check if user has entered terminating-value

                        if(no==123)

                             //If so, exit from loop

                             break;

//Otherwise, check if no is lemySan than current smallest element

                        if(no<currSmall)

                      {

                             //Assign currSmall to prevSmall

                             prevSmall=currSmall;

                             //Set currSmall to no

                             currSmall=no;

              

                        }               

             }

             //Print currSmall and prevSmall

             System.out.println(\"RESULT: \"+ currSmall);

             System.out.println(\"RESULT: \"+ prevSmall);

       

    }

   

}

Sample output:

123

17

23.5

15.2

10

30

8

16

123

RESULT: 8.0

RESULT: 10.0
