Question

Question 3 - If Statements - Intermediate

Put your ducks in a row. If ye dare.

Boolean comparisons provide the basis for that entire (critically important) 'sorting' category of operations (specifically, comparison sorting). Comparison sorts are those methods of organizing data in which one element is compared against another, and the relative position of one or both elements is determined by the comparison result.

TASK:

Based upon the following code:

import java.util.Scanner; // Import the Scanner class public class Main {   public static void main( String[] args ) {     Scanner myInput = new Scanner(System.in); // Create a Scanner object     System.out.println("Enter (3) digits: ");     int W = myInput.nextInt();     int X = myInput.nextInt();     int Y = myInput.nextInt();      } }

Use the tools described thus far to create additional code that will sort the integers in either monotonic ascending or descending order. Copy your code and output below:

import java.util.Scanner; // Import the Scanner class public class Main {   public static void main( String[] args ) {     // Create a Scanner object     Scanner myInput = new Scanner(System.in);     // Accept the user's input     System.out.println("Enter (3) digits: ");     int W = myInput.nextInt();     int X = myInput.nextInt();     int Y = myInput.nextInt();     // <TODO> - Sort the integers     int first = 0;     int second = 0;     int third = 0;     // Report the sorted numbers     System.out.println( "The sorted values are:" );     System.out.println( first + " " + second + " " + third);   } }

Answer 1

import java.util.Scanner; // Import the Scanner class

public class Main {

public static void main( String[] args ) {

    // Create a Scanner object

    Scanner myInput = new Scanner(System.in);

    // Accept the user's input

    System.out.println("Enter (3) digits: ");

    int W = myInput.nextInt();

    int X = myInput.nextInt();

    int Y = myInput.nextInt();

    // Sort the integers

    int first = 0;

    int second = 0;

    int third = 0;
  
    if(W<X){
        if(W<Y){
            first = W;
            if(X<Y){    // W<X<Y
                second = X;
                third = Y;
            }
            else{       // W<Y<=X
                second = Y;
                third = X;
            }
        }
        else{           // Y<=W<X
            first = Y;
            second = W;
            third = X;
        }
    }
    else if(X<Y){
        first = X;
        if(W<Y){        // X<=W<Y
            second = W;
            third = Y;
        }
        else{           // X<Y<=W
            second = Y;
            third = W;
        }
    }
    else{               // Y<=X<=W
        first = Y;
        second = X;
        third = W;
    }

    // Report the sorted numbers

    System.out.println( "The sorted values are:" );

    System.out.println( first + " " + second + " " + third);

}

}
