Question & Answer: Write a program that displays the middle value of three unduplicated input values. Consider how easy or…..

import java.util.Scanner;

public class StatisticsDemo {

public static void main(String[] args) {

//initiating the scanner

Scanner sc = new Scanner(System.in);

System.out.println(“Enter value 1:”);

//taking input of the first element

int a = sc.nextInt();

System.out.println(“Enter value 2:”);

//taking input of the second element

int b = sc.nextInt();

System.out.println(“Enter value 3:”);

//taking input of the third element

int c = sc.nextInt();

//Calling the method “middle” where we are passing the three values as input

//and the method returns the middle value and storing the variable “middle”

int middle = middle(a, b, c);

System.out.println(“The middle value is : “+middle);

}

/*

* What iam trying to do is to sort the elements in increasing order

* So that the second number will be the median

* You can say that it is a mini version of selection sort

*/

private static int middle(int a, int b, int c) {

// effectively sort the values a, b & c

// putting smallest in a, median in b, largest in c

//intialising a variable to store values temporarily

int t;

/*comparing a and b if a>b then we are swapping the values of and b

* for example if a=6 , b=4 & c=5

* sinc a>b we are swapping the values as a=4 and b=6 now values are a=4,b=6,c=5

* then we check b>c since b>6 we swap the values

* now they are a=4,b=5,c=6

* then we check a>b again since the value of c is stored in b now

* if a>b we swap else the values will be same

* in our example a<b so the values are not swapped

* everytime the value will be in the variable b since we are sorting them in increasing order

*/

if (a > b) {

// swap a & b

t = a;

a = b;

b = t;

}

if (b > c) {

// swap b & c

t = b;

b = c;

c = t;

if (a > b) {

// swap a & b

t = a;

a = b;

b = t;

}

}

// b always contains the median value

return b;

}

}

Output:
