Answer:
Adrita Roy, I've been learning Java since middle school
Updated March 22, 2019
I have written the code. It might look complex, but it’s not.
I’ve considered two extra criteria ;
If the user inputs all same numbers
If the user inputs two same and one different number.
I have explained the working in comment lines.
Here’s the code that I’ve written.
import java.util.*;
class Num
{
void main()
{
Scanner sc=new Scanner(System.in);
int n1=0, n2=0, n3=0;
int small= 999, large= -999; // taking a random value for 'small' and 'large' variables for convenience in comparing
// Taking inputs using Scanner class
System.out.println("Enter 1st number");
n1=sc.nextInt();
System.out.println("Enter 2nd number");
n2=sc.nextInt();
System.out.println("Enter 3rd number");
n3=sc.nextInt();
//In order to find the largest and the smallest the numbers cannot be same. So I'm eliminating that option.
if(n1==n2 && n2==n3 && n3==n1)
System.out.println("Error! Numbers are equal");
else
{
/*It might happen that two numbers are equal while the third number is different. In that case I'm assigning an arbitrary value to one of the number(-99).The purpose of this is to avoid the condition of equality of any two numbers*/
if( n1==n2) n1= -99;
if(n2==n3) n2= -99;
if(n3==n1) n3= -99;
// *********MAIN CODE**********
/* Considering each number separately and comparing it with 'small' and 'large' variables which have values assigned by me
The condition of equality or repetition of numbers is eliminated from the code by the help of the'not equal to' (!=) condition */
if(n1!=-99)
{
if(n1> large)
large=n1;
if( n1<small)
small=n1;
}
//In case the number is different than the assumed values, 'large' and 'small' gets changed to n1 and thus n2 is compared with n1. Same for n3.
if(n2!=-99)
{
if(n2> large)
large=n2;
if( n2<small)
small=n2;
}
if(n3!=-99)
{
if(n3> large)
large=n3;
if( n3<small)
small=n3;
}
// Displaying the output
System.out.println (" Largest number : "+ large);
System.out.println (" Smallest number : "+ small);
}
}
}
