Question

write a program to input an integer number and find and print the smallest and largest digit of the number in java ​

Answer 1

// Java program to find and print the largest and smallest digit of a number

import java.util.*;  

import java.lang.*;  

import java.io.*;  

 

class digitLargeSmall  

{  

     

// Function to find the largest and smallest digit of a number  

static void digitFun(int n)  

{  

   int largest = 0;  

   int smallest = 9;  

    while(n != 0)  

   {  

       int r = n % 10;  

 

       // Find the largest digit  

       largest = Math.max(r, largest);  

 

      // Find the smallest digit

       smallest = Math.min(r, smallest);  

 

       n = n / 10;  

   }  

   System.out.println(largest + " " + smallest);

   System.out.println(---------------------------------);      

   System.out.println(largest + " " + smallest);  

}

Answer 2

Answer:

Step-by-step explanation:

import java.util.Scanner;

Class SmallestAndLargestNum

{

public static void main(String[ ] args)

{

Scanner scan=new Scanner(System.in);

int n=scan.nextInt();

int largest=0,smallest=9,rem;

while(n!=0)

{

rem=n%10;

if(largest<rem)

{

largest=rem;

}

else if(smallest>rem)

{

smallest=rem;

}

n=n/10;

}

System.out.println(largest+" : is the largest number");

System.out.println(smallest+" : is the smallest number");

}

}
