Question

Write a program to accept 3 digit number and display the reverse of the number. Eg: Input number =345 Output number=543

Answer 1

Answer:

It can be easily done if you convert it to String and then use StringBuffer... I will do it by two methods:

1st: (without using string)

import java.util.Scanner;

class Reverse{

public static void main (String args[]){

Scanner sc = new Scanner (System.in);

System.out.println("Enter the number");

int n = sc.nextInt();

int result = 0 ;

while(n>0){

result = result*10 + n%10;

n=n/10;

}

System.out.println("The reversed number is "+result);

}

}

2nd: (using strings)

import java.util.Scanner;

import java.util.StringBuffer;

class Reverse{

public static void main (String args[]){

Scanner sc = new Scanner (System.in);

System.out.println("Enter the number");

int n = sc.nextInt();

StringBuffer num = new StringBuffer(n.toString());

num = num.reverse();

int result = Integer.parseInt(num.toString());

System.out.println("The reversed number is "+result);

}

}
