Java Program to Reverse a Number and Find its Sum using do-while Loop

This is a Java Program to Reverse a Number and find the Sum of its Digits Using do-while Loop.

Enter any integer as an input. After that we use operations like modulus and division to reverse a number and find sum of its digits along with the help of do-while loop.

Here is the source code of the Java Program to Reverse a Number and find the Sum of its Digits Using do-while Loop. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
import java.util.Scanner;
```
```
public class Use_Do_While
```
```
{
```

    public static void main(String[] args)

```
    {
```
```
        int n, a, m = 0, sum = 0;
```

        Scanner s = new Scanner(System.in);

        System.out.print("Enter any number:");

```
        n = s.nextInt();
```
```
        do
```
```
        {
```
```
            a = n % 10;
```
```
            m = m * 10 + a;
```
```
            sum = sum + a;
```
```
            n = n / 10;
```
```
        }
```
```
        while( n > 0);
```

        System.out.println("Reverse:"+m);

        System.out.println("Sum of digits:"+sum);

```
    }
```
```
}
```

Output:

$ javac Use_Do_While.java
$ java Use_Do_While
 
Enter any number:456
Reverse:654
Sum of digits:15
