Java Program to Extract Digits from a Given Number

This is a Java Program to Extract Digits from A Given Integer.

Enter any integer as input. After that we perform several operations like modulus and division to know the number of digits in given integer and then print each of the digits of the given number.

Here is the source code of the Java Program to Extract Digits from A Given Integer. 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 Extract_Digits 
```
```
{
```

    public static void main(String args[])

```
    {
```

        int n, m, a, i = 1, counter = 0;

        Scanner s=new Scanner(System.in);

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

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

            System.out.println("Digits at position "+counter+":"+a);

```
            m = m / 10;
```
```
            counter--;
```
```
        }
```
```
    }
```
```
}
```

Output:

$ javac  Extract_Digits.java
$ java  Extract_Digits
 
Enter any number:5678
Digits at position 4:8
Digits at position 3:7
Digits at position 2:6
Digits at position 1:5
