# Java: Find the difference between the largest integer and the smallest integer which are created by 8 numbers from 0 to 9

## Java Basic: Exercise-231 with Solution

Write a Java program to find the difference between the largest integer and the smallest integer. These integers are created by 8 numbers from 0 to 9. The number that can be rearranged starts with 0 as in 00135668.

**Input:**

Data is a sequence of 8 numbers (numbers from 0 to 9).

**Output:**

The difference between the largest integer and the smallest integer.

**Visual Presentation:**

**Sample Solution:**

**Java Code:**

```
// Importing necessary classes for input/output operations and array manipulation
import java.util.*;
// Main class named "Main"
public class Main {
// Main method to execute the program
public static void main(String[] args) {
// Creating Scanner object to read input from the user
Scanner sc = new Scanner(System.in);
// Prompting the user to input an integer created by 8 numbers from 0 to 9
System.out.println("Input an integer created by 8 numbers from 0 to 9:");
// Reading the input string
String s = sc.next();
// Initializing an array to store individual digits of the input integer
int[] num = new int[8];
// Extracting each digit from the input string and storing it in the array
for (int i = 0; i < 8; i++) {
num[i] = Integer.valueOf(s.substring(i, i + 1));
}
// Sorting the array in ascending order
Arrays.sort(num);
// Initializing variables to calculate the smallest and largest integers
int a = 0;
int b = 0;
int c = 1;
// Calculating the smallest and largest integers from the sorted array
for (int i = 0; i < 8; i++) {
a += num[i] * c;
b += num[7 - i] * c;
c *= 10;
}
// Outputting the difference between the largest and smallest integers
System.out.println("Difference between the largest and the smallest integer from the given integer:");
System.out.println(a - b);
}
}
```

Sample Output:

Input an integer created by 8 numbers from 0 to 9: 567894321 Difference between the largest and the smallest integer from the given integer: 75308643
