# Java: Compute the digit number of sum of two given integers

## Java Basic: Exercise-212 with Solution

Write a Java program to compute the digit number of the sum of two given integers.

**Input: **

Each test case consists of two non-negative integers a and b which are separated by a space in a line. 0 ≤ a, b ≤ 1,000,000

**Visual Presentation:**

**Sample Solution:**

**Java Code:**

```
import java.util.*;
public class Main {
public static void main(String[] args) {
// Prompting the user to input two integers (a and b)
System.out.println("Input two integers(a b):");
// Creating a Scanner object for user input
Scanner stdIn = new Scanner(System.in);
// Reading the values of integers a and b from user input
int a = stdIn.nextInt();
int b = stdIn.nextInt();
// Calculating the sum of integers a and b
int sum = a + b;
// Initializing a variable to count the number of digits in the sum
int count = 0;
// Counting the number of digits in the sum using a while loop
while (sum != 0) {
sum /= 10;
++count;
}
// Displaying the digit number of the sum of the two integers
System.out.println("Digit number of sum of said two integers:");
System.out.println(count);
}
}
```

Sample Output:

Input two integers(a b): 13 25 Digit number of sum of said two integers: 2
