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

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
```
