# Java Exercises: 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 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

Pictorial Presentation: Sample Solution:

Java Code:

``````import java.util.*;
public class Main
{
public static void main(String[] args)
{
System.out.println("Input two integers(a b):");
Scanner stdIn = new Scanner(System.in);
int a = stdIn.nextInt();
int b = stdIn.nextInt();
int sum = a + b;
int count = 0;
while(sum != 0)
{
sum /= 10;
++count;
}
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
```

## Java: Tips of the Day

Java: Anagrams

Generates all anagrams of a string.

```public static List<String> anagrams(String input) {
if (input.length() <= 2) {
return input.length() == 2
? Arrays.asList(input, input.substring(1) + input.substring(0, 1))
: Collections.singletonList(input);
}
return IntStream.range(0, input.length())
.mapToObj(i -> new SimpleEntry<>(i, input.substring(i, i + 1)))
.flatMap(entry ->
anagrams(input.substring(0, entry.getKey()) + input.substring(entry.getKey() + 1))
.stream()
.map(s -> entry.getValue() + s))
.collect(Collectors.toList());
}
```
