## Q. Java Program to Find the Sum of Digits in a Given Number.

Here you will find an algorithm and program in Java programming language to find the sum of digits in number. Now let us understand this.

Explanation : Suppose we are having number 12548 and we have to calculate the sum of digits in the given number, so here we have the following digits 1, 2, 5, 4, 8 and we will sum all these digits -> 1 + 2 + 5 + 4 + 8 and the result we get is 20 that will be our output.

## Sum Of Digits Algorithm

```START
Step 1: Get number by user
Step 2: Get the modulus/remainder of the number
Step 3: sum the remainder of the number
Step 4: Divide the number by 10
Step 5: Repeat the step 2 while number is greater than 0.
STOP
```

# Java Program to Find the Sum Of Digits in Number

```class LFC {
static int sum_digit(int num)
{
int sum = 0,rem;
while (num != 0) {
rem=num % 10;
num = num / 10;
sum=sum+rem;
}
return sum;
}

public static void main(String[] args)
{
int num = 123456;
System.out.print("Sum Of Digits : " + sum_digit(num));
}
}
```

#### Output

```Sum Of Digits : 21
```
