#### Program or Solution

```
```
import java.util.*;
class Checker
{
public static void main(String args[])
{
int num;
Scanner sc=new Scanner(System.in);
System.out.println("Enter The Number:");
num=sc.nextInt();
while(num>=10)
{
num=num/10;
}
if(num%2==0)
{
System.out.println("The First Digit Is Even.");
}
else
{
System.out.println("The First Digit Is Odd.");
}
}
}

#### Program Explanation

1. Get num (to which first digit is to be identified)

2. Instruction(s) inside the while block{} are executed repeatedly till expression (num>=10) is true.

3. Divide the number num by 10 untill it becomes lesser than 10.

once it is less than 10, check whether the number is even

if even, print even. else print odd.

statement num = num/10 divides the num by 10 repeatedly until it num is less than 10

Example

487

487/10 = 48

48 / 10 = 4

4 is less than 10, so check whether 4 is even.

4 is even, so print even.
