#### Program or Solution

```					    ```

import java.util.*;
class FirDORE
{
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

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

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

once it is less than 10 check whether the num is odd or even.

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