Math Class Function In Java

 In this task, you are being asked to apply Math class functions.
Write a program that computes the first and last digit of a number. For example, if the input is
23456, the program should print 2 and 6.
Hint: Use % and Math.log10.

Code:

import java.util.Scanner;

public class Lab4Task4{

public static void main(String[] args) {

Scanner Ahsan = new Scanner(System.in);

int firstDigit, lastDigit, num;

System.out.print("Enter the number: ");

num = Ahsan.nextInt();

firstDigit = num / (int) Math.pow(10, (int) Math.log10(num));

lastDigit = num % 10;

System.out.println("Input number: " + num);

System.out.println("First Digit is: " + firstDigit);

System.out.println("Last Digit is: " + lastDigit);

}

}

OutPut:
