Step 2: Create two variables firstDigit and lastDigit and initialize them by 0.
Step 3: Use modulo operator(%) to find last digit.
Step 4: Use either while loop and division operator (/) or log() and pow() methods of Math class to find
.

{
int number = 502356997;
int firstDigit = 0;

lastDigit = number%10;
System.out.println("Last digit: "+lastDigit);
while(number!=0) {
firstDigit = number%10;
number /= 10;
}
