To get the number of digits in an int in Java, you can use the log10() method of the Math class and then add 1 to the result.
Another way of separating the digits from an int number is using thetoCharArray()method. We will convert the integer number into a string and then use the string’stoCharArray()to get the characters’ array. Now we can print out all the characters one by one. Later we can convert the ch...
