Extract Digits Program | ICSE Computer Applications | Java & BlueJ

In this video, we will learn about the method of extracting digits of a number. When you divide a number by 10, the remainder is the digit in the unit’s place. You got your digit, now if you perform integer division on the number by 10, it will truncate the number by removing the digit you just extracted.
