Detailed explanation-1: -To convert decimal to octal numbers, the octal dabble method is used. In this method, the decimal number is divided by 8 each time, it yields or gives a remainder. The first remainder we get is the least significant digit(LSD) and the last remainder is the most significant digit(MSD).
Detailed explanation-2: -Java Octal to Decimal conversion: Integer. parseInt() method converts a string to an int with the given radix. If you pass 8 as a radix, it converts an octal string into decimal. Let us see the signature of parseInt() method: public static int parseInt(String s, int radix)
Detailed explanation-3: -The octal numbering system uses the numerals 0-1-2-3-4-5-6-7. In computing environments, it is commonly used as a shorter representation of binary numbers by grouping binary digits into threes. The chmod command in Linux or UNIX uses octal to assign file permissions.
