Java Program to Convert Floating Point Decimal to Octal Number

We can convert any decimal number to its equivalent octal number using the following program.

Here, we keep the reminder obtained by dividing the given number by the base of octal, and divide it by8, and then multiply each reminder by10to reverse the order of reminders stored. The following example lets us understand.

Example

public class DecimalToOctal {
　　　public static void main(String[] args) {
　　　　　　int decimal =　84;
　　　　　　int octalNumber = 0, i =　1;
　　　　　　while (decimal != 0) {
　　　　　　　　　octalNumber　+= (decimal %　8)　*　i;
　　　　　　　　　decimal　/=　8;
　　　　　　　　　i　*=　10;
　　　　　　}
　　　　　　System.out.println("Octal of given decimal is ");　+　octalNumber);
　　　}
}

Output Result

Octal of given decimal is　124
