Here we are going to write a program on conversion of Decimal To Octal Numbers in Java.

Decimal To Octal Conversion :

import java.util.Scanner;

public class ConvertDecimalToOctal {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter any Decimal Number : ");
        int input = sc.nextInt();
        System.out.println("Oct is : "+convertDecimalToOctal(input));
    }
    
    public static String convertDecimalToOctal(int decimal) {
        String octal = "";
        try {
            if (decimal != 0) {
                while (decimal > 0) {
                    octal = decimal % 8 + octal;
                    decimal /= 8;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {

        }
        return octal;
    }

}

Output :

Enter any Decimal Number :  156
Oct is : 234
