{
  octal[x++] = oct % 8;
oct = oct / 8;
convertToOctal(oct);
}
return octal;
}

public static void main(String[] args)
{
DecimalToOctalExample dto = new DecimalToOctalExample();
int decimal;
Scanner sc = new Scanner(System.in);
System.out.println("Please enter a decimal number: ");
decimal = sc.nextInt();
System.out.println("The octal number is : ");
int oct[] = dto.convertToOctal(decimal);
