import java.util.Scanner;
public class DecimalToOctalExample
{
   static int octal[] = new int[50], x = 1;
   int[] convertToOctal(int oct)
   {
      if(oct != 0)
      {
         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);
      for(int a = x - 1; a > 0; a--)
      {
         System.out.print(oct[a]);
      }
      sc.close();
   }
}

Output:

Please enter a decimal number: 644
The octal number is : 1204
