   public static void main(String[] args)
   {
      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 = convertToOctal(decimal); 
      for(int x = a - 1; x > 0; x--)
      {
         System.out.print(oct[x]);
      }
      sc.close();
   }

   static int[] convertToOctal(int oct) 
   {
      int y[] = new int[50];
      while(oct != 0)
      {
         y[a++] = oct % 8;
         oct = oct / 8;
      }
      return y;
   }
}

Output:

Please enter a decimal number : 100
The octal number is : 144
