Question

Need the second method as shown in the picture, which returns the reformatted date in Julian format.

### Julian Day Calculation in Programming

#### Method: `getJulianDay(int m, int d, int y)`

- **Purpose:** Returns the Julian day (ranging from 001 to 365/366) for the specified date, formatted as month/day/year.
- **Details:**
  - Ensure that leading zeroes are included so that the day value occupies three positions.
  - Account for leap years in your calculations.

#### Method: `getJulianFormat(int[] datePieces)`

- **Purpose:** Reformats a date into the Julian format.
- **Parameters:** `datePieces`, an array where:
  - Month is at position 0.
  - Day is at position 1.
  - Year is at position 2.
- **Returns:** A `String` formatted as `YYYYddd`.
  - `ddd` is the Julian day for the date.
  - Use the `getJulianDay` method to obtain `ddd`.

These methods help in converting Gregorian calendar dates into Julian day numbers, a common requirement in various scientific and programming contexts.
