What would the .java file look like? Please show with explanation. I will take care of header documentation.

What Your Program Will Do For this program, you will input three pieces of a date as int data: a month, a day, and a year If the date is valid, calculate and output the day of the year. The calculation will need to take into account leap years, meaning that 12/31/2018 would be day of year 365 whereas 12/31/2020 would be day of the year 366 because of the extra day for February 29th, 2020. A valid date needs to satisfy the following requirements: . The month needs to be between 1 and 12, inclusive. . The day needs to be appropriate for the month. For example, the day should be between 1 and 31 for March or between 1 and 30 for September. The day should be between 1 and either 28 or 29 depending on if the year is a leap year. . The year needs to be between 1800 and 3000, inclusive. After the date information has been read from the user, print a single blank line and then one of the following two results. If the date is valid, process and calculate the day of the year and output the results in the following format: Day of the year: 36 Remaining days: 329 If the date is invalid for any reason, output an error message in the following format, with month and day padded with o sto be at least two digits and year padded with 0 s for four digits: INVALID DATE: -2/01/2000 INVALID DATE: 04/91/9010
