Problems

Use the following problems to test your programming prowess on date and time. I strongly encourage you to give each problem a try before you turn to the solutions and download the example programs:

1. Defining a day period: Write an application that goes beyond AM/PM flags and split the day into four periods: night, morning, afternoon, and evening. Depending on the given date-time and time zone generate one of these periods.
2. Converting between Date and YearMonth: Write an application that converts between java.util.Date and java.time.YearMonth and vice-versa.
3. Converting between int and YearMonth: Let's consider that a YearMonth is given (for instance, 2023-02). Convert it to an integer representation (for instance, 24277) that can be converted back to YearMonth.
4. Converting week/year to Date: Let's consider that two integers are given representing a week and a year (for instance, week 10, year 2023). Write a program that converts 10-2023 to a java.util.Date via Calendar...
