This Java program uses the java.util.Calendar class to find the first day and last day of the week. It begins by creating a Calendar object that represents the current date and time. The program sets the DAY_OF_WEEK field of the Calendar object to Calendar.MONDAY, effectively setting it to the first day of the current week. The first day of the week is then printed to the console using the getTime() method of the Calendar object.

To determine the last day of the week, the program adds 6 days to the Calendar object using the add() method with the DATE field. Afterward, the last day of the week is printed to the console. By following these steps, the program successfully finds and displays the first and last day of the week. It’s important to note that the Calendar class is part of the legacy java.util package.
