The Prompt
Create a Java function that adjusts a given datetime based on a specified custom day end time.
The function should take two parameters:
– A datetime object (of type `LocalDateTime` or `ZonedDateTime`)
– A custom day end time (of type `LocalTime`)
The function will return the adjusted datetime.
**Behavior:**
– If the input datetime is before the custom day end, return the original datetime.
– If the input datetime is after the custom day end, calculate the difference and adjust the datetime to the custom day end accordingly.
– Ensure to handle scenarios where the custom day end is on the next day.

How to Use This Prompt
- Copy the prompt provided above.
- Open your preferred coding environment.
- Create a new Java file or project.
- Paste the prompt into your code editor.
- Implement the Java function as described.
- Test the function with various datetime inputs.
Tips for Best Results
- Define the Function: Create a method that accepts a `LocalDateTime` or `ZonedDateTime` and a `LocalTime` as parameters.
- Check Time Condition: Use an if-statement to compare the input datetime with the custom day end time.
- Adjust Datetime: If the datetime is after the custom end time, calculate the adjustment needed and set the datetime to the custom end time, possibly moving to the next day.
- Return Result: Ensure the function returns the original datetime if it’s before the custom end time, or the adjusted datetime if it’s after.
