What are the applications of todo in Java?

In Java, TODO is commonly used to temporarily mark sections of code that need to be completed or fixed. Here are some common use cases for TODO:

1. Marking features or tasks that need to be completed: When writing code, there may be times when certain features are not yet implemented or need further improvement. In these cases, you can use TODO to mark these sections so you can come back later to continue refining them.
2. Identifying code for optimization: Sometimes there may be inefficient or unoptimized areas in the code, which can be marked with TODO for later optimization.
3. Identify bugs that need to be fixed: If bugs are found in the code but cannot be fixed immediately, they can be temporarily marked with TODO for later repair.
4. To mark the code that needs to be refactored: Sometimes the structure of the code may not be clear or easy to read, you can use TODO to mark the parts that need to be refactored, so that the code structure can be optimized later.
5. Mark the document comments that need to be added: When writing code, there may be methods or classes that do not yet have complete document comments. TODO can be used to mark these sections for later addition of document comments.
