Answer:
I would need the complete code or a detailed explanation of the specific methods and their intended functionality.
However, I can provide some general guidance on implementing TODO methods in Java:
1. Understand the requirements:
Read the comments and understand the purpose of the TODO methods. Identify what needs to be implemented and any specific instructions or requirements mentioned in the comments.
2. Define the method signature:
Determine the return type, method name, and parameters based on the requirements of the TODO method.
3. Implement the functionality:
Write the code inside the TODO method to achieve the desired functionality. This may involve performing calculations, manipulating data structures, calling other methods, or any other necessary operations.
4. Test the implementation:
After writing the code, test the TODO method to ensure that it produces the expected results. You can write test cases or use existing test cases to verify the correctness of the implementation.
If you can provide the actual code or more specific details about the TODO methods, I would be happy to assist you further with their implementation and provide a more specific explanation.
