Question ➡️ 5 Finger Rule in Java

1. Use Arrays for Fixed Size Data:

Just as your fingers have a predefined structure, arrays are ideal for data of fixed size. Arrays allocate memory in a contiguous block, making them efficient for data that doesn’t change in size frequently.

Use arrays for collections of similar data types where the length won’t change dynamically. For more flexible sizing, consider ArrayLists or other data structures.

2. Avoid Empty Catch Blocks:

Imagine your fingers slipping when trying to grasp
something important. Similarly, empty catch blocks in your code can lead to dropped errors or unnoticed issues.

When an exception is caught, handle it appropriately. If you’re not sure how to handle it, at least log the exception. Leaving catch blocks empty can mask problems, making debugging a nightmare.

3. Always Handle Exceptions:

Handling exceptions is like being prepared for unexpected detours on a journey. Always use try-catch blocks to catch potential exceptions.

Failing to handle exceptions can lead to crashes and disruptions in your program’s flow. Handle exceptions gracefully by providing meaningful error messages or taking appropriate actions.

4. Beware of Array Index Out of Bounds:

Just as using your fingers beyond their reach can cause discomfort, accessing arrays beyond their bounds leads to errors. ArrayIndexOutOfBoundsException occurs when trying to access an index that’s outside the array’s valid range.

Always ensure you’re within the array’s bounds when accessing elements to prevent runtime crashes.

5. Keep Dependencies Minimal:

Your fingers work best when they’re free from unnecessary attachments. Similarly, your Java programs perform optimally when you keep external dependencies to a minimum. While libraries and frameworks are useful, avoid adding more than what’s necessary. This minimizes the risk of compatibility issues, simplifies maintenance, and keeps your codebase tidy.
