URL: https://github.com/apache/commons-lang/pull/1269
This pull request introduces the `isPrime` method to the `NumberUtils`
class, enhancing its functionality to include prime number detection.
**Why This Change?**
The addition of the `isPrime` method fulfills a common requirement in
various applications where checking for prime numbers is needed. Prime number
detection is useful in numerous scenarios such as cryptographic algorithms,
data validation, and mathematical computations. By incorporating this method
into `NumberUtils`, users can leverage a well-tested, reliable implementation
directly from the utility library.
**Changes Made:**
- **Feature Addition:**
- Implemented the `isPrime` method in `NumberUtils.java`, providing a
straightforward way to determine if a number is prime.
- **Test Coverage:**
- Added comprehensive test cases for the `isPrime` method in
`NumberUtilsTest.java`.
- Tests include a variety of inputs, such as positive prime numbers,
non-prime numbers, and edge cases like zero and negative numbers.
**Benefits:**
- **Enhanced Functionality:** Users now have access to a prime number
checking utility within the `NumberUtils` class.
- **Reliability:** The method has been thoroughly tested to ensure accurate
results and robust performance.
- **Convenience:** Integrates seamlessly into existing codebases using the
`NumberUtils` class, reducing the need for external libraries or custom
implementations.
**Example Usage:**
```java
// Check if a number is prime
boolean result = NumberUtils.isPrime(11); // true
boolean result = NumberUtils.isPrime(20); // false
```
**Additional Notes:**
- > The implementation follows the project's coding standards and has been
validated against all relevant test cases.
- > All tests have passed successfully, ensuring that the new method
integrates smoothly with the existing codebase.
- > Please review the proposed changes and let me know if further
modifications are needed. Thank you for considering this enhancement!
