Paper For Above instruction

The assignment for Week 2 involves developing two critical methods in Java, focusing on testing and debugging practices as outlined in Chapter 3 of "Data Structures: Abstraction and Design Using Java." These tasks emphasize the importance of robust code development with appropriate exception handling and the application of test-driven development (TDD) methodologies to ensure code correctness.

Implementing a Search Method with Exception Handling

The first task requires creating a search method that accepts four parameters: an array to be searched, a target value, a starting index, and a finishing index that denote the portion of the array to be examined. This method must incorporate exception handling to manage potential errors such as invalid indices or null array references. Proper validation should be performed to ensure that the start and finish indices are within bounds of the array, and that the array itself is not null. If invalid inputs are detected, appropriate exceptions should be thrown to alert the calling code of the issues.

The search algorithm itself can be implemented as a linear search within the specified subarray boundaries. The process involves iterating through the array from the start index to the finish index, comparing each element to the target value. If a match is found, the index is returned; otherwise, the method indicates that the target was not found, perhaps by returning a sentinel value such as -1.

This method demonstrates essential debugging and validation skills, ensuring that the code is resilient against invalid inputs and that exceptions are properly managed, aligning with best practices in software development.

Developing the findLargest Method Using Test-Driven Development

The second task involves creating the findLargest method, which identifies the maximum value in an array segment. This method must be developed using Test-Driven Development (TDD), a rigorous approach where tests are written before the implementation code. TDD promotes code correctness by ensuring that each method passes predefined test cases that verify its functionality under various conditions.

Initially, test cases should be designed to cover typical scenarios, such as arrays with positive numbers, negative numbers, and mixed values, as well as edge cases like empty arrays or null references. These tests will determine the expected output for each input scenario. Once the tests are in place, the findLargest method can be incrementally developed to pass all tests, starting from the simplest cases and gradually handling more complex situations.

Functionality-wise, the method will iterate through the array section, tracking the largest value encountered. It will return this value after completing the traversal. If the array segment is invalid or empty, appropriate exceptions or return values should be integrated according to TDD best practices.

This approach ensures that the implementation is reliable, maintainable, and free of bugs, exemplifying professional programming standards.

Conclusion

Overall, these tasks represent fundamental exercises in developing safe, testable, and reliable code. Proper exception handling and TDD are essential skills that improve code quality and facilitate debugging. By completing these exercises, students will strengthen their understanding of testing methodologies, exception management, and algorithm implementation, which are vital competencies in professional software development.
