5 | | -In this approach, the different conditions for Bob’s responses are separated into dedicated private methods within the `Bob` class. This method-based approach improves readability and modularity by organizing each condition check into its own method, making the main response method easier to understand and maintain. |

7 | | -The main `hey` method determines Bob’s response by delegating each condition to a helper method (`isSilent`, `isYelling`, and `isAsking`), each encapsulating specific logic. |

9 | | -## Explanation |
10 | | - |
11 | | -This approach simplifies the main method `hey` by breaking down each response condition into helper methods: |
12 | | - |
13 | | -1. **Trimming the Input**: |
14 | | - The `input` is trimmed using the `String` [`trim()`][trim] method to remove any leading or trailing whitespace. This helps to accurately detect if the input is empty and should prompt a `"Fine. Be that way!"` response. |
15 | | - |
16 | | -2. **Delegating to Helper Methods**: |
17 | | - Each condition is evaluated using the following helper methods: |
18 | | - |
19 | | - - **`isSilent`**: Checks if the trimmed input has no characters. |
20 | | - - **`isYelling`**: Checks if the input is all uppercase and contains at least one alphabetic character, indicating shouting. |
21 | | - - **`isAsking`**: Verifies if the trimmed input ends with a question mark. |
22 | | - |
23 | | - This modular approach keeps each condition encapsulated, enhancing code clarity. |
24 | | - |
25 | | -3. **Order of Checks**: |
26 | | - The order of checks within `hey` is important: |
27 | | - - Silence is evaluated first, as it requires an immediate response. |
28 | | - - Shouted questions take precedence over individual checks for yelling and asking. |
29 | | - - Yelling comes next, requiring its response if not combined with a question. |
30 | | - - Asking (a non-shouted question) is checked afterward. |
31 | | - |
32 | | - This ordering ensures that Bob’s response matches the expected behavior without redundancy. |

119 | | -## Advantages of the Method-Based Approach |
120 | | - |
121 | | -- **Readability**: Each method is clearly responsible for a specific condition, making the main response logic easy to follow. |
122 | | -- **Maintainability**: Changes to a condition can be confined to its method, minimizing impacts on the rest of the code. |
123 | | -- **Code Reusability**: Helper methods can be reused or adapted easily if new conditions are added in the future. |
124 | | - |
125 | | -## Considerations |
126 | | - |
127 | | -- **Efficiency**: While this approach introduces multiple method calls, it enhances readability significantly, which is often more valuable in non-performance-critical applications. |
128 | | -- **Error Prevention**: This approach avoids redundant code, reducing the risk of maintenance errors. |

130 | | -## Shortening Condition Checks |
131 | | - |
132 | | -If each `if` statement body is only a single line, braces can be omitted, or the test expression and result could be placed on a single line. However, [Java Coding Conventions][coding-conventions] recommend always using curly braces for error prevention and easier future modifications. |
133 | | - |
134 | | -### Alternative: Inline Helper Methods |
135 | | - |
136 | | -For smaller projects, consider implementing helper methods inline or as lambdas, though this might reduce readability. |
