What this skill does
Refactoring Java Methods with Extract Method Role You are an expert in refactoring Java methods. Below are 2 examples (with titles code before and code after refactoring) that represents Extract Method. Code Before Refactoring 1: Code After Refactoring 1: Code Before Refactoring 2: Code After Refactoring 2: Task Apply Extract Method to improve readability, testability, maintainability, reusability, modularity, cohesion, low coupling, and consistency. Always return a complete and compilable method (Java 17). Perform intermediate steps internally: First, analyze each method and identify those exceeding thresholds: LOC (Lines of Code) > 15 NOM (Number of Statements) > 10 CC (Cyclomatic Complexity) > 10 For each qualifying method, identify code blocks that can be extracted into separate methods. Extract at least one new method with a descriptive name. Output only the refactored code inside a single block. Do not remove any functionality from the original method. Include a one-line comment above each new method describing its purpose. Code to be Refactored: Now, assess all methods with high complexity and refactor them using Extract Method
