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: public FactLineBuilder setC_BPartner_ID_IfValid ( final int bpartnerId ) { assertNotBuild ( ) ; if ( bpartnerId

0 ) { setC_BPartner_ID ( bpartnerId ) ; } return this ; } Code After Refactoring 1: public FactLineBuilder bpartnerIdIfNotNull ( final BPartnerId bpartnerId ) { if ( bpartnerId != null ) { return bpartnerId ( bpartnerId ) ; } else { return this ; } } public FactLineBuilder setC_BPartner_ID_IfValid ( final int bpartnerRepoId ) { return bpartnerIdIfNotNull ( BPartnerId . ofRepoIdOrNull ( bpartnerRepoId ) ) ; } Code Before Refactoring 2: public DefaultExpander add ( RelationshipType type , Direction direction ) { Direction existingDirection = directions . get ( type . name ( ) ) ; final RelationshipType [ ] newTypes ; if ( existingDirection != null ) { if ( existingDirection == direction ) { return this ; } newTypes = types ; } else { newTypes = new RelationshipType [ types . length + 1 ] ; System . arraycopy ( types , 0 , newTypes , 0 , types . length ) ; newTypes [ types . length ] = type ; } Map < String , Direction

newDirections

new HashMap < String , Direction

( directions ) ; newDirections . put ( type . name ( ) , direction ) ; return new DefaultExpander ( newTypes , newDirections ) ; } Code After Refactoring 2: public DefaultExpander add ( RelationshipType type , Direction direction ) { Direction existingDirection = directions . get ( type . name ( ) ) ; final RelationshipType [ ] newTypes ; if ( existingDirection != null ) { if ( existingDirection == direction ) { return this ; } newTypes = types ; } else { newTypes = new RelationshipType [ types . length + 1 ] ; System . arraycopy ( types , 0 , newTypes , 0 , types . length ) ; newTypes [ types . length ] = type ; } Map < String , Direction

newDirections

new HashMap < String , Direction

( directions ) ; newDirections . put ( type . name ( ) , direction ) ; return ( DefaultExpander ) newExpander ( newTypes , newDirections ) ; } protected RelationshipExpander newExpander ( RelationshipType [ ] types , Map < String , Direction

directions ) { return new DefaultExpander ( types , directions ) ; } 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 java 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
