Refactoring of code done to address some design smells and implementation smells.

Implementation smells fixed:

1. Complex Conditional: getBoolean method in JSONArray.
   Techniques: Extract Method, Decompose Conditional, Introduce Explaining Variable
   • Extract Method - Created isFalse() and isTrue() methods to handle the complex conditionals
   • Decompose Conditional - Broke down the complex if-conditions into simpler methods
   • Introduce Explaining Variable - Used isBooleanString to clarify the string check logic

2. Complex Conditional: nextTo method in JSONTokener
   Techniques: Extract Method, Decompose Conditional, Introduce Explaining Variable
   • Extract Method - Created isDelimiter() helper methods to encapsulate delimiter checks
   • Decompose Conditional - Broke down complex OR conditions into simpler checks
   • Introduce Explaining Variable - Used isEndOfInput to clarify the zero-character check

3. Magic Number: toString method in JSONArray
   Techniques: Introduce explaining variable
   • Introduce explaining variable (for magic number 2) - Explain the multiplier purpose
   • Introduce explaining variable (for magic number 16) - Explain minimum buffer size

Design smells fixed:

1. Deficient Encapsulation in JSONMLParserConfiguration
   Technique: Move Field/Method
2. Cyclical Dependency between XML and XMLTokener
   Technique: Extract Class
3. Missing Hierarchy of method similar in JSONArray, JSONObject and JSONString
   Technique: Replace conditional with Polymorphism
4. Broken Hierarchy between JSONStringer and JSONWriter
