In this guide, we will learn about these visibility modifiers with the help of examples. In kotlin we have four visibility modifiers – public, private, protected and internal. Overall, it’s important to use nested and inner classes in a balanced and appropriate way to take advantage of their benefits while avoiding their disadvantages.Visibility modifiers restrict the access of classes, interfaces, functions, properties, constructors etc.Debugging: Debugging nested and inner classes can be challenging, especially if there are multiple levels of nesting or if inner classes are used excessively.

Performance: Using nested and inner classes can slow down the performance of your code, especially if they are heavily used or if they are nested to many levels deep.Complexity: Adding nested and inner classes can make the code more complex and harder to understand, especially if there are multiple levels of nesting or if inner classes are used excessively.Accessibility: Inner classes have access to the members of the outer class, making it easier to share data between them and reducing code duplication.ĭisadvantages of using nested and inner classes in Kotlin:.Reusability: Nested and inner classes can be reused within the same class or across multiple classes, making it easier to write more maintainable code.Encapsulation: Nested and inner classes allow you to group related functionality together and keep it separate from the rest of the code, improving code organization and readability.Output: Outer class property accessed successfully from inner class Advantages or Disadvantages: Advantages of using nested and inner classes in Kotlin: ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.DevOps Engineering - Planning to Production.Python Backend Development with Django(Live).Android App Development with Kotlin(Live).Full Stack Development with React & Node JS(Live).
