Advantages:<\/p>\n

    \n
  1. Inner classes have access to private members of outer classes, thus expanding the functionality of the outer class.<\/li>\n
  2. Inner classes can implement interfaces, inherit abstract classes, and increase flexibility.<\/li>\n
  3. Inner classes can hide implementation details, enhancing the encapsulation of the code.<\/li>\n
  4. Inner classes can easily access the properties and methods of the outer class, reducing the amount of code.<\/li>\n<\/ol>\n

    Drawbacks:<\/p>\n

      \n
    1. Inner classes add complexity to the code and reduce readability.<\/li>\n
    2. The creation of inner class objects requires the creation of outer class objects, which increases code coupling.<\/li>\n
    3. The scope of inner classes is limited to the outer class and they cannot be instantiated separately outside the outer class.<\/li>\n
    4. Inner classes increase the number of classes, which may result in the compiled bytecode file being too large.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
