Reasons for inner classes

• More readable code

  • all information for how to handle the event is located in one file
  • for a novice this might be difficult to parse at first

• Better encapsulation

  • the inner class can be declared private and thus only accessible to its enclosing class
  • e.g. the connection to a database server can be captured as an inner class limiting the classes that can directly connect to the database, enforcing the connection protocol
  • one point of control!
