It’s almost 2020 and yet… Checked Exceptions are still a thing

In theory, there is no difference between theory and practice. In practice, there is.

  • Exposing Implementation Details in the Signature
  • No Appropriate Handling Possible (In some cases)
  • No Recovery Possible (In some cases)
  • Java 8 Lambdas and Streams
  • Always catch all checked exceptions at source and rethrow them as LogRuntimeException.
  • All of my methods do not declare any exceptions
  • As I discover that I need to deal with a specific exception I go back to the source where LogRuntimeException was thrown and I change it to <Specific>RuntimeException (This is rarer than you think)
  • Net effect is that when you come across a try-catch clause you better pay attention as interesting things are happening there.
