S'mythology: Evolving Java - Increasing Demand To Remove Checked Exceptions
-
Naturally if you have existing code depending on a method signature (which includes exceptions) you have to catch any undeclared checked exceptions and (optionally) throw a declared exception or an unchecked exception.
The use of "throws Exception" in a method signature is a coding anti-pattern, used only if you want to give up all responsibility for handling errors. I certainly don't recommend it and similary I only recommend the "notry" keyword as a way to facilitate developers who want to opt out of dealing with errors. For simple non-critical programs this "philosophy" may be acceptable and I believe the Java language should support it.
Java theory and practice: The exceptions debate
-
Checked exceptions represent useful information about the operation of a legally specified request that the caller may have had no control over and that the caller needs to be informed about -- for example, the file system is now full, or the remote end has closed the connection, or the access privileges don't allow this action.
