Exceptions in Java

Found this nice article on exceptions in Java - from a historic overview of Oak, on checked and unchecked exceptions, and asynchronous exceptions it explains nicely (and with code examples) what the Java exception mechanism is about. What I like most are the best practices section, which applies not only to Java:

• Don't Write Own Exceptions
• Write Useful Exceptions
• Throw exceptions early
• Catch exceptions late
• Document exceptions
• Unit Test Exceptions
