I suggest the author of this article stick to XML because he is the last person anybody looking for an intelligent, informed voice needs when it comes to enhancing Java. Anybody got any serious suggestions for enhancing Java? He sure doesn't.
The Complex Number class is tired and worn and he is coughing that up as his "personal" suggestion? The solution to that would be generics and operator overloading, not a naive suggestion to add one more class.
The suggestion that they eliminate the need for a semicolon at the end of a line suggests is simply stupid. Java does not require a semicolon ad the end of a line. If he doesn't GET the basic notion of a statement and the ability to terminate such a construct he should not be commenting on Java at all.
What you have here is some clown regurgitating a lot of old and misguided material based on pure ignorance. Do they have an "ignore" button for articles? Now there's a suggestion.
