Killer Game Programming in Java
By Andrew Davison
Here's the list of objections to Java:
Java is too slow for games programming.
Java has memory leaks.
Java is too high-level.
Java application installation is a nightmare.
Java isn't supported on games consoles.
No one uses Java to write real games.
Sun Microsystems isn't interested in supporting Java gaming.
It's worth saying that I think almost all of these objections are substantially wrong. Java is roughly the same speed as C++. Memory leaks can be avoided with good programming and techniques like profiling. Yes, Java is high-level, but it offers more direct access to graphics hardware and external devices. Installation isn't a nightmare if you use decent installation software. There's a growing number of excellent, fun Java games, and an enormous amount of support available from Sun and Sun-sponsored sites.
If you're keeping count, I haven't disagreed with the lack of a games consoles port, which is a tad embarrassing for a "write once, run anywhere" language. Things may be changing in this category, as I'll explain later.
A general point about these objections is that they had more validity in the late 1990s when the language and its libraries were less sophisticated and slower. Java's user and developer communities are burgeoning and have produced a plethora of useful tools, online help, and code examples. The games forums dedicated to Java barely existed 2 to 3 years ago. Java is a great language for games programming, as I hope this book demonstrates. Now, back to the criticisms.
上面是有名的JAVA工程师Andrew Davison写的一本书《Killer Game Programming in Java》
里面提到了JAVA的缺点 也提到了JAVA一直以来的发展 现在JDK6.0问世之后 (Java is roughly the same speed as C++)其速度和C++是几乎一样的
不要老是拿执行效率说事 难道大家都不看英文文档吗?现在的JAVA速度和C++没有太大差异
