Java和Javaw的区别
both applications will run your program, and are very similar, but have one key difference - java runs it through a Java Console, while javaw does not.
The console is there mostly for text programs - for example, all your print statemements won't get printed if you run it using javaw. The same then goes for error messages, messages you print on the program's usage etc etc.
However a java console slows the program down some - since it's constantly listening to your program for things to output.
So, if you're choosing which to use:
If it's a text-based program, use java.
If it's graphical but prints text at any point, use java
If you're error checking, use java
If it's purely graphical, and you need to increase the speed, use javaw.
两个应用程序都能运行你的程序，并非常相似，但是有一个重要的区别，java通过控制台运行，javaw则不是。
控制台几乎是为纯文本编成的，例如如果你用javaw运行所有你打印的状态不会被打印出来。你打印在程序中的有用信息，错误信息也是一样。
所以，如果你在选择用哪个：
如果是基于纯文本的编成用java。
如果是图形化但随时打印成纯文本用java。
如果你在检查错误，用java。
如果程序是纯粹的图形化的，而且你需要提升速度，用javaw。
