Java 与 Javaw 的区别

以下是官网的原话：
The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear. The javaw launcher will, however, display a dialog box with error information if a launch fails for some reason.

javaw其实就是java, 只是用javaw启动不会跟着一个控制台窗口。如果你要启动一个窗体， 并且不需要那个控制台， 用javaw, 如果程序运行出错了， 你要弹出错误对话框来代替System.out
