Question

java安装后bin目录下的javaw是用来做什么的？

如题。

Answer 1

javaw是不使用命令窗口的形式来运行java class文件。java是用命令行窗口的形式来运行java class文件。

Answer 2

网上截取的：
"javaw.exe" belongs to Java from Sun Microsystems, Inc..The javaw.exe command is identical to java.exe, except that with javaw.exe there is no associated console window. This implies you can't get it to display the version with -version, since there is no console to display it on. Use javaw.exe when you don't want a command prompt window to appear. The javaw.exe launcher will, however, display a dialog box with error information if a launch fails for some reason.

就是java.exe的一个无控制台窗口版本，功能和java.exe相同，不过用它运行java程序时没有console弹出，程序里的错误也是以对话框的方式弹出提醒的，比如抛出的异常。
