What is javaw.exe?

I know what is javac.exe?

But what is javaw.exe?

Java newbie here.

Like java.exe is to console programs, javaw.exe is for Swing/AWT programs.

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.

java.exe can also run Swing/Awt program.
