Java / JDK, JRE, JVM, JIT

Difference between Java.exe and Javaw.exe.

Java is the plain old java interpreter, you have a console window open all the time. Javaw is a wrapper around java that doesn't open a console window.

java.exe pops up a console window. javaw.exe does not. If you expect text output, you'll need to use java.exe. If the application pops up its own window (For example, Eclipse), you can use javaw.exe.
