Running a Java Swing Application by double click (w/o console)

Question

Suppose I have an executable JAR that launches a Swing GUI. If it is launched from the console (e.g. java -jar myapp) then the console is also used by the application (i.e. logs are being printed). This logging takes a bit time, it's quite verbose.

Note, that I only have a JAR, not the sources.

Question: what happens when you double-click run a JAR? Obviously no logs are visible, but are they simply invisible, or does this indeed boost the performance of the application (by skipping logging)?

Answer 1

If you don't want to see the console, use javaw to launch the program instead of java. So you would run: javaw -jar myapp.jar
