How does javac -d work?

Answer 1

I've got it. So basically
javac -d "path" "file-name.java" is used to create the "file-name.class" file in the destination location as give in "path".

ex- if a file "A.java" is located in "C: " and you want to create the "A.class" in another location , say "D:/MyFolder" ,
you simply use this command inside "C:".
javac -d D:/MyFolder A.java , this will create the A.class file in D: MyFolder

Answer 2

According to Oracle documentation , javac -d sets the destination directory for class files.
does it have any other use?
