Java not compiling .class files under $CLASSPATH
class, java, javac, package
Solution
You need to use the `-d` option to specify where you want the `.class` files to end up. Just specify the base directory; `javac` will create any directories necessary to correspond to the right package.
Example (based on your question):
javac -d ~/java/classes KeyEventDemo.java
Problem
I'm trying to figure out how organize source and class files working with packages. I found a very useful tutorial. But I still have some questions. As far as I understood it is a good practice to have an isomorphism between name of packages and name of the directories where elements of a package are stored. For example if I have a package named `aaa.bbb.ccc` which contains class `ddd` it is a good practice to have a class file called "ddd.class" and located in "$CLASSPATH/aaa/bbb/ccc/". Did I get it right? If it is the case, will Java compiler put *.class files into the correct directory automatically? I was not able to get this behavior. I set the `$CLASSPATH` variable to `"/home/myname/java/classes"`. I executed `javac KeyEventDemo.java` which contains `package events;`. I expected that javac will create a subdirectory `events` under `/home/myname/java/classes` and put the `KeyEventDemo.class` in this subdirectory. It did not happen. I tried to help to javac and created "events" subdirectory by myself. I used `javac` again but it does not want to put class files under "/home/myname/java/classes/events". What am I doing wrong?
