How to set the output of a JAVAC compiled file [duplicate]

Answer 1

From man javac on my system:

-d directory
Sets the destination directory for class files. The destination directory must already exist; javac will not create the destination directory. If a class is part of a package, javac puts the class file in a subdirectory reflecting the package name, creating directories as needed. For example, if you specify -d /home/myclasses and the class is called com.mypackage.MyClass, then the class file is called /home/myclasses/com/mypackage/MyClass.class. If -d is not specified, javac puts the class file in the same directory as the source file. Note: The directory specified by -d is not automatically added to your user class path.

Hope that helps.

Answer 2

The output of javac is always classfiles, and the name of the file matches the name of the class contained within it. (A source file with multiple classes in will result in multiple output files.)

If you use the -d command line option, javac will also use the package of the class to generate a directory hierarchy, with the -d option specifying the root. Otherwise, each class file will be output in the same directory as the source file from which it was compiled.
