Why No #include statements?

Java maps fully qualified class names to a directory path, and therefore does not need an #include, #ifdef, etc. (and no preprocessor as well)

Thus:


java.awt.TextField

is mapped to:

java/awt/TextField

and dynamically loaded,

as needed.

David Dagon: This explains the mystery behind the error message reported when one attempts to run a file with the “.class” extension passed into the java VM:

java FooBar.class

Exception in thread "main" java.lang.NoClassDefFoundError: FooBar/class

Here, the VM looks for a file “FooBar in a folder called “class”

Also, some might argue that javadoc and doclets are types of preprocessors.
