One of Java's big draws is "platform independent" code. You can compile a Java file on Windows and run it on Mac OS, Linux, Solaris, or whatever other operating systems support Java.
Executable files must be made for each individual platform. An executable file made for Windows will not run on any other OS (and vice versa). Java producing executable files would just not make sense, since you would have to recompile your code for each platform.
