Question

I am told that javac is smart enough that it does not recompile the .java, in condition that this .java has a timestamp before that of .class. I just find it does not work like that in my machine, am I certainly wrong somewhere?

my P.java is located under .../eg/access, with P.java declared as a package of access

eg 
 |- access 
      |- P.class
      |- P.java

Then when I run javac P.java, each time it is recompiled, is that normal or am I wrong?

Answer 1

It’s normal that it is recompiled each time. javac doesn’t do incremental compilation.
