It really isn't very easy to do this.  In general, you can do
something like

public class MyClass
{
   public static final boolean  HAS_CHEEZBURGER=true;

   public void someMethod()
   {
       if( MyClass.HAS_CHEEZBURGER)
       {
           doCheezburger();
       } else
       {
           noCheezBurger();
       }
   }
}

   The compiler I think will see that HAS_CHEEZBURGER is constant and
can never change, and may optimize away the branch not taken.  Perhaps
some more knowledgeable folk could comment on that.

  If on the otherhand, you really really think you need to do
preprocessing using eclipse and Java, you can.   See the following
link.
