Question

I have an algorithm written in C and it has code which can be handled by C preprocessor but as there is no preprocessor in java i don’t know how to write java code to handle such thing.
The C code is

#ifdef Tile_size_utility
#define print_error 0
else
#define print_error 1
#endif

How can i implement this in Java?

Answer 1

 Class ErrorVerbose { 
          private static boolean enabled = False;

          public static setEnable(boolean enable) 
                enabled = enable;
          }

          public static perror(String msg) {

               if (enabled) {
               /* Print */ 
               }

          }
   }


 class YourClass {

           public YourClass(....,boolean status) {

                ErrorVerbose.SetEnable(status)
                    .
                    . 
           }

   }

Well, yes, either you can make is a non static class so that other classes can enable / disable verbose. Advantage of making a ErrorVerbose class is that you add more info like time, date, function name (which called), etc which makes it more informative I just gave a skeleton.
