conditional compilation

[stmfc]

in C and C++ conditional compilation is very useful for debuging.
(using debugging MACROs)

java does not support conditional compilation. what can we use in java
to replace MACRO usage of C/C++ ?

There's no need for macros in Java.

Why would you like to have conditional compilation?

This comment is assuming you wish to use conditional compilation for environment changes such as simulation and non simulation runs. (I hope that make sense).

You can implement conditional compilations through interfaces, I'm guessing.
Use a text file to load different interfaces.

There's a small compiler facility: if the condition of an if statement is provably
false, the entire if statement doesn't generate any code at all:

public class Foo {
   private static final boolean DEBUG= false;
   ...
   public void bar() {
      if (DEBUG) {
         // no code will be generated here
      }
   }
}

kind regards,

Jos

Very Nice. Thank you.
