Excluding parts of source code during compilation

Hi,
you could do something like:
static final boolean PRODUCT = false;
...
if (PRODUCT) {
//some code here
}
By doing so, the compiler will still compile the body of the if
statement, but it will generate no bytecode in the resulting classfile
(as the compiler can statically determine that the branch is never taken).
Note: if you change the value of the compile-time constant PRODUCT (i.e.
from false to true), it is recommended that you recompile the whole
project, as compile-time constants are inlined in client classes that
use them.
