例如，我有一个if子句，它始终为假（不是变量最终）。
public static final boolean FOO = false;
if (FOO) {
doSomething();
}
我希望它在Eclipse中以灰色的形式呈现，例如。 基本上，我希望它能像Visual C ++为不可达的宏一样完全工作。
Update: I want it to be shown real-time just like Eclipse compiles Java all the time when you make changes to code. This should be possible, shouldn t it? I know there are those dead code tools to do this afterwards but that s not what I like to do.
The next version of eclipse (3.5) will have this functionality.
It is currently available from 3.5 milestone 4 onwards as listed in the Eclipse 3.5 M4 - New and Noteworthy
You can get it now by using the latest milestone (3.5M5)

First, you should be aware this is something that is on the verge of being non-computable. Check out the halting problem, if you are unfamiliar with this subject.
Second, there are plug-ins which help in identifying dead code, up to a certain computable limit, such as PMD.
