I had a similar situation in my own code earlier but it turned out IDEA was
doing the right thing. In your example you are assigning a value to count
but you are never using it. For it to be considered used you must, for
example, pass it as an arg to a method, or use it in a comparison or
calculation. Try the following:
public void test()
{
int count = 0; // count is unused
count = 7; // count is still unused
count = Integer.parseInt(System.getProperty("test")); // count is *still*
unused
int z = count; // count is now used, but z isn't!
}
It would be interesting if IDEA could figure out that since z is useless,
count is also useless! But I'm pretty happy with the way it is now; I would
probably start off by removing the line of code declaring z, then notice
that count turned a different color, and delete those as well (I'd then
delete the whole useless freakin method :)).
