Will it blend? +

Does the following code compile?
If not, which line causes the error?
If it compiles and runs without problem, what is the output?

public class $_$ {
    static public void main(String... _$_) {
        int _ = 3, __ = 5;
        for (int $ = 0; ++$ < _$_.length;)
            _ = ++__ + ((int)Integer.parseInt(_$_[$]));
            System.out.println(_);
    }
}

java $_$ 1 2 3

Don't expect to find such a code inside in our programs.
