public class Something { public static void main（String[] args) { Other o = new Othe

public class Something {

public static void main(String[] args) {

Other o = new Other();

new Something().addOne(o);

}

public void addOne(final Other o) {

o.i++;

}

class Other {

public int i;

}

和上面的很相似，都是关于final 的问题，这有错吗？
