修改结果
对我来说没有任何错误

edit
No errors for me

class Gene {
}
class MyGene extends Gene implements Comparable<MyGene> {
    public int compareTo(MyGene o) {
        throw new UnsupportedOperationException("Method is not implemented yet.");
    }
}

...

    List<MyGene> l = new ArrayList<MyGene>();
    Collections.sort(l);
