我正在尝试浏览所有使用自定义库反射实现接口的类。这是我的来源：

public static List<IModdable> getAllModClasses() {
    Reflections reflections = new Reflections("mod.api.core"); //getting error here
    Set<Class<? extends IModdable>> classes = reflections.getSubTypesOf(IModdable.class);
    List<IModdable> modList = new ArrayList<IModdable>();
    for (Class<? extends IModdable> c : classes)
        try {
            modList.add((IModdable) c.newInstance());
        } catch (Exception ex) {
            err(String.format("Could not load mod %s !", c.getName()));
        }


    return modList;
}

错误：

以下程序的输出是1,3,3可以有人解释一下吗？它会将10.25视为方法参数的对象吗？

public class Test {
  void methodOfTest(int i) {
    System.out.println(1);
  }

  void methodOfTest(Integer I) {
    System.out.println(2);
  }

  void methodOfTest(Object o) {
    System.out.println(3);
  }

  public static void main(String[] args) {
    Test t = new Test();

    t.methodOfTest(10);

    t.methodOfTest(10.25);

    t.methodOfTest(new Double("25.25"));
  }
}
