在运行时，找到扩展基类的Java应用程序中的所有类

我使用

org.reflections

Reflections reflections = new Reflections("com.mycompany");    Set<Class<? extends MyInterface>> classes = reflections.getSubTypesOf(MyInterface.class);

另一个例子：

public static void main(String[] args) throws IllegalAccessException, InstantiationException {    Reflections reflections = new Reflections("java.util");    Set<Class<? extends List>> classes = reflections.getSubTypesOf(java.util.List.class);    for (Class<? extends List> aClass : classes) {        System.out.println(aClass.getName());        if(aClass == ArrayList.class) { List list = aClass.newInstance(); list.add("test"); System.out.println(list.getClass().getName() + ": " + list.size());        }    }}
