泛型方法+反射，解决静态可变类参数问题

问题描述：略

问题分析：略

具体代码如下：

Base是Lesson和Result的基类
public class Base {
public static Base parse(String str) {
return new Base();
}
}

Lesson
public class Lesson extends Base{

public static Lesson parse(String str){
return new Lesson();
}
}

Result
public class Result extends Base {

public static Result parse(String str) {
return new Result();
}
}

BaseList是LessonList和ResultList的基类
public class BaseList {

    public static <BaseListT, BaseT> BaseListT parse(String str,
            Class<BaseListT> listClass, Class<BaseT> itemClass)

    throws SecurityException, NoSuchMethodException, IllegalArgumentException,
            IllegalAccessException, InvocationTargetException,
            InstantiationException {
        
        BaseListT baseList = (BaseListT) listClass.newInstance();

        List<BaseT> list = new ArrayList<BaseT>();

        Method method = itemClass.getMethod("parse",
                new Class[] { String.class });

        for (int i = 0; i < 10; i++) {
            BaseT base = (BaseT) method.invoke(itemClass, str);

            System.out.println(base.getClass().getName());

            list.add(base);
        }
        System.out.println(baseList.getClass().getName());

        return baseList;

    }
}

LessonList
public class LessonList extends BaseList {

public static LessonList parse(String str) throws SecurityException,
IllegalArgumentException, NoSuchMethodException,
IllegalAccessException, InvocationTargetException, InstantiationException {

return (LessonList) BaseList.parse(str, LessonList.class,
Lesson.class);
}
}

ResultList
public class ResultList extends BaseList {

public static ResultList parse(String str) throws SecurityException,
IllegalArgumentException, NoSuchMethodException,
IllegalAccessException, InvocationTargetException, InstantiationException {

return (ResultList) BaseList.parse(str, ResultList.class,
Result.class);

}
}Test类测试类
public class Test {

public static void main(String args[]) throws SecurityException,
IllegalArgumentException, NoSuchMethodException,
IllegalAccessException, InvocationTargetException,
InstantiationException {

LessonList.parse("dfd");
ResultList.parse("dfd");

}
}
