可变参数方法的反射和调用

可能编译不过去，改一改。手写的！

public class A{

          public static void main(String[] args){

                 Class c = Class.forName("B");

                 Object o = c.newInstance();

                 Method m = c.getMethod("add",new int[].class);

                 m.invoke(o,new int[]{1,2});

          }

}

class B{

      public void add(int... a){

          system.out.println("ddd");

      }

}
