declaring class inside a method using reflection in java

class test{
    public static void main(String[]args{
         new test();
    }
    void method(){
         class inside{
              int a;
              void methodinside(){}
         }
    }
}

I was declaring class using reflection like :

Class c=Class.forName("test");
Class[]cls=c.getDeclaredClasses();
for(Class cl : cls)
     System.out.println(cl.getName());

but, my program cannot finding class inside.
