eclipse 中其他包中的类如何调用默认包中的类（反射机制）

默认包中的类：

public class Hello {
public void print(){
System.out.println("hello");
}
}

其他包中的类：

      import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public class Hi  {
public static void main(String[] args) {

try {
Class c = Class.forName("Hello");
Method m = c.getDeclaredMethod("print",null);//得到Hello中声明为print的方法
m.invoke(c.newInstance());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}


}

结果为hello
