Cannot find symbol :Class Dog

[geet kaur]

package com.example;


import javax.servlet.*;


public class MyServletContextListener implements ServletContextListener
{
		public void contextInitialized(ServletContextEvent event)
		{
			ServletContext sc=event.getServletContext();

			String dogBreed =sc.getInitParameter("breed");

			 Dog d=new Dog(dogBreed);
			
			sc.setAttribute("dog",d);
			
		}
		
                 public void contextDestroyed(ServletContextEvent event)
		 {

			
	
		 }  


}
								

package com.example;

public class Dog
{
		private String breed;
		
		public Dog(String breed)
		{
			this.breed=breed;
		}
		
		public String getBreed()
		{
			return breed;
		}
}

these are my two classes but when i try compiling the MyServletContextListener class it shows me the error, cannot find symbol:class Dog.However,both are in the com.example package

I ran this in NetBeans and it compiled for me without an exception.
