java.lang.Object
- Contains methods all objects can access and make use of.
- toString() 
  * Often overridden, it allows a programmer-defined string to be output when an object of that type is an argument in a print(ln) statement.
  * If not overridden, placing the object var in a print(ln) outputs the class name followed by the object's address (prefaced with @. 

Collections Classes
- Starting in v 1.5, templated objects were introduced under the Collection s classes.
  * e.g. ArrayList can have a template argument; if used, no need to cast when using get().

Sessions
- Hold individualized information at the browser level, 
	i.e the session is held in a browser an is accessible to a server,
  * Data is stored as name-value pairs.

- Parameter of getSession() is whether to create.

Shopping Example
- Note the synchronized block
  * Only one thread may be active within that block at any time.
    > Threads access the protected block sequentially.

Cookies
- A cookie is an object in the session.
  * The servlet gets cookies from the request
  * Cookies are stored by the servlet in the browser session via the response.
- getCookies() returns all the cookies in Cookie[]. There isn't a search function. 
	You must manually search for the cookie you want.

Tomcat Issues:

	tail $CATALINA_HOME/logs/catalina.out -f
   If there is any issue that is affecting Tomcat, email me IMMEDIATELY so I can reboot Tomcat if necessary.
