Throw vs throws - Java

  1. Throws clause in used to declare an exception and throw keyword is used to throw an exception explicitly.
  2. If we see syntax wise than throw is followed by an instance variable and throws is followed by exception class names.
  3. The keyword throw is used inside method body to invoke an exception and throws clause is used in method declaration (signature).
for Example
Throw
throw new Exception("You have some exception")
throw new IOException("Connection failed!!")
Throws
throws IOException, ArithmeticException, NullPointerException

EJB - Stateful vs Stateless

For  stateless session beans  the server can maintain a variable amount of instances in a pool. Each time a client requests such a stateless bean (e.g. through a method) a random instance is chosen to serve that request. That means if the client does two subsequent requests it is possible that two different instances of the stateless bean serve the requests. In fact there is no conversational state between the two requests. Also if the client disappears, the stateless bean does not get destroyed and can serve the next request from another client. On the other hand a  stateful session bean  is closely connected to the client. Each instance is created and bounded to a single client and serves only requests from that particular client. So happens that if you do two subsequent requests on a stateful bean, your request will be served always from the same instance of the bean. That means you can maintain a conversational state between the requests. At the end of the li...
