Hello Everyone, I am looking to ask some java related questions where I didn't get the exact answer till now. I have google it to find them and I have found some blogs like this. Can anyone explain to me about below questions query: 1. How does the throw keyword differ from the throws keyword? 2. Could you draw a comparison between Array and ArrayList? 3. Explain Interface in Java? 4. What is the join() method? 5. Understand by OutOfMemoryError in Java? 6. Could you demonstrate how to delete a cookie in JSP with a code example?
