4,254 PointsThere are tons of exceptions. You can even create your own. Probably the most common one you'll run into would be the NullPointerException.
NullPointerException: Thrown when an application attempts to use an object reference that has a null value. For example, if you were to run this code in an IDE, you would get a "NullPointerException.":
String helloWorld = null;
helloWorld.toUpperCase();
You're not going to use all the exceptions available to you. Probably less than 5% of them. I'll leave some helpful links that should help you understand them better.
