Quick Answer
Exceptions are runtime errors that disrupt normal program flow. Checked exceptions (IOException, SQLException) must be caught or declared with throws - checked at compile time. Unchecked exceptions (RuntimeException, NullPointerException, ArrayIndexOutOfBoundsException) don't need to be explicitly handled. Use try-catch-finally to handle exceptions. Create custom exceptions by extending Exception or RuntimeException.
Answer
Exceptions represent runtime errors. Checked exceptions must be handled. Unchecked exceptions don't require mandatory handling.
